Meadow warblers

Posted on September 4, 2013 | 15 comments

Our migrant warblers were all back from Africa and nesting by the beginning of June. There are four species which normally frequent my local countryside, the blackcap (Sylvia atricapilla, Dansk: munk), chiffchaff (Phylloscopus collybita, Dansk: gransanger), willow warbler (Phylloscopus trochilus, Dansk: løvsanger) and the whitethroat (Sylvia communis, Dansk: tornsanger).

The blackcap have been conspicuous by their absence this summer. The central European winter population, of which a pair took up residence in the garden last winter, disappeared in the spring and that was the last time I saw one. Chiffchaff were, as always, the first winter visitor I noticed returning because of their characteristic song calling out from the trees. There are several other birds singing in the background here but the call of the chiffchaff is clear above the others, and it’s easy to see where it gets its name from.

It’s now at the start of September and I haven’t seen a chiffchaff for a while, but through the summer I regularly saw willow warblers which were nesting in a bramble thicket that I passed when I was out walking the dog. Willow warblers are very easy to mistake for chiffchaff by sight but willow warbler song is quite different.

The song isn’t the only diagnostic differentiator between these two species, there are a couple of others but they are more subtle. The most noticeable is the colour of the legs, chiffchaff have dark, almost black, legs and the willow warblers are red brown. Differences in plumage of the willow warbler are the brighter stripe over the eye (the ‘supercilium‘), a more promounced dark eyestripe and the patch under the eye (the ‘ear covert’) is olive grey with a pale patch immediately below the eye, compared to the more uniform dark grey colour of the chiffchaff. So if you get a good look through binoculars it’s not too difficult to tell them apart, but the song is the easiest way.

Another foray to collect flies for the chicks

Pausing to check up on me before heading into the nest

For a couple of weeks there was a spot in the field where I could stand close to the nest and watch the comings and goings of the adult willow warblers bringing food for the youngsters, and they seemed cautious but otherwise content for me to be there if I stood still.

Whitethroat male – my best ever bird portrait!

My favourite warbler is the whitethroat. They are easy to tell at a distance, even without optical assistance, and this is my favourite picture of one. The male whitethroat has a jingly jangly song and when he’s advertising for ladies he perches on top of a bush and flies repeatedly in a jerky motion straight up and then flutters back down to the same spot.

And while I was busy photographing the warblers I was being serenaded night after night by this chap:

A male songthrush (Turdus philomelos, Dansk: sangdrossel) filling the meadow with song

A tad incongruous in a post about warblers, I grant you, but he was there all the time and his songwas magnificent! As with the chiffchaff there are several other birds calling too, but the thrush is easily distinguishable from the noise. This is the first time I’ve posted a link to my own (amateurish!) sound recording, but I think it’s OK. Let me know what you think.

Insects and molluscs

Posted on June 4, 2012 | 28 comments

Over the last couple of weeks I’ve been out and about photographing wild flowers, and of course the raison d’etre of flowers is to produce the reproductive cells of the plant in order to ensure survival. And as plants are immobile they rely on other vectors to connect the male and female parts, that can be the wind and the rain but many flowers are exquisitely evolved to attract one or more species of insect to carry the pollen to the ovum and effect fertilisation.

So in the course of photographing the flowers some of them were hosting a pollinator or two:

Tree bumble bee – Bombus hypnorum

This tree bumle bee was sipping nectar from the flower of the white deadnettle. It’s one of the insects that is strong enough to get to the back of the flower and take the nectar. Flowers have evolved in this way such that the insects have to pass the stamen, which is where the pollen, or plant sperm, is produced. The stamen is made up of the filament and the anther, and foraging insects brush against the anther picking up pollen which they carry to the next flower where it is deposited on the female part of the plant – the ‘carpel’, and fertilisation ensues.

There are various species of bees in the UK but only around half a dozen common ones. Bees are in trouble in this country and no one seems to know why, both honey bees, which live in colonies, and solitary bumble bees are dying out at an alarming rate.

Buff tailed bumble bee – Bombus terrestris

The buff tail above was in a particularly poorly condition and had tiny mites crawling on it’s body so I imagine it didn’t do much more pollinating.

Soldier beetle – Cantharis rustica

The soldier beetles are related to the fireflies and they get their common generic name from one species which is bright red and is therefore named after the ‘redcoats‘ – English soldiers from days of yore. The larvae and the adults are carnivorous, the larvae feeding on insect eggs and caterpillars and the adults on aphids. They also feed on nectar and can therefore pollinate too.


Black slug – Arion ater

Alot of people have an aversion to slugs because of the damage they can do to fruit and vegetables, but this chap was out in the field making a meal out of a couple of dandelion seedheads. I don’t think they contribute much to pollination and they are predated by frogs and toads and also hedgehogs. Although I’ve heard that if too much of a hedgehog’s diet consists of slugs, parasitic worms living in the slugs can get into the lungs of the hedghog and kill it because its lungs fill up with fluid. Which sounds pretty unpleasant but I guess it’s not the fault of the poor old slug!


Brimstone moth – Opisthograptis luteolata

The brimstone moth is a splendid creature with a wingspan of 32-37 mm. It’s common and widespread across the UK. In the warmer climes of  the southern UK there can be three generations in a year but in the north there is only one brood per annum, and adults can be seen on the wing between April and October. The caterpillars feed on various trees and bushes including hawthorn and blackthorn.

A couple of weeks ago after days of rainfall which had moistened everything I found a 50m stretch of verge which was crawling, literally, with hundreds of yellow and brown snails.


Brown lipped snails – Ceppaea nemoralis. Just a few of the hundreds that were making the most of the damp conditions

The ‘lip‘ of the snails in their name is the front edge of the shell which can be seen in the next two pictures and is lighter brown on the yellow one and a much darker brown on the brown one:

Snails are predated by songthrushes. They pick up the snail by the fleshy part and crack the shell on a handy stone. Some years ago I was sitting at home on my own reading a book and everything was very quiet. I heard ‘tap tap tap’ on the front door, but when I went to answer it their was no one there. So I went back to my book. A few mintes later I heard the same tapping and again there was no one there, so I opened the door to have a look up the street and rather than a visitor there was a collection of broken snail shells on my front doorstep. It transpires the tapping I’d heard was a songthrush using my front doorstep as an anvil to swing the snails against and hammer open the shells!

Returning songbirds

Posted on May 10, 2012 | 22 comments

There’s a particular spot in my local meadow where there are some large clumps of brambles which are home to numerous species of bird including songthrush, blackbird, linnet and house sparrow. And in the summer chiffchaff, willow warbler, blackcap and common whitethroat are all there too. Chiffchaff have been here for a couple of months now, and willow warbler almost as long but I hadn’t yet seen a whitethroat, so I set off last Monday in the hope of seeing the first one of the year.

A cock robin singing to the ladies

There were many species of songbird in the meadow including the robin (Erithacus rubecula: Dansk: rødhals) and the house sparrow (Passer domesticus, Dansk: gråspurv) and the air was alive with the song of all these species.


House sparrow female

Robin and house sparrow are resident species in the meadow and I see them all year round there, but not the chiffchaff:

The chiffchaff (Phylloscopus collybita Dansk: gransanger), which is a warbler, and willow warbler (Phylloscopus trochilus, Dansk: løvsanger) can be very difficult to tell apart if only seen at a glance, but they can be distinguished by their song, of which more in the next post. This chiffchaff was one of a pair which were calling to each other and flitting around the bushes passing within a few feet of me on several occasions and seemingly unfazed by my presence.

Cock linnet

Resident in the UK is the linnet (Carduelis cannabina, Dansk: tornirisk), they disappear from the fields around Histon in the Autumn, presumably to congregate at a winter feeding ground, and they reappear in the Spring. And they have recently turned up in the meadow. Also resident, and present all year round, is the dunnock…


Dunnock, Prunella modularis, Dansk: jernspurv

… and the chaffinch:

Cock chaffinch, Fringilla coelebs, Dansk: bogfinke

There were no whitethroat back in the meadow last Monday but as you can see there were plenty of other birds. In the last week I’ve also seen kestrel, sparrowhawk and buzzard, blackcap, green woodpecker, jay and magpie.

I recce’d the meadow again this weekend and the whitethroat are now back from wintering in Africa. They are very distinctive and both sexes are easily identified by their strikingly white throat, and the males display by singing from the top of a bramble thicket or a sapling and flit 4-5m vertically into the air and then descend to land in the same spot. They’re lovely little birds, with a very distinctive song, and I’ll hopefully have some pictures to show you in the near future.

Birds and bee(flie)s

Posted on April 3, 2012 | 18 comments

The day after the cold weather put paid to my snake hunting exploits I decided to take the dog for a quick run in the afternoon. He had just had a small tumour removed from his back leg and so he had a lampshade on his head to stop him chewing his stitches and consequently this walk was only meant to be a short one, and I wasn’t even going to take my camera. But on the way out the door I decided because it was very sunny and very warm I would take my camera. And I’m glad I did because there was wildlife in abundance.

Peacock butterfly, Inachis io, sunning itself on the path

The air was abuzz with insects including butterflies. I really like photographing butterflies and peacocks are good because they present a medium sized challenge. If you approach with stealth and don’t cast a shadow on them they let you get to within a few feet. The peacock is a species that can be seen at any time through the winter as it can wake in response to warmer weather, but they emerge in spring around the end of March/beginning of April, so the timing for this one was spot on.  As I was photographing the peacock a sparrowhawk (Accipiter nisus, Dansk: spurvehøg) flew past at high speed, much too fast to enable a usable photograph, it’s always good to see a bird of prey because I think it suggests the prey species are in good order too.


Long tailed tit, Aegithalos caudatus, Dansk: halemejse

The field where I found the peacock butterfly has a corner which faces south west and it was sheltered from the wind and bathed in spring sunshine. It was really warm when I arrived there, so I stood still and watched and listened while the dog went off to explore, and the trees around were full of birds including the long tailed tit, above, and a song thrush, below.

Songthrush, Turdus philomelos, Dansk: sangdrossel

While the birds were capturing my attention in the trees, butterflies weren’t the only insects there. In my corner there were also beeflies buzzing around. I was keen to try to photograph them in flight which is a tad more challenging as they would hover for a few seconds before darting off at very high speed in zig zag lines. But they were making the most of the shelter from any breeze that prevailed in this sheltered spot and I spent a good hour trying to photograph them.


Beefly, Bombylius major

The beefly, as the name suggests is a bee mimic. It has a very prominent proboscis which is used to extract nectar, and the fur is part of the bee disguise. It is a very good pollinator but is detrimental to other pollinators.

It is detrimental because it parasitises other bees and beetles. And the way it achieves that is another of those bizarre evolutionary adaptations that even the most imaginative science fiction writer wouldn’t dream of. It mimics bees in order to get close to their burrows where using its legs the female will flick her eggs into the hole where it hatches and attaches itself to the host. Then the gruesome bit: it lies dormant until the host commences pupation and then becomes an ‘ectoparasite‘ which means it remains on the outside of its host but extracts the body fluids to fuel its own growth. After draining its host dry it reaches the pupal stage which can vary hugely in length and they have been known to overwinter before emerging as an adult the following year.

Beeflies have appeared in several blogs in the last week or so and there are some more very fine images here:

http://www.leavesnbloom.com/2012/04/bombylius-major-bee-fly-aerodynamics.html

Rosie from ‘leavesnbloom’ has a wonderful collection of images of Bombylius major and Harlan from ‘The Roused Bear’ has also captured one in Iowa in the U.S.:

http://therousedbear.wordpress.com/2012/04/07/a-fuzzy-bee-fly/

They can be found across the whole planet except Australasia.

More birds which appeared in the trees around while I was chasing beefly were the common or garden greenfinch and chaffinch:


Greenfinch male pecking at a twig
Chaffinch male just taking it easy

Both greenfinch (Carduelis chloris, Dansk: grønirisk) and chaffinch (Fringilla coelebs, Dansk: bogfinke) are common or garden, but are both beautiful birds, and they can be seen here in the U.K. all year round. But a species that isn’t here all year round and returns after its winter migration to north Africa is the chiffchaff (Phylloscopus collybita, Dansk: gransanger):

The chiffchaff, named after its characteristic song, is a warbler and despite being a small bird they are tough. Their migration takes them south across mainland Europe, across the Mediterranean Sea and into north Africa, to retrace their flight four or five months later in the spring. And despite the hardships associated with such a gruelling endeavour, according to the British Trust for Ornithology (BTO), there are around three quarters of a million territories in the UK. They are one of the first migrants to arrive back in the U.K. and can be heard singing as early as late February. But this my first one in Cambridge on the first weekend in April.

Springtime sojourn to the Suffolk coast

Posted on February 18, 2012 | 12 comments

Last week we headed off to to the seaside for a few days and our chosen detination was Dunwich, a tiny village on the Suffolk coast which in medieval times was the capital of the region and a thriving, wealthy port for moving cargo and people between East Anglia and the European mainland. It’s an amazing place with very interesting history which I wrote about in a post last year.

We stayed in my favourite inn called The Ship which has panoramic views over the Dingle Marshes which stretch several miles north to Walberswick, which is renowned for it’s annual crabbing champi0nship. It is also where the king of art nouveau, Charles Rennie Mackintosh moved to after he had abandoned architecture to become a watercolourist and where the series of flowers known as the ‘Walberswick collection’ was painted.

The marshes along this part of the coast are full of wildlife, including rare birds such as harriers and bittern, mammals such as otters as well as a host of marsh and heathland plants and the associated fauna. It’s a wonderful place. The view from our window at The Ship was generally dominated by low grey cloud which occasionally saw fit to rain on us, but even so the wildlife was much in evidence without even leaving the inn:


The tree opposite our window played host to numerous small birds including this house sparrow (Passer domesticus, Dansk: gråspurv) and blue tit (Cyanistes caerulius, Dansk: blåmejse)
And a couple of hundred metres beyond the tree were some pools of rainwater where lapwing and these teal were on parade each morningAnd beyond that was a ditch where a little egret (Egretta garzetta, Dansk: silkehejre) was hunting every day

So, as you can imagine, it wasn’t so easy to haul myself away from my nice centrally heated room and my cup of tea and go out into the wintry mornings, when I could sit by the window and see all this! But I eventually extricated myself and walked a circuit of the village taking in the local church and graveyard, the remains of the Franciscan Friary and the woods inbetween, and was very adequately rewarded. The local church has the remains of a medieval leper hospital in its grounds which is a fascinating place historically, but is now inhabited solely by sheep and snowdrops (Galanthus nivalis). There were no sheep while we were in there but the snowdrops were growing out between the melting snow.


Snowdrops infront of the be-lichened walls of the ancient leper hospital in the grounds of St James church


A lapwing pair pausing in the Friary between displays of breathtaking aerobatic excellence

The Friary is long deserted by the Franciscan brethren and is now a ruin, but it still plays host to the local wildlife. As well as the lapwing (Vanellus vanellus, Dansk: vibe) , there was a songthrush (Turdus philomelos, Dansk: sangdrossel) foraging amongst the  grassy tufts and robins (Erithacus rubecula, Dansk: rødhals) singing from the trees beyond.

A deciduous tree adjacent to the Friary was completely covered in lichen

I don’t know which species the lichens are on the tree trunk but I think there are at least four. The flat resupinates can be seen on old wood and even brick walls in towns and villages, but the feathery species are much more susceptible to atmospheric pollution and therefore only exist where the air is clean.

Beyond Dunwich to the south is the gorse covered heathland of Dunwich Heath which is owned and managed by the National Trust, and beyond that is the RSPB reserve at Minsmere where I watched a marsh harrier quartering the reedbeds and where another walker told me he had seen smew and a bittern in one of the lakes on the reserve. I went to look there but I didn’t see either, but I did see other birds, and some splendid lichens. Of which more in a later post.

Robins and rails

Posted on November 6, 2011 | 6 comments

I headed down to the RSPB reserve at Fowlmere south west of Cambridge early yesterday morning (Saturday 5th November, 2011) with my friend and fellow wildlife enthusiast, David, where I was hoping to catch sight of a merlin or a kingfisher or another water bird which I don’t see in my regular haunts. It was a murky, grey morning and the air was holding so much moisture it felt damp. Consequently, conditions for photography were challenging,

Looking across the reedbeds at Fowlmere, distant trees looming out of the mist

Probably due to the weather it wasn’t easy to see the resident birdlife. We heard a great spotted woodpecker (Dendrocopos major, Dansk: stor flagspætte) from the car park but once we entered the reserve it was really quiet, apart from the faint roar of the traffic on the A10 and the occasional jet heading into Stansted airport. But of birds, there was not too much evidence. We heard some redwing (Turdus iliacus, Dansk: vindrossel) and fieldfare (Turdus pilarus, Dansk: sjagger) as they passed overhead unseen, and as we got close to the Reedbed hide a robin (Dansk: rødhals) and a songthrush (Turdus philomelos, Dansk: sangdrossel) were lurking in the bushes near the entrance and a stoat scampered across the bottom of the steps into the hide. From inside the hide we could see 15-20 mallard (Anas platyrhynchos, Dansk: gråand) on the water, and perched on a fencepost on the opposite side of the water was a kingfisher (Alcedo atthis, Dansk: isfugl).

I like the segmentation in this picture and the physical delineation by the fence of the cut and uncut reedbeds. And of course, the tiny spark of blue and orange of the kingfisher sitting in the middle.

Also on the lake was a heron (Ardea cinerea, Dansk: fiskehejre) fishing in the shallows and half a dozen teal (Anas crecca, Dansk: krikand), and a muntjac deer wandered by. The kingfisher subsequently vacated and no further avian visitors appeared so we vacated too and made our way to the Drewer hide where we’d been told a water rail (Rallus aquaticus, Dansk: vandrikse) was busy feeding. And it didn’t let us down.

The water rail is from the same family as coots, gallinules (moorhens) and crakes and lives and feeds in and around shallow water predominantly on animals but also some plant material.

…looking for invertebrates in the mud


And whilst this charming waterbird was busy captivating my attention a robin was flitting between a nearby hawthorn bush and the reeds:

The robin seemed a tad out of place in the reeds, but a lovely dash of colour on a grey morning with its reflection in the pond


From the front it’s apparent that the water rail is a very slim bird facilitating easy movement between the stems in the reedbeds. I can’t remember the last time I saw one so it was a treat to see this one so close and it loitered for getting on for an hour, until after we left.

The birds and the bees (and the flowers)

Posted on May 23, 2011 | Leave a comment

As our warmest and driest Spring on record turns into what is shaping up to be a warm and dry Summer, nature’s great events are occurring apace to exploit the prevailing climatic conditions.

The first swifts were seen over Histon 3 weeks ago (by me at least) after their heroic journey back to their breeding sites from overwintering in Africa. To celebrate this event I’ve spent several hours sitting in the garden of the Castle pub on Castle Hill in Cambridge enjoying a few convivial sharpeners and watching the swifts shrieking through the sky like an avian aerobatic team. I can heartily recommend both activities!

Wild flowers, including one of my favourites, white campion, are now in bloom:

White campion, Silene latifolia, decorating ditches and hedgerows

White campion is a dioecious plant which means the male and female reproductive machinery are on separate flowers. It grows in well drained earth and flowers from Spring to Autumn and is now delineating my walks across the open countryside. Another one of my favourite wild flowers is red clover (Trifolium pratense) which is a gorgeous colour and provides nourishment for bumble bees:


Red clover flower being harvested for pollen and nectar by a common carder bee (Bombus pascuorum). This is the national flower of Denmark.

And of course the local birdlife has been very busy breeding and raising chicks. Alot of species started this process earlier this year due to the unusually warm weather in Spring. I have a pair of blue tits raising a brood in the nestbox in my crab apple tree and my friend told me of a family of song thrushes which fledged from his garden a month ago. Which is very early.

A pair of great tit have been feeding their chicks on crushed peanuts which I put out on my bird feeder over the last month and last week they fledged and the whole family were feeding in my garden for just a day or two before they ventured further afield. (If you put nuts out for the birds during the breeding season please make sure you use crushed nuts as inexperienced parents can try to feed whole nuts to chicks and this can have fatal consequences). Great tits have over 70 different vocalisations which I think is remarkable, almost simple language! And on my explorations along the fields and hedgerows around Histon last weekend (21st May, 2011) I saw more great tit, blackcap and whitethroat all feeding gangs of fledglings:


Common whitethroat male, Sylvia communis

There are two species of whitethroat to be found locally, the common and the lesser (Sylvia curruca). They are distinguished by their song, which I won’t try to describe because I’ve never yet read a book which gives the remotest idea of what birdsong actually sounds like by a written description! But if you want to compare them try here for the common whitethroat, and here for the lesser whitethroat.


And another male whitethroat, this chap was singing long and loud, punctuated with characteristic jerky flights straight up in the air and back to the same spot

There are a good number of common whitethroat in the hedgerows north of Cambridge, lesser whitethroat are also here but are not so numerous. There are other distinguishing features between the two species, the lesser, as the name suggests is smaller (~11cm long compared to ~13 for the common), and is generally more grey with a pale grey head and noticeably darker grey ‘ear’ patches. It also has dark grey legs. Both species overwinter in sub-Saharan Africa, the common in central Africa and the lesser in eastern Africa.

Linnet can be regularly seen flying around the bramble thickets on the edges of the village and perching and singing on top of them. On Saturday early in the morning a fracas was going on in an elderbery tree in Rowleys Meadow in Histon which ended when a jay was chased out of the tree by a family of linnet and a family of whitethroat. The jay alighted on an adjacent shed to suss out the lie of the land and contemplate another raid whilst the indignant songbirds dispersed into some scrub to hide. Eventually the jay decided to keep his powder dry and disappeared into a nearby wood. Jays, like other members of the crow family, will raid nests of smaller birds for eggs and chicks, so it’s a perilous business being a small bird with a family to rear.


A linnet male perching on a bramble. When they’re not protecting a nest I’ve managed to sneak within 15 feet of linnet perched like this.

Linnet, Carduelis cannabina, are abundant resident and migrant breeders, although their numbers, as with many of our songbirds, are declining, and they are also passage and winter visitors. Due to their declining numbers over the past 40 years or so their conservation status is red, indicating they are globally threatened. They are finches which live in open country and farmland and feed on seeds.

Many species of moths, butterflies, bees, flowers and a plethora of other creatures are all appearing as trhe seasons are progressing and there’s something new to see every week!

April birdwatch

Posted on April 26, 2011 | Leave a comment

The activities of the birds in my garden have changed significantly in the last 2-3 weeks. Until then I was seeing multiple blackbird, robin, starling, goldfinch, chaffinch, dunnock, blue tit, great tit, collared dove and house sparrow with less frequent visits by long tailed tit. Since then a pair of wood pigeon have virtually taken up residence in my back garden and hoover up all the bird food before the smaller species get a look in. There is still the occasional dunnock and blackbird on the ground and much less frequent visits by blue tit, robin, starling and chaffinch but the goldfinch have all but vacated. This is interesting because when I’m outside I regularly see and hear groups of goldfinch in the trees around the garden but something seems to be keeping them away from my feeder.

My friend Chris told me he had a songthrush rearing chicks in a nest in a tree in his garden and she fledged four youngsters last week, which is very early in the year, so hopefully she’ll fit in another brood this year. But his garden has been subject to the attentions of a sparrowhawk in recent months so he was worried it would catch the fledglings, but clever use of carefully placed hanging bamboo canes has successfully deterred the hawk and all four fledglings seem to have successfully flown the coop. Songthrush 4, sparrowhawk nil.

Continuing with garden birds, last week it occurred to me that the fat balls hanging in my front garden were requiring replenishment rather more frequently than usual so I guessed the nesting birds were feeding more often. The reason turned out to be rather more amusing:


One of the local rooks has worked out that these are edible…

…and that it can reach them. And it takes alot of fat ball to fill a hungry rook!

Slightly further afield in the hedgrows and scrub bordering the farmland around Histon it’s a very good time to survey the local wildlife. As I mentioned in a previous post many species of wild flower now including forget-me-not, yellow archangel…


Forget-me-not

Yellow archangel – Lamiastrum galeobdolon, this variegated version is an invading subspecies ‘argentatum’

…herb robert, cow parsley and periwinkle are all in bloom and lining the paths through the countryside filling them with a palette of colour.

And in the fields, trees and bushes there is an abundance of birdlife:


Corn bunting perched in the midst of a field of oil seed rape

The countryside is ablaze with the yellow of rape flowers right now and just occasionally a photographic opportunity such as this one arises. I’m not particularly keen on the vast swathes of rape but it created a lovely backdrop for this corn bunting which are becoming increasingly uncommon.

It’s not unusual to see and hear bullfinch in one patch of scrub near the church in Histon, which is a regular destination for my birdwatching outings. That makes me very happy because I used to see them all the time when I was a kid in the 1970’s but since the 80’s they seem to have been persecuted to near extinction in alot of the UK because of their fondness for the green shoots of commercial fruit trees. They are still fairly elusive but I managed to get this photograph of a male (just!):


Male bullfinch – the female has similar markings but they are not pink she is more pale grey/brown

And in the same field as the bullfinch linnet are in residence, as are willow warbler, chiffchaff and blackcap which have now returned from over wintering in Africa:


Blackcap male

Chiffchaff

…as are whitethroat:


A female whitehroat, one of a pair patrolling a patch of brambles in the middle of the field

This field is an amazing place, I reckon it’s approximately 10-12 acres and it comprises several habitats including open-ish grass, it’s sorrounded by some old established trees: oak, ash and horse chestnut with hedgerow joining up the old trees consisting mainly of hawthorn and in the field itself there are alot of ash and other saplings and some large patches of bramble. Consequently it provides good supplies of food and cover for nesting for a number of different species. Green woodpeckers can be constantly heard yaffling to each other:

…and birds of prey including kestrel, sparrowhawk and buzzard are regularly in the skies above. The green woodpecker are there all year round and are usually hidden in the grass so I’ll flush one off the ground only for it to disappear into a tree too distant to allow a photograph. So this is about the best image I have of one. Most of the common or garden birds are regulars here too, house sparrow, dunnock, blue tit, great tit, long tailed tit:

…and chaffinch

…blackbird, songthrush, rook, crow and magpie are all present every day. So a small area of mixed scrub an the edge of the village supports a wonderful number of our birds.

There’s lots to see by simply look up in the village too. On the way back from the playground in Impington with my kids today we cycled along a road under a tree as a jay emerged from a silver birch on the other side of the road and landed in the tree a few metres over our heads. We all stopped to look at it and marvel at it’s amazing colours, and it looked at us for a minute or two before flapping off higher up the tree.

Guns Lane bird walk 2nd April 2011

Posted on April 2, 2011 | 1 comment

I acquired a voice recorder last week. It’s tiny – not much bigger than a  cigarette lighter – and it means I can record what I see alot more accurately as I don’t need to rely on memory. Which is a good thing as my memory is not brilliant. The weather was glorious on Saturday and Sunday morning so the timing of my acquisition was pretty good because there was an awful lot to record when I was out and about.  The birds are very busy right now building nests and in the last couple of weeks blackbirds have been collecting strands of hay ejected from the rabbit hutch in my garden and I’ve seen various other species with beaks full of grass, twigs and moss.

Apart from enjoying the sunshine I saw two species of bird for the first time this year – blackcap and linnet. A pair of linnet appeared to be in residence in a bramble at the southeastern end of Rowleys Meadow, Histon. (On the map, Rowleys Meadow is the area of green scrub in the middle.)

The blackcap were in the northwestern hedge row at the opposite end of the field to the linnet and perched, tantalisingly, directly over my head, so my photographs are all of the underside. I saw one pair together and two individuals on this walk which is almost as many as I’ve seen in Histon in total in the last three years.

Also in the same hedge along the northwest periphery were several yellowhammer and in the bright sunshine the colours were amazing:

Yellowhammer are a species of bunting that are resident in the UK so can be seen all year round and breed here. They feed predominantly on seeds but also on insects which they harvest from the ground. I often see them perched on top of hedgerows and they fly to the ground when flushed where, despite their colour, are often next to impossible to see. The female has similar markings to the male but  is much less yellow.

Yellowhammer are currently on the red list due to the decline in numbers over recent years, although there seem to be good numbers in my locality and I’ve even had one feeding in my garden!

Many species of birds were busy this weekend, including a buzzard, a pair of sparrowhawk wheeling around way up high, and a pair of kestrel. Closer to the ground, blacdbird, chaffinch, greenfinch, long tailed tit and songthrush were all very much in evidence.

Butterflies are also starting to emerge in the warm weather and a couple of red admirals and two others which I couldn’t see close enough to identify were floating along the brambles.

A good photograaph of a blackcap eluded me this weekend as I only managed to shoot it from directly underneath so the cap wasn’t visible, but I shall have another look this weekend and hopefully post a ;picture next time.

Histon forays, weekend 5th – 6th March 2011

Posted on March 6, 2011 | Leave a comment

This weekend I’ve been out and about on my regular walks north of Histon. (Click here for a sketch map of the locality). Yesterday I was out around the fields to the north between Histon and Cottenham. It was a cold grey morning and it was noteworthy for several reasons.

The birdlife was plentiful. (Click here for my wildlife diary where I’ve listed all sightings). Just a few minutes after telling my friend, David, that I hadn’t seen a corn bunting for around 6 months but that they frequent that area in numbers during the summer and disappear very quickly after the harvest, we saw one sitting in a bramble:

It was the first one this year and the first of several we spotted yesterday. It was a good morning for buntings in general. Last time I was here, around three weeks ago a mixed flock of reed bunting and yellowhammer were  in the east end of the Owl Shed Hedge (see post from 29th Jan entitled “Buntings abound: 29th and 30th January 2011“). They were there again on Saturday and reed bunting were present in most of the hedges and ditches we peered into. Skylark were present in large numbers too, singing up high and darting around low. A look  on the floor of the Old Water Pump, which has a platform for barn owls to roost and breed, revealed numerous owl pellets most of which were very old, but some of them looked fresher, possibly from within the last 6 months.

This is a very good thing as barn owls haven’t bred there since 2008 and I haven’t seen one in the vicinity since last year, and then only a couple of sightings all year.

Other appearances which livened up the walk were a muntjac deer, Muntiacus reevesi, introduced from China to the UK in the first half of the 20th century, which was rooting around at the back of the gardens of the houses on Cottenham Road, and a stock dove was sitting in the trees in the same area. I may have seen these before and mistaken them for wood pigeon, but David’s expert knowledge put me straight on the differences. They don’t have the white neck and wing bands of the wood pigeon and they have a dark eye which is diagnostic – that of the wood pigeon is lighter.

I set off in the other direction this morning to head out of Histon north west towards Oakington along Guns Lane and into Rowleys Meadow. I took a slow walk and was very adequately rewarded. Right at the start of the Lane where it joins Cottenham Road blue tit, great tit, greenfinch, chaffinch, starling and song thrush were present and finches were singing constantly,

…and a chaffinch male displaying his gorgeous black and white tail in a fan. I’ve posted a few photographs of chaffinch lately, even though they’re common I think they’re spectacular!

A couple of surprises today, firstly the number of bullfinch; I saw a single male in Rowleys Meadow which may have had a female with it but I couldn’t see it well enough to confirm, and another pair of males flew along Guns Lane hopping from hedge to hedge infront of me for 50-100m. And secondly, the number of dunnock. They were present in every bush and bramble in the Meadow and on the Lane singing constantly – if you haven’t heard dunnock song, have a listen here, it’s lovely.

Dunnock have a rather interesting approach to breeding. They don’t pair off as most birds do, a female will be mated by at least two males who will stimulate the females to eject a rivals sperm from the cloaca with their beak. DNA analysis has shown young in the same clutch can have more than one father. I like dunnock, they look boringly grey/brown when seen flitting around the undergrowth, but when they catch the light they are certainly not drab. And their song and their antics at breeding time are anything but boring!

Just as I was about to leave the countryside and head home I noticed a pair of starling sitting on top of a hedge checking out me and the dog. As I turned to point my camera at them they didn’t fly away but simply kept an eye on me so I could get this picture:

The glorious plumage of the starling!

Spring is well underway now and the activities of the wildlife are reflecting that. It’s a great time to be poking around in the woods and hedgerows.
