Serendipity II – The charismatic cuckoo

Posted on May 30, 2012 | 24 comments

I don’t recall having seen a cuckoo before, even though I’ve heard their unique call many times. But on my sojourn over to Wicken Fen a couple of weeks ago there were lots of them. ‘Lots‘ is a relative term because cuckoos are becoming increasingly scarce, their conservation status is red due to recent declines in the breeding population and in 2000 there were 9.6-19000 breeding pairs in the UK. But on this trip we heard and saw at least 5 and possibly several more.

Just before I spotted the first cuckoo I glanced across the lake and this was the view:

A pair of shoveler in the foreground, a little egret behind and a roe deer just beyond the reeds

I really like this picture because of the colours of the reeds and the water in the evening sunshine, but also because it contains three interesting species. Apart from rabbits, any wild mammal is exciting to see in this country, so the roe deer was a pleasing encounter. The little egret (Egretta garzetta, Dansk: silkehejre) is a member of the heron family which is now resident in the UK, presumably as a result of climate change. I associate them with warmer places because that’s where I saw them before 2000, but nowadays they’re not particularly uncommon here. And in the forefround are two shoveler (Anas clypeata, Dansk: skeand) which are migrant visitors to the UK, but this pair obviously liked it enough to linger and are still here in the middle of May, long after they would normally have left.

And then there were the cuckoos:

A pair of cuckoo, Cuculus canorus, Dansk: gøg

The cuckoo is an incredible bird and until very recently it was poorly understood. Last year the British Trust for Ornithology (BTO) managed to tag five male cuckoos with tiny satellite tracking devices and found out that they headed to the tropical sub-Saharan rainforests of Cameroon and the Democratic Republic of Congo. The cuckoo arrives back in England from Africa in late March or April and departs in July or August. It leaves earlier than other species because its parasitic breeding strategy removes the need for chick rearing. That means the cuckoo spends a minimum of 8 months a year in Africa so to call it a British bird is, I suppose, less than accurate, even though it breeds here.

The classic hanging wings pose which I always associate with the cuckoo

The tagged birds were all fitted with solar powered devices which transmit location data once every 48hr. The tracking data revealed that all five birds headed south over France and across the Mediterranean before heading down across Africa to Cameroon and DRC. All five made it. One of the birds died in Cameroon and two more died on the way back, but two of the five made it back to East Anglia this year. I believe the BTO plan to tag more birds including females and I’m very keen to see the results of that experiment.

The cuckoo is an iconic bird in the UK and it’s call is very distinctive. The call is generally recognised as a signal that Spring has arrived and there are local traditions around the UK based on the cuckoo. It is said in Worcestershire that the cuckoo is never heard before Tenbury Fair on April 21st or after Pershore Fair on June 26th. The song actually changes in June from the characteristic ‘cuck-coo‘ song to a shortened ‘cuck‘, and there is a rhyme about this:

In April I open my bill
In May I sing night and day
In June I change my tune
In July far far I fly
In August away I must

My Dad remembers a similar rhyme he used to sing when he was a kid in the 1940’s which was essentially the same but with some local Northamptonshire words substituted in.

I’m not quite sure what these two were doing but they were acting as a pair, and every minute or two one of them would dive off into the adjacent reedbeds to return a minute or so later. As I mentioned above, cuckoos are parasites and they could have been looking for nests to parasitise. There breeding strategy is unique, at least as far as I know. They lay their eggs in the nests of one of three other small songbird species: the reed warbler, the meadow pippit and the dunnock. All of these are the size of a sparrow (ish) so are much smaller than the cuckoo which is dove-sized, which I guess guarantees that the cuckoo chick will be much bigger than its ‘siblings’ and it won’t be threatened. The cuckoo chick then ejects the other chicks from the nest to die and the parents assume it is one of their own and feed it until it fledges. I’ve seen film of a cuckoo chick turfing out the other chicks and it’s a remarkable process, and not particularly pleasant to watch!

Despite their unsavoury procreation habits they are spectacular and charismatic birds and I hope the BTO research can find ways to guarantee their continued return here to brighten up the Spring and Summer.

The wild flowers are blooming

Posted on May 20, 2012 | 16 comments

A combination of the recent rains and the rising temperatures we’re getting now is creating ideal conditions for wild flowers. Any piece of uncultivated land is starting to bursting forth with flora which in turn is providing food and cover for flies, bees, beetles, butteflies and a plethora of other insect life. Which is also good for the birds, small mammals and other predators, and so on up the food chain. And on top of that it’s lovely to look at. So here’s a selection of flora currently blossoming in my patch of East Anglia:

Ground ivy – Glechoma hederacea

I like ground ivy because it occurs early in the year, first appearing in March, but like many other phenological phenomena it may now be happening earlier. It creeps across the ground, like ivy, forming carpets of blue flowers and with the green and red leaves it adds lots of colour to the undergrowth. It has numerous names and here are a few from the Royal Horticultural Society website: Devils candlestick, creeping charlie, crows guts, wild snakeroot, hens and chickens, gill-go-by-the- street, and my favourite: ale gill.

Another creeper which grows across the ground and in hedgerows and which has lovely blue flowers is the periwinkle. There are two types of periwinkle, the lesser (Vinca minor) which may have been introduced to the UK and the greater (Vinca major), which was introduced (both according to my wild flower guide).

The greater periwinkle

I’m a tad confused by this flower because they are meant to have 5 petals but this one only has 4. It is also known as creeping myrtle, cut-finger, flower of death (!), grave myrtle, and sorcerer’s violet, among others.

Sprouting next to this periwinkle flower was a nascent white deadnettle, Lamium album. It normally has white flowers which haven’t yet arrived, but the closed buds are visible below the crown. Everything is very green at the moment because of all the rain and looks beautiful against the red wing cases of the ladybird .

White deadnettle about to burst into bloom

Greater celandine, Chelidonium majus

It is thought the greater celandine is named after the swallow (‘khelidon’ is Greek for swallow) and it’s a member of the poppy family. When the stems are broken they ooze a latex sap which is as yellow as the flowers, and the colour can be as deep as orange. It contains a host of alkaloids which confer therapeutic properties but it can also be toxic. It is also known as cocks foot, sight wort and wart wort as the sap has been applied as a treatment for warts. I’m not sure where ‘sight wort‘ comes from, but if it burns off warts I wouldn’t want it anywhere near my eyes!

Cow parsley – Anthriscus sylvestris

As far as I know cow parsley doesn’t have medicinal properties and according to Wiki it’s not pleasant to eat. But I think the flowers are lovely and they bring back childhood memories of running through the woods in springtime when the cow parsley or ‘keck‘, as it was referred to by my Dad, was as tall as me. There’s nothing quite like a forest floor which is full of cow parsley, in it’s own way it’s as iconic as blue bells. It’s also known as wild chervil and Queen Anne’s Lace.

Beefly – Bombylius major

At the end of my flower finding mission I was looking for a ground ivy flower head and I found this little beauty, and just as I was just about to open the shutter a beefly zoomed in to sip the nectar. Flower pictures can benefit from some insect action and I like beeflies, so this was a highly serendipitous encounter!

Erratum: Maggie from ‘http://www.intouchwithnature.co.uk‘ has pointed out that the last flower with the beefly on is in fact red deadnettle – not ground ivy. So a big thankyou to Maggie for keeping me honest with my plant identification 🙂

Wild Geese

Posted on May 5, 2012 | 15 comments

At the same time I was experimenting with ISO and coots at Milton Country Park there were geese in the vicinity too. A small flock of greylag geese (Anser anser, Dansk: grågås) were grazing in a field immediately adjacent to the park.

There is another flock of greylags I encounter every day on my way to and from work. There are around 20-30 that have taken up residence in a field that is on my cycle route. The field is adjacent to a lake and the cycle path passes between them and every morning I pass by there are numerous heads poking up above the crop. I’m surprised the farmer puts up with this because the field now has a number of large threadbare patches as a result of the goose activity. But the geese have been there for a couple of months now and so far he hasn’t shot them so I imagine he probably doesn’t plan to. Which I’m rather pleased about.

Five of a small group of greylags ensconced in a field immediately adjacent to Milton Country Park

The RSPB website tells us that the greylag is the ancestor of domestic geese and is one of the largest and bulkiest geese native to the UK. It also describes it as ‘uninspiring‘. However, a few weeks ago on my way to work the flock of greylags were spooked and flushed up into the air. They headed for the safety of the lake which was only around 75m away so they didn’t need to gain height and one of them veered around and was heading straight for me at headheight. We simultaneously computed that if we continued on our current trajectories the end result would be an ugly collision twixt self and goose! So I braked and the goose wheeled, and it duly arrived at the lake unscathed, passing a few metres in front of me. My adrenaline levels were significantly elevated for the remainder of my journey to work and I can attest to the fact that this particular greylag was indeed very large and very bulky. And anything but uninspiring.

A lone canada goose – I like the symmetry of the reflection

The canada goose (Branta canadensis, Dansk: canadagås) was introduced to the UK and is now a resident breeder here and can be seen all over the UK apart from northern Scotland, and like the greylag it feeds on vegetation. I think it’s a handsome bird.

The indomitable coot

Posted on May 2, 2012 | 10 comments

The coot (Fulica atra, Dansk: blishøne) is a common water bird found on lakes and rivers in all of the UK apart from north west Scotland. They are related to the rails and crakes, they are extremely aggressive and will see off bigger birds who are sufficiently unwise to encroach on their territory.

Whilst wandering around the lakes at Milton Country Park on Saturday it was early in the morning and the light was really murky, so I experimented with the ISO settings to try and extract some half decent images from the gloom, and in these two images the ISO was 1600 or higher. The high ISO has given the pictures a slightly grainy feel, but that’s to be expected, and I like the colours:

The coot was diving repeatedly and resurfacing with beaks full of weed

I like the colours and the reflection of the beak

Apparently the baldness as in ‘bald as a coot’ comes from the white saddle above the beak, which I think is a tad strange because the chicks really are bald.

Coots are omnivores and their innate aggression extends to their chicks which when food is short they discourage from begging by biting them, sometimes so hard it kills them. It’s a tough existence being a coot chick, they are also regular prey items for other creatures such as herons. On a busy lake with other species of birds the coots are good fun to watch as they chase off allcomers.

Carduelis (or Chloris) chloris

Posted on April 24, 2012 | 23 comments

A sound I hear frequently at the moment when I open a door or a window which stands out from all other birdcalls is the call of the male greenfinch. It’s quite variable in tone from fairly high pitched, as in the recording here, to lower pitched where it almost sounds like a whirring mechanical toy.

The bird in these pictures has a reddish hue to it because it was being lit by the evening sun as it was getting lower in the sky, and also from the reflected light of the rusty ironwork and insulators of the electricity supply cables:

Greenfinch male calling from the top of a telegraph pole

The female greenfinch is similar to the male but her colours are much more drab, she is darker grey/brown without the vibrant green of the male.

The greenfinch is a resident breeder in the UK and can be found in gardens and parks at all times of the year feeding on bigger seeds and sometimes insects when rearing youngsters. It has a chunky beak which is typical of finches and is custom built for cracking open seeds.

The taxonomic name for the greenfinch is listed in some references as ‘Carduelis chloris‘, as in my RSPB ‘Complete Birds of Britain and Europe’ by Rob Hume published in 2002, (RSPB – Royal Society for the protection of Birds) ISBN 0751373540, and also in the RSPB Bird Identifier website. But in the BTO BirdFacts website (BTO – British Trust for Ornithology) and in my Collins Bird Guide 2nd edition from 2010, ISBN 978 0 00 726726 2, it is listed as ‘Chloris chloris‘ (Dansk: grønirisk). Somewhat confusingly the BTO entry goes on to explain that the name derives from ‘carduelis‘ meaning ‘goldfinch’ and the Greek ‘khloros‘ meaning ‘green’. So it appears that the two names may be interchangeable. Incidentally, the chemical element chlorine also derives its name from khloros as it exists as a green gas.

He’s turned round to keep on eye on me – his seed-cracking beak clearly visible

The poor old greenfinch has taken a bit of a battering in the last few years since 2005 from the trichomonad parasite which causes a disease called trichomonosis. This microscopic parasite lives in the upper digestive tracts of several birds species including other finches, house sparrows (Passer domesticus, Dansk: gråspurv) and pigeons and doves. I’ve heard that feeders may become contaminated by pigeons from where it infects the smaller birds. It’s particularly unpleasant (as are most parasitic infestations!) because it causes the throat to swell to the point where the birds can’t swallow so they eventually die of starvation.

Fortunately I’ve never seen any evidence of infected birds but if you think you may have a problem you can click here for the RSPB advice sheet which has details on how to identify the problem and how best to deal with it.

Returning migrants and lots more besides

Posted on April 23, 2012 | 20 comments

Occasionally, but fairly infrequently, it’s a struggle to find enough interesting nature to put together a post, and then every now and again so much happens that it’s difficult to fit it all in. Last weekend was one of the latter.

It started to get interesting as I was cycling to work on Friday morning, a bird caught my eye in a hedge outside work and first off I thought it was a bullfinch, which I’ve never seen on Cambridge Science Park before. But then I got a better look at it and it was immediately apparent it wasn’t a bullfinch, it had similar colours but in a different pattern, so I did a quick U-turn to get a better look. It turned out to be a black redstart male in full breeding regalia (Phoenicurus ochruros, Dansk: husrødstjert). He was magnificent but alas, because I was heading to work I was camera-less, so if you’ve never seen one, dig out a bird reference book and check him out, it’s worth the effort.

I went back to work on Saturday morning with my camera to see if he was still there but there was no sign of him so I carried on to Milton Country Park, on the northern edge of Cambridge. It was a bright sunny morning and I arrived there just after 8.30 and it was already warm. And it augured well because it turned into a real bird fest. I was hoping to see some returning migrants and as I got out the car I could hear chiffchaff (Phylloscopus collybita, Dansk: gransanger) calling in the trees around the carpark. The first migrant I actually saw was completely unexpected and turned out to be a pair of sand martins (Riparia riparia, Dansk: digesvale) which I haven’t seen for years. There were also swallows (Hirundo rustica, Dansk: land svale) flying low over a lake and this is roughly the same time I saw the first swallow last year. Like swallows, sand martins also over winter in South Africa, but unlike swallows they nest in burrows which they excavate in sandy banks. There are some man made burrows for the sand martins at the country park but so far they’ve been ignored by the martins, but the occassional kingfisher pair have availed themselves of the opportunity.

Close to where the swallow was hunting is a small island with a tree on it where cormorants (Phalacrocorax carbo, Dansk: skarv) can often be seen perched. This time there was a carrion crow (Corvus corone, Dansk: sortkrage) sat on top and a pair of common terns (Sterna hirundo, Dansk: fjordterne) were taking exception to its presence and were working as a team to dive bomb it:

A singleton…

… and in tandem

I almost felt a little sorry for the crow, but I’ve watched them terrorise so many birds, especially buzzards and other birds of prey, in a similar fashion that the sympathy was a tad less enthusiastic than it may otherwise have been.

A migrant which was present all over the country park was the blackcap (Sylvia atricapilla, Dansk: munk), in one bush there were a minimum of four and possibly six or even more. They were squabbling away in the bush presumably in the midst of a territorial dispute. I saw the first blackcap of 2012 a few weeks ago at Danbury Common in Essex during my unsuccessful mission to look for adders.

Blackcap male, the female is similar but easily distinguished because her cap is a rusty brown colour.

As well as the migrants the trees and bushes were full of the song of more familiar resident species such as the robin, blue tit, great tit, blackbird and wren. All were energetically vociferous, filling the air with a wonderful cacophany. And amongst these I caught a tantalising glimpse of a much less common species, the treecreeper (Certhia familiaris, Dansk: træløber). Treecreepers are very aptly named and are fun to watch as they hunt insects in the crevices of tree trunks, spiralling upwards in a corkscrew pattern. A pair of sparrowhawk and a pair of buzzard were also busy performing their aerial courtship routines.

There were none of the winter ducks such as tufted duck (Aythya fuligula, Dansk: troldand), pochard (Aythya ferina, Dansk: taffeland), gadwall (Anas strepera, Dansk: knarand), teal (Anas crecca, Dansk: krikand) or widgeon (Anas penelope, Dansk: pibeand) on the water, they had all headed off north to their breeding grounds. But several birds including coot (Fulica atra, Dansk: blishøne) and greylag geese (Anser anser, Dansk: grågås) had chicks on the water:

Greylag geese with six chicks

I paused to try to get a shot of a great crested grebe (Podiceps cristatus, Dansk: toppet lappedykker), all now in full brown breeding plumage:

And as I stretched over the water, trying hard to get a clean shot of the grebe, and even harder not to pitch headlong into the lake, a grey heron (Ardea cinerea, Dansk: fiskehejre) flew low overhead:

It was so low I thought it must have pitched up very close to where I was but on an adjacent lake, and a quick scan revealed it sat in the top of a tree being pestered by the common tern that had earlier been harrassing the carrion crow:

The terns were deeply unhappy with any potential predator, although they were less keen to buzz a pair of sparrowhawks which were in the air above the same stretch of water!

Animal Rescue

It was Easter last weekend and my parents were visiting. On Saturday I had walked the dog in the fields north of Histon and shortly after entering the field another dog walker told me there was a fox cub (Vulpes vulpes, Dansk: rød ræv) in the undergrowth I had just walked past. So I retraced my steps and sure enough there was this adorable little creature exploring the parapet of the ditch:

It’s body was only 6-7 inches long and I guessed it was the boldest of a litter which had taken the opportunity to wander whilst the mother was out hunting. So I took a few photographs and left it to it’s own devices, and when I completed my loop it was no longer there so I assumed it had returned to the den.

The following day my mother accompanied us for a walk in the hope it was still there, and indeed there it was in exactly the same place, but this time it seemed considerably emboldened and I was extremely concerned that a pet dog may kill it as this was right on a very popular dog walking route. My mother decided that my father should see it and she was going to return and fetch him, so I carried on to walk the dog.

When I got back my mother had been told by someone who lives close by that the vixen had been killed and the cub was orphaned so she rescued it and when I got back it was in a box on top of the piano. Which left me with a dilemma: what does one do with an orphaned fox cub at 4pm on Easter Sunday? It proved to be tricky to find somewhere that took wild animals, so in the end I rang up Wood Green Animal Shelter at Godmanchester, which is only about 12 miles from here, in the hope they would know somewhere that would take the little orphan. And luck was with us, they made some enquiries and gave me the phone number of a lady who lived fairly close by who had reared orphaned fox cubs in the past and was prepared to take ours. So self, mother, the children and the boxed up fox cub were bundled into the car and off we went, and an hour later our little cub was in the hands of someone who was skilled in the art of looking after wild foxes. Result!

It turned out to be a 3-4 week old vixen, who apart from being dehydrated seemed to be in reasonably good shape. She was expected not only to survive but was to be passed on to a wildlife sanctuary for eventual release into the wild. My fingers are crossed that this happens and she has at least one litter of her own cubs. I’m going to try to find out how she does and if I can get an update I’ll let you know.

Turn of the century

Posted on April 6, 2012 | 28 comments

After 20 months of posting this is the 100th episode of The Naturephile. The original plan was to post once a week wherever possible and I’ve averaged around five a month, so that stayed roughly on track. I thought I may struggle to find enough subject material and to acquire sufficient photographs of the necessary quality to post as often as I wanted too, but that hasn’t been a problem, so far.

When I started off writing The Naturephile, the idea I may reach a hundred posts never entered my mind, so to mark the moment I’ve trawled back through the archive to find my favourite posts to give them another airing. I’d anticipated it would be a straightforward venture but of course I’d rather underestimated the amount of subjects/species and photographs I’ve written about. But the number of posts was eventually whittled down to 14.

1) At the end of September 2010 one of natures more brutal rituals was played out right outside my back door involving garden spider courtship. Like other spiders this can easily end up in the death of the male as it did in this case. ‘Araneus diadematus‘ posted on 2nd October 2010:

I really love you… . Male on the left, Shelob on the right

2) A little farther afield are dragon flies, the most common species I encounter are common darters and migrant hawkers. This Common darter appeared in a post on 19th October 2010. I like the symmetry of the fly and the seedhead and the red colour of this male darter against the brown grass.

3) A few years ago when my sister lived in a house (she lives in a kennel now. Only joking, she lives on a narrow boat ;-)) they were digging the garden and this piece of rock turned up. It’s an Acheulian hand axe made from flint and the marks on it are where it was worked with a deer antler. It dates from around 400,000 years ago which means it could have been made by a pre Homo sapiens hominid! It fits beautifully into the palm of my hand and after that many years the edges are still sharp. Even if I was blogging about topiary or book binding I’d have to find a way to slot this in.

4) The winter of 2010/11 was known as a ‘waxwing winter‘. Every winter a few waxwing (Bombycilla garrulus, Dansk: silkehale) migrate to our shores from Scandinavia to overwinter. But occasionally the weather up there is fearsome so the waxwing migrate in large numbers and we then have a ‘waxwing winter’. And I hope you’ll agree the waxwing is a beatiful bird:

A group of waxwing perched at the top of a rowan tree in north Cambridge

5) Another consequence of the bitterly cold winter of 2010/11 was that most stretches of open water were frozen over and our herons (Ardea cinerea, Dansk: fiskehejre) were starving because they couldn’t access their normal food supplies. During this winter a hungry heron appeared in my friends garden and taking pity on its plight he fed it some fish. And of course one fish supper turned into rather more than one so the heron came to expect it, and if dinner was late it came and tapped on the window to complain to the management.

6) Sea mammals of any description are always a delight to see and photograph and one of my favourite places on the planet for doing that is the Farne Isles situated just off the Northumberland coast.

Atlantic grey seal in the North Sea off the Northumberland coast

Our holiday last year was to Northumberland and I can’t go there without taking in a boat trip to the Farnes where hundreds of Atlantic grey seal were basking on the rocks and generally taking life easy in the water.

7) Closer to home, April last year was hot and sunny and a great time to see songbirds in the countryside. One of my favourite birds is the yellowhammer (Emberiza citrinella, Dansk: gulspurv) and they’re regulars in the hedgerows around Cambridge.

Yellowhammer male – what a gorgeous colour!

8) A creature I’d never encountered before last year was the great crested newt. My friend told me of a place where they could be found so we ensconced ourselves in the nearest pub in preparation for a nocturnal newt hunt after closing time.

It was a very successful trip, a few pints followed by finding not only the great crested newt but the other two species of UK newt, palmate and smooth newts.

9) As the year rushes headlong into summer and the butterfly season really gets underway I can spend many an hour chasing our Lepidopterans round the fields trying to get that perfect picture. One of my favourites is the common blue and this is about the closest I got to that perfect picture:

Common blue male sipping nectar – one of the best photographs I’ve ever taken

10) As well as being a top location for marine mammals the Northumberland coast is also home to huge numbers of seabirds so it’s a very happy hunting ground for me!

Just poking your head over the seawall at Seahouses can reveal lots of seabirds including oystercatcher (Haematopus ostralegus, Dansk: strandskade), knot (Calidris canutus, Dansk: islandsk ryle), eider (Somateria mollissima, Dansk: ederfugl), turnstone (Arenaria interpres, Dansk: stenvender) and this redshank (Tringa totanus, Dansk: rødben).

11) RSPB Fowlmere, to the west of Cambridge is famous for its water rail. On a trip there in December 2011 I was tipped off by a local that a particular hide was good for water rail (Rallus aquaticus, Dansk: vandrikse) and one had been seen there that morning, so off I went to try and see it.

My informant was correct. There was just the one bird there, but it scoured the mudflats in front of us for a whole hour before disappearing into the reeds, giving me plenty of good photo opportunities. I was very pleased with the primeval feel of this image with the bird face on infront of the horsetails.

12) In January this year the weather was absolutely freezing causing a small group of red-legged partridge at Tubney Fen, east of Cambridge, to seek the warmth generated by a mountain of dung:

13) My favourite bird of prey is the kestrel (Falco tinnunculus, Dansk: tårnfalk) and they are always to be seen hovering in the skies over the fields around Histon. I love watching the highly specialised hunting techniques all birds of prey in action, but the kestrel beats them all in my opinion:

14) And lastly, I couldn’t write a post like this without including my battling blackbirds. Of all the bird species that visit my garden these are the ones that provide the most entertainment:

These were a few of my favourite posts, favourite for various reasons: the stories attached, the rarity of the sighting or simply the exquisite natural beauty of the subjects. I hope you like them!

And lastly, I’ve been stunned by the numbers of people from all round the world who read The Naturephile and like it enough to follow it or click the ‘Like’ button. Thanks to everyone for stopping by and enjoying a read, I love sharing the nature from my corner of Cambridgeshire with you!

Birds and bee(flie)s

Posted on April 3, 2012 | 20 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:

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.:

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:

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.

Blakes Wood

Posted on April 3, 2012 | 26 comments

In my last post I visited Danbury Common in Essex. After getting over the disappointment of not seeeing snakes we headed to Blakes Wood which is another National Trust site situated on the opposite side of Danbury to the Common. It’s an area of ancient woodland, predominantly hornbeam and sweet chestnut under which the ground was covered in withered chestnut husks emptied of their contents long ago by squirrels or mice, and in the springtime wood anemones (Anemone nemorosa) and bluebells (Hyacinthoides non-scripta) carpet the forest floor.

Bluebells have been voted Britains favourite flower and they normally reach their flowering peak in mid May.

Bluebells are delightful flowers when there is only one plant, but when they stretch across a forest floor as far as the eye can see they’re absolutely magical. I didn’t expect to see any at the weekend, it still being March, but they are starting to flower already.

The Natural History Museum is conducting a survey of bluebell flowering times as a means of monitoring climate change. A quick glance at the data is starting to get alarming, the earliest flowering time seems to be getting earlier, from first flowerings in Essex in May in 2010, moving to the middle of March in 2012, in just three years since the study commenced. I don’t know what the long term ramifications of climate change will be for our native flora and fauna, we’ll have to wait and see but I hope the bluebell woods survive.

The wood anemones are as beautiful as the bluebells even if they don’t have the same level of ‘Wow‘ factor. The forest at Blakes Wood was liberally bespattered with carpets of wood anemones and I got down in the undergrowth to try to fill the frame with flowers:

I was keen to capture a shot with both anemones and bluebells in the same frame and that turned out to be tricky because of the sparsity of the bluebells, but I eventually found this one:

Spanish bluebell bulbs have been sold in garden centres but they are a different species, Hyacinthoides hispanica, to our UK bluebells. Flytipping of garden waste has resulted in the Spanish variety getting into our woods and cross breeding with the native species. This is a real problem because it is anticipated the hybrids may eventually take over from the natives, but I console myself that the invaders and hybrids are lovely to look at too. I can’t wait to visit the woods again in May when the bluebells are in full bloom, and when I do I’ll share the results with you.
