More bird diversity from RSPB Titchwell

Posted on May 29, 2023 | Leave a comment

RSPB Titchwell has a ‘linear’ layout encompassing various habitats and that make it a good place to see a diverse range of bird species. Following on from my last post here are few more waders, wildfowl and geese that were in residence when I was last there in November last year.

Shoveler pair – Spatula clypeata

The shoveler inhabits shallow lakes and marshland where there is open water and it can be seen all year round in the UK. It breeds in the UK before heading south for the winter when the breeding population is replaced by visitors migrating south from Scandinavia and eastern Europe. The size of the UK breeding population is around 1100 pairs.

Brent geese – Branta bernicla

The distribution of brent geese in the UK is interesting because their are three separate overwintering groups which migrate here to the UK. They come from Canada, Svalbard and Russia and overwinter primarily in Strangford Lough in Ulster, Lindisfarne in the UK and the rest of the UK respectively. There are 100-110,000 birds recorded annually in the UK but in the case of the Canadian and Svalbard visitors it’s easy to see how human activity could profoundly affect those very local populations. As these individuals were seen in Norfolk I guess they from the Russian cohort.

A flock of lapwing – Vanellus vanellus and golden plover – Pluvialis apricaria

Golden plover have a distinctive black face and breast stretching down to its legs in the summer but which fades to pale brown to white in the winter so the birds in this group all have their winter plumage which I would expect as this was in mid-November. The golden plover is resident all year in the UK with 33,000 breeding pairs in 2016 according the BTO and 410,000 individuals recorded in the winter of 2006-7 as the population swells in autumn as migrants arrive from the north.

The lapwing is for me an iconic bird and a sign of summer and I remember seeing big flocks of them over the farmland close to where I grew up in Northamptonshire. It’s now rare to see such flocks inland although I still see mixed flocks of lapwing and golden plover over the Cambridgeshire fens in the winter time. And that is refected in this mixed flock on the ground at Titchwell and it’s interesting to see the species separation on the ground.

RSPB Titchwell is a great place for a day out to see lots of wildlife in summer and winter. There is always something wonderful to see including migrants at the right times of year and I consider myself very lucky to live close enough to it to be able to make day trips there.

Coastal waders at Titchwell Marsh

Posted on May 8, 2023 | 1 comment

RSPB Titchwell Marsh is a reserve I’ve posted about several times before and it’s a great place to get close to a lot of bird species. It’s on the north Norfolk coast and it includes various habitats from woodland scrub to fresh water lakes, reedbeds, salt marsh and the BIG beaches that make that part of the country so spectacular. It’s home to bearded tits, which I didn’t see on this visit in November last year, but I saw many other species of goose, duck, wader etc.

The increasingly elusive curlew – Numenius arquata

The curlew is Europe’s biggest wader, with it’s very long downturned beak and distinctive call it’s easy to recognise. Alas, as with so many other species it’s endangered in the UK with big losses in numbers, approximately 80% decline in the last 50 years or so, due to habitat loss. The east coast of the UK is a globally important feeding and overwintering station for migrating birds, and there’s increasing realisation of the importance of protecting it as climate change threatens to encroach and flood low lying coastal areas. To mitigate against that, there are initiatives underway in East Anglia to allow the sea to reclaim tidal land which will provide a buffer against the potentially catastrophic flooding that rising sea levels could bring, as well as providing huge amounts of habitat for the creatures that rely on these tidal mudflats. I hope that projects like the one to create habitat using the spoil from the London Crossrail development at Wallasea Island in Essex will help to redress the balance and enable stabilisaton and even increases in populations of the visitors that rely on it for sustenance during their arduous journeys.

Another wader which was present in numbers at Titchwell was the bar tailed godwit:

Bar tailed godwit – Limosa lapponica – showing it’s magnificently long beak

The bar tailed godwit, like the curlew, is also one of the bigger waders with a very long beak, but in the case of the godwit the beak isn’t curved downwards and it has a pink root extending a long way along it’s length. The tip of a godwits beak is also prehensile, enabling it to better find it’s prey of shellfish, snails and worms buried deep in the mud of it’s coastal habitat. They breed in the summer in the high Arctic and head south in the autumn to feeding grounds that include the UK coasts and the British Trust for Ornithology estimate a population of 30,000 individuals.

The bar tailed godwit is an amazing bird and in 2020 a youngster broke the record for the longest recorded non-stop flight when it migrated from Alaska to New Zealand in one hop – a flight of approximately 12,200km (7,625 miles)! It’s well adapted for long distance travel, with long, pointed wings and the ability to store a lot of energy and the whole journey took 11 days at speeds up to 88km/hr (55mph). It’s a phenomenal feat of endurance and navigation.

A very welcome return

Posted on May 1, 2023 | 2 comments

When I was a kid and we holidayed every year in Denmark, the stork was an iconic bird and one we never saw in the UK, and we would take trips down to Ribe in southern Jylland – the Danish mainland – to see storks nesting on church towers, thatched rooves and wagon wheels the locals had mounted on tall poles for that purpose.

In recent years a successful reintroduction program undertaken on the Knepp estate in Sussex with birds from Warsaw zoo has resulted in storks breeding again in England. The last recorded breeding in the UK happened in 1416 so it’s been a very long time coming!

Yesterday I went for a walk around Burwell Fen and Wicken Fen and the spring weather was perfect for nature watching; and birds, butteflies and mammals were out in abundance. But the star of the show was a stork sitting atop the Tower Hide at Wicken Fen. I’d been tipped off by another person enjoying a walk in the spring sunshine that it was there, but I was a tad sceptical until I rounded the bend and there it was. The first time I’d seen one outside Denmark or central Europe. Suffice to say I was beside myself.

White stork – Ciconia ciconia – perched on the Tower Hide at Wicken Fen in Cambridgeshire

The stork is a migrant to Europe after overwintering in Africa and is up to 1.1m tall with a wingspan of around 1.8m. It’s a big bird and nests in small colonies on spectacular nests made out of sticks and I hope they start building them in Cambridgeshire again in the not too distant future.

I’d deliberately left my camera in the car to just enjoy the scenery and of course I half regretted that, so I took these images with my phone. Not the best quality photo’s of a stork but I’m very pleased with them and they record a very special sighting for me.

After taking flight from the hide it soared higher and higher over the Fen for probably 10-15 minutes or so before disappearing.

Apart from the stork, the Fens were alive with othe creatures and even though I don’t like lists this time it’s worth sharing a selection of what I saw and heard:

Hare, roe deer, orange tip butterflies, peacock (butterflies), speckled wood, brimstone, oystercatcher, lapwing, shelduck, swift (the first I’ve seen – and heard – this year), swallow, kestrel, sparrowhawk, marsh harrier, hobby, peregrine falcon, buzzard, cetti’s warbler, sedge warbler, grasshopper warbler – and all of these whilst being constantly serenaded by wrens and cuckoos.

If only I’d taken my camera 🙂

Owl Outing to Burwell Fen

Posted on April 10, 2023 | Leave a comment

The short eared owl is resident in northern England and Scotland where breeding populations reside, but in my part of East Anglia,near Cambridge, they are only seen in winter time when migrants from Scandinavia arrive.

A really good place to see short eared owls is Burwell Fen a few miles to the east of Cambridge. it’s a wide open scrubby space bordered by farmland and by Wicken Fen which is managed by the National trust and is itself an important nature reserve.

I went there with some friends who hadn’t seen a short eared owl before and were excited at the possibility, and as with all things natural, even though I was reasonably confident we would see one, there’s never any certainty. We met up there one afternoon in early January and within 5-10 minutes one appeared hunting over the grassland.

Short eared owl – Asio flammeus – quartering the Fen

I don’t know if the cattle that were grazing the Fen were flushing the voles that the owls feed on but this one seemed to be spending a lot of time hunting around the cattle.

One owl taking exception to a second one encroaching into it’s space

As we watched over the Fen for the next couple of hours at least 3-4 owls were in the air, and here’s photographic evidence that were at least two!

It was a bright sunny winter afternoon in January and because of the time of year the sun was low in the sky all day and the light was spectacular. It lit up the Fen, which can appear grey and featureless on a cloudy winter day, in gorgeous pink and orange hues. It was beautiful to look at but challenging to photograph! And before the sun sunk below the horizon a barn owl also appeared to hunt small rodents.

A ghostly barn owl – Tyto alba – appeared just before dusk, the night shift replacing the day shift

And shortly after the sun sunk below the horizon in a polychromatic blaze of colour…

By now it was too dark to see the wildlife, and too cold to linger, but it had been a wonderful introduction to the Fen and to short eared owls for my friends!

Butterflies on the Beacon

Posted on March 24, 2023 | Leave a comment

One hot sunny day in late spring last year I headed over to Ivinghoe Beacon in the Chiltern Hills in Buckinghamshire because it’s renowned as a stronghold of the rare Duke of Burgundy fritillary butterfly. As I’d never seen one before and I love butterflies this ticked some boxes for me. I parked a mile or so away from the beacon and was greeted by a whitethroat perched on a tangle of power cables, it was a nice start to a nice outing.

It was a mile or so across fields and up the hill onto the beacon but it was well worth the walk. The views from the top are huge and it didn’t disappoint on the butterfly front either. The first one was a brown argus soaking up the sunlight on a grass stem

Brown argus, Aricia agestis

I think this one is a female from the prominence of the orange spots which are bigger and more pronounced in the female. The brown argus could be confused with a common blue female but the brown argus is smaller and the blue has a noticable blue hue at the wing roots.

The brown argus lives primarily on chalk grassland and feeds on various species of cranesbill:

Dovesfoot cranesbill – a food source for brown argus caterpillars

There were many species of butterfly patrolling the scrub and grassland on the beacon looking for plants to feed on and lay eggs on including this gorgeous brimstone caught probing for nectar in a cowslip. The male brimstones are more yellow than the females which are pale and more green so I think this one is a male.

Brimstone butterfly, Gonepteryx rhamni

The sulphurous brimstone is another buttefly that is happiest around scrubby grassland and is active through May and June, so with the fine weather I wasn’t surprised to see them on the Beacon.

Another species which was abundant was the green hairstreak. These butterflies are an amazing colour and quite unmistakable

Green hairstreak, Callophrys rubi

Even against a sumptuous green background the irridescent greenness of the hairstreak stands out at a distance. It’s a smallish buttefly with a wingspan of around 30mm or so but it’s not difficult to spot, and the adult is active from mid April into July. It’s not terribly fussy about the habitat it frequents or the soil type so I hope that will help to ensure its survival whilst many other butterfly species are in spiralling decline due to habitat destruction and climate change. Basically, because of us, people.

But the star of the show that I’d headed across country to see was the Duke of Burgundy. I didn’t have to wait very long and after seeing one there were lots of them. Mission accomplished.

The Duke isn’t a very large butterfly, also with a wingspan of approximatelty 30mm, but the colours are exquisite:

Duke of Burgundy, Hamearis lucina

Because of the prominent position to display I think this one is probably a male as the females are more elusive and spend a lot of time looking for suitable egg laying sites. The underside of the Duke is even more colourful than the upper:

The Duke of Burgundy, like so many of our native butterflies is in peril and only survives in a small number of locations in southern England and two in the north, one in the southern Lake District and the other on the North Yorkshire Moors. So even though I had to drive for an hour to see them it was a pretty special trip and it didn’t seem that far!

A few days ago I went for a walk in the city centre of Cambridge and as luck would have it it was a day when the grounds of Trinity College were open to the public. I crossed the river Cam over the Garret Hostel Bridge by Trinity Hall and looped back through Trinity College to recross the river over Trinity College Bridge.

***From Trinity College Bridge looking back to Garret Hostel Bridge***

It was a beautiful warm sunny morning and it’s a very green part of the city, and the grounds of the ‘backs’ of the colleges are surrounded by drainage channels, so on a day like that I’d expect there to be lots mini beasts buzzing around over the water and feeding on all the open flowers.

**Drainage channel between Trinity Hall and Trinity College**

With so much water lined with uncultivated banks adjacent to other areas which had been cultivated to maximise the number of flowers it should have been humming with bugs and and the birds that feed on them.

***Flower beds and gardens of Trinity College***

It’s a lovely place to spend time on a sunny morning but the almost total lack of insects was worrying. Along the drainage channel above I saw no insects at all and in the flower beds and gardens of Trinity I counted three butterflies – two small whites (I think), one holly blue – and two bumble bees. There was also very little birdlife apart from half a dozen jackdaws that were flapping around the lawns.

There have been a lot of news articles in recent times about how climate change is causing a catastrophic decline in insect numbers, and there seems to be debate about what’s really going on; but the almost total absence of them on a sunny morning in somewhere as green as the ‘Backs’ in Cambridge made me think that there is a problem here.

**St Johns College from the gardens of Trinity College**

It’s a beautiful place but maybe not as green and biodiverse as I thought it might be. Or should be.

Fenland floods

Posted on April 24, 2022 | 2 comments

Because the land is very flat to the north of Cambridge there is a lot of infrastructure to deal with flooding and that includes extensive flood relief around Earith. A couple of weekends ago there were lots of waders and ducks making the most of the flood waters there including black tailed godwit and blue winged teal (Spatula discors), an unusual visitor from north America.

**A flock of black tailed godwit (*Limosa limosa*)**

The birds were too far away to photograph individuals but we estimated there were 2-300 in total. There were many other birds on the water and mixed in with this group were teal (Anas crecca), redshank (Tringa totanus) and the ubiquitous black headed gulls (Chroicocephalus ridibundus). We didn’t see the blue winged teal but the regular teal, shoveller, redshank and godwit more than made up for that.

Right at the start of the walk there were two coot nests, one was being sat on and the other was in the final stages of construction.

**Female coot (*Fulica atra*) busily building her nest platform above the water**

And whilst the female was occupied with home making, the male was otherwise engaged defending his territory and squaring up to another male:

Unfortunately all this mating activity was to no avail, on the same walk a week later the flood water had receded and both the coot nesting sites were left high and dry and were deserted. But there is a huge area here which is suitable breeding habitat for coots so hopefully they found somewhere a tad more permanent

It was a bright and sunny spring morning and the route was regularly punctuated by the song of chiffchaffs which could be seen flitting around the trees. And then this little chap popped up right in front of us on a bramble just a few feet away

**Chiffchaff (*Phylloscopus collybita*) posing for a portrai**t

The chiffchaff has a distinctive song from which it gets its name and is one of the first migrant warblers to arrive back in the UK from its winter feeding grounds in north Africa. It can be heard as early as late February and at this time of year there are many of them singing in the tree tops.

Springtime Fenland birdlife

Posted on June 8, 2020 | 4 comments

After my last post, my long time blogging friend, Scott, mentioned in a comment that he was reading a book set in my part of the world, viz the fenland of East Anglia. And that reminded me that during the Covid lockdown we’ve beeen allowed to drive a few miles to exercise outdoors, and back in April I ventured over to a local fen for a walk with my camera.

The Fens are a unique ecosystem characterised by lakes, reed beds and low scrub which create habitat for a wide range of wildlife and they’re a great place to see flowers, birds, mammals and reptiles. It was a glorious sunny day when I was there and the wildlife was abundant, including this male reed bunting who posed beautifully for his portrait:

Reed bunting Ouse Fen 18 Apr 2020_3015 Reed bunting (Dansk – Rørspurv, Latin – Emberiza schoeniclus)

Cuckoos (Dansk – gøg, Latin – Cuculus canorus) were cuckoo’ing all around the Fen – it’s apparently a good year for cuckoos here in the UK, and I heard one for the first time ever in the village a few weeks ago – and bittern (Dansk – rørdrum, Latin – Botaurus stellaris) were booming. The bittern is a smallish brown heron which lives and breeds in reedbeds and is extremely rare in the UK, only 191 males were recorded in the UK by the British Trust for Ornithology (BTO) in 2017. Their booming call is an amazing sound and it can carry for over a kilometre. It’s difficult to find a recording that really does it justice but if you click on the link this one hopefully gives you a good idea of what they sound like. Even though when they boom they’re very disticntive and easy to hear, they’re not easy to see unless in flight as they blend in perfectly with the background of the reedbeds. But one of these days I hope I can post one of my own pictures of a bittern to show you.

However, one bird that is easy to see is the marsh harrier:

Marsh harrier Ouse Fen 18 Apr 2020_3040 Marsh harrier (Dansk – Rørhøg , Latin – Circus aeruginosus)

The marsh harrier is another one of the British birds of prey whose numbers have recovered significantly since the 1960’s presumably after the pesticide DDT was banned, and this one is a male hunting small mammals or birds over the low scrub of the fen.

The marsh harrier is a constant on the Fen, and it seems the bittern may be coming one too, which is fantastic. But the cuckoo isn’t, they’ve laid their eggs for the host species to rear and will soon be heading back on the perilous journey to the rainforests of sub-Saharan west Africa, hopefully to return to the UK next year to fill the spring air with their wonderfully distinctive call.

Avian relaxation

Posted on May 24, 2020 | 4 comments

Following on from my last post when I mentioned the changes in behaviour of the local wildlife, since then there have been more birds relaxing in the garden. There have always been wood pigeons (Columba palumbus) round and about, and for several years they’ve nested in my plum tree in the front garden, but this year, in the absence of most of the normal human intrusion, they’ve been omnipresent. There are often at least two sitting atop the garden wall just relaxing,

Growing on the garden wall is a wisteria, and you can see the purple flowers here. But what you can’t do is smell the flowers.

49871189203_d73b7ff92f_c

On a hot sunny day, for a couple of weeks in early May, the bracts of flowers, which are up to a metre long, fill the garden with the most intense and heavenly aroma. Interestingly though, the bees don’t seem to be that bothered by it, but I love it!

What I think are a pair of males have adopted a branch in the apple tree which they fight over – I assume they’re males, if they’re females I imagine they’d probably just take it easy and have a chat, but I guess it’s that time of year.

But a few days ago this one dropped down out the apple tree onto the grass and after lazily mooching about for a few minutes just hunkered down and did nothing for 20-30 minutes or so:

49930145537_6c4790cfeb_b Cooling off on the ground, and obviously not afraid of the local cats

He wasn’t sufficiently relaxed to doze off like the dove in my last post and he stayed alert, but even so, I’ve never seen one do this before.

Lockdown Upside

Posted on May 8, 2020 | 3 comments

I’ve been working from home during these unprecentedly loopy times we’re all living through. So while I’m sitting reading next to the window I’ve noticed the local wildlife has been behaving quite differently. The creatures frequenting my garden seem much more realxed than they normally do. I have a resident wren which I’ve seen hunkering down to sunbath just outside the window, and that’s unusual. Other birds that would normally flit in and out really quickly have also been taking their time, such as this collared dove which took time to enjoy the sunshine and generally take it easy yesterday.

First off it perched on the back of a garden chair and had a really good stretch, wings extended and tail fanned:

49871710901_d00183dca1_z

And after spending quite a few minutes just hanging around and enjoying the heat it drifted off for a little siesta…

49871180628_575a45753c_c

And that would never have happened before the Covid-19 lockdown. So even though it’s a pain for humans, it’s wonderful that the rest of the creatures on the planet can enjoy a few months of quality relaxation whilst we’re not terrorising them.
