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.

A very welcome return

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 🙂

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!

The fragile nature of Green Belt

Posted on April 23, 2019 | 2 comments

Over the last year and a half or so I’ve been working with a group of people from my village to try to limit the development of our Green Belt land. ‘Green Belt‘ is undeveloped green space encircling built up areas which has legal protection from development in order to limit urban sprawl and provide places where people from towns and cities can go for relaxation.

One of our areas slated for development is Buxhall Farm, which is around 300m from where I live. It’s in the Green Belt and I’ve posted about it’s wildlife on numerous occasions. On the face of it it’s a flat and boring piece of arable farmland with little value for wildlife. Or so you might think. Closer inspection shows that it’s home to many species of birds as well as wildflowers, butterflies moths, mammals etc. All you have to do is look…

Linnet (Linaria cannabina, Dansk: tornirisk)

All the picures here were taken on Buxhall Farm over the Easter weekend from 19th to the 22nd April and at the end of this post is a full list of my sightings there from that weekend.

The linnet is a ‘red listed’ bird in the UK which means it’s of maximum conservation concern. This listing is usually due to falling numbers which is often the result of habitat destruction. Linnet are present at Buxhall all year round and breed there.

Dunnock (Prunella modularis, Dansk: jernspurv)

The dunnock isn’t red listed… yet. It’s a common sight round here and it has a rather lovely song, and some interesting mating habits.

Skylark (Alauda arvensis, Dansk: sanglærke)

The skylark is red listed due to declining numbers, largely due to intensive farming methods. I spoke to the farmer earlier in the week and he told me that he leaves wide field margins to encourage the wildlife and farms his land accordingly. So hats off to him, it shows that it’s possible to make a living from the land without destroying all the wildlife.

Female reed bunting (Emberiza schoeniclus, Dansk: rørspurv)

Yellowhammer (Emberiza citrinella, Dansk: gulspurv)

Over the last three winters there have been flocks of around 50 yellowhammers (also red listed) at Buxhall Farm and this is an important number of these lovely birds. They are one of those iconic farmland/hedgerow species whose numbers have plummeted in recent decades, also due to intensive farming methods, but we still have a healthy population in my neck of the woods.

Peacock butterfly (Inachis io)

All in all I saw at least 7 species of butterfly. There were many whites, but only one species that I could identify as it flew close and slow, but there were probably large whites and green veined whites too, both of which I see there every year. Butterflies are a very good indicator of the health of a habitat so to see so many species so early in the season was wonderful.

Long tailed tit (Aegithalos caudatus, Dansk: halemajse)

Long tailed tits are normally fliting from tree to tree in small flocks but this time there were only two and they seemed local to a particular tree, suggesting they’re a breeding pair using it as a nest site.

Small tortoiseshell butterfly (Aglais urticae)

Goldfinch (Carduelis carduelis, Dansk: stillits)

Land designated ‘Green Belt’ has historically not been developed to retain those green areas for local people to get away from the city. But under current planning legislation an authority can simply take land out of Green Belt and develop it as it pleases. Combined with the massive curtailment of funding from central government to local authorities there’s now intense financial pressure for those authorities to try to develop an income stream from the land they own. It’s perfectly understandable that cash strapped councils need to raise funds but I don’t think this is a good way to do it, but it’s what’s happening around my village and what we are trying to minimise.

The full list of sightings on Buxhall Farm between 19th-22nd April 2019:

It’s a really great place for wildlife and I hope we can help to ensure it remains as very well managed farmland and doesn’t get destroyed by developers building houses.

More Rainham wildlife

Posted on December 27, 2016 | 8 comments

The terrain at Rainham Marshes is fairly varied with beach, river, lakes, reedbeds, scrub and grassland amidst the industrial conurbation of the Thames Estuary. And with varied terrain comes varied birdlife including wader, ducks, birds of prey and passerines:

A lone black tailed godwit (Limosa limosa, Dansk: stor kobber-sneppe) amongst a group of teal (Anas crecca, Dansk: krikand) at the lakeside with reedbeds in the background

As well as godwit a small flock of lapwing (Vanellus vanellus, Dansk: vibe) would occasionally lift of the ground as an alarm was raised over some perceived threat, circle around for a minute or two before returning to where they were flushed from. I’ve seen that kind of behaviour before in response to the sighting of a predator such as a peregrine falcon, but I didn’t see any predators of that ilk so maybe an unseen ground predator such as a fox was in the vicinity.

And across another section of reedbed was the raised Eurostar train track and a transport depot full of trucks just beyond

And I love this image of another stonechat craning from the top of a bulrush to keep a wary eye on what we were up to:

We had heard a report that at the far end of the reserve toward the landfill hill there were short eared owls in the area, and later on in the afternoon we decided to wander down that way to see if we could find them. And it didn’t take long…

Short eared owl (Asio flammeus, Dansk: mosehornugle) patrolling the reedbeds

And that heralded the start of probably the best display of owl activity of any species that I’ve ever seen. And I’ll post some more shorty pictures next time. But isn’t this guy a beauty?!

Rainham Marshes

Posted on November 11, 2016 | 10 comments

Normally when I head out into the wilds I like to get to somewhere where there is little or no evidence of humans, my benchmark for a good place is the complete absence of human noise. And that’s not usually easy to do. But on this trip back in December I found myself in a place that was everything I’d normally avoid!

A view across the marshes to the hill in the background which is an enormous landfill site, full of Londan’s waste

I was at the RSPB reserve at Rainham Marshes which is in that part of estuary Essex I’d only normally visit if I had to, but apart from that it was bordered by industry on one side, landfill on another, a motorway and the Eurostar trainline on the third side and the River Thames providing the boundary on the fourth, southern, edge. But despite my original prejudice it turned out to be a brilliant place to see some great wildlife and bizarrely it was actually enhanced by the hubbub going on all around.

Stonechat (Saxicola rubicola, Dansk: sortstrubet bynkefugl)

On entering the reserve, just beyond the visitor centre a male stonechat was perched on a twig close by, and I like stonechats – they’re very smart birds – so I took it as a good omen that I would see lots more wildlife. And the little guy was indeed a harbinger of things to come. Despite its green conservation status and being a resident in the UK, I don’t see stonechats very often, so I was pleased to see this one so close by.

The terrain at Rainham is interesting. It’s a combination of marshy reedbeds, small lakes, grassy scrub and in the middle is a disused military shooting range which I think dates back to the world wars. But altogether it’s a little oasis of wilderness in the midst of the industrial devastation that dominates this part of the Thames estuary to the east of London.

Reeds, wigeon, lake, lapwing and in the distance a marsh harrier perched on a fence with an oil storage facility in the background

The marsh harrier (Circus aeruginosus, Dansk: rørhøg) is a magnificent bird of prey which I see fairly frequently as they quarter the low lying fenland that prevails to the north and east of Cambridge and the occasional one drifts through over the fields where I live, and here was a female showing her prominent golden crown, hunting over the marshes at Rainham. This species of harrier is another bird of prey which was virtually driven to extinction in the UK but has recovered in the last 40 years, presumably as the use of DDT ceased. And in the foreground on the island in the lake were wigeon (Anas penelope, Dansk: pibeand), lapwing (Vanellus vanellus, Dansk vibe) an unidentified gull and what I think may be starlings.

The lapwing take flight in front of a pair of huge wind turbines

May be there were so many species and numbers here because they were hemmed in to a small area of suitable habitat, but further east along the estuary, deeper into Essex, there are huge areas of tidal mudflats on the Thames and other river estuaries, so this could be the western extremes of that expanse of habitat. Either way, the diversity of the birdlife here on the marshes was remarkable.

A male shoveller looking resplendent and with that enormous beak to the fore

I said further back up this post that the southern boundary of the reserve is the river Thames, and to make the point, beyond the dyke which provided protection from the coastal tides of the river, a ship headed out to sea…

It really is a diverse and fascinating place! And somewhere I’m hoping to visit again before the winter is over.

The amazing potential of phone photography

Posted on October 10, 2016 | 16 comments

A few weeks ago, in August, I was in Toronto and on a glorious sunny day I took a boat trip out to Centre Island, which, in the unlikely event you ever find yourself in Toronto wondering what to do, I can heartily recommend. There were many huge and colourful butterflies including monarchs and swallowtails fluttering around the island, and some others I didn’t recognise. It was a work trip so I hadn’t taken my DSLR with me and the only way to get a photograph was with my phone camera. And then I discovered that monarchs are skittish and it’s not easy to get close to them, which I needed to do as I only had a phone to take pictures with, but after chasing several and failing to get within range I managed to sneak up on this one:

monarch-toronto-aug-2016-pp Monarch butterfly – Danaus plexippus

I stooped down on the opposite side of the plant to the butterfly and reached around to point my phone and take this picture. I must confess, I was a little gobsmacked at how well it worked. The light conditions were challenging as it was late morning and the sunlight was intense, so there was lots of contrast between the shade and the light. But after minimal post processing to darken the sunny bits I think is a pretty good image! I changed my phone earlier this year for an iPhone 6S plus and I was impressed with the quality of the camera from the start, but after this shot I’m really impressed with it.

I hope it’s not a global phenomenon, but this year, due to climatic aberrations, many butterfly species have been hit really hard and their numbers have plummeted. The results of the ‘Big Butterfly Count‘, an annual survey of our Lepidoptera here in the UK, was reported today, and the news was bleak. Many erstwhile common species have really suffered and this is a phenomenon which I’ve noticed and commented on several times since the Spring this year. And now it’s official. Sir David Attenborough (the worlds greatest living human being), and president of the charity Butterfly Conservation, said that butterflies are a good barometer of the state of nature in general. I’m inclined to agree with him and I think it’s a very bad sign that the plight of our butterflies in the UK is so dire. It doesn’t augur well.

small-copper-wandlebury-roman-road-sep2016-pp Small copper – Lycaena phlaeas

But one of my absolute favourite butterflies, and one that I only see very infrequently, even in a good year, is the small copper. I think they’re gorgeous. I haven’t seen one for about three years and then, randomly, a friend of mine showed me this picture a couple of weeks ago which he took with his phone, also an iPhone 6S, on the Roman road between Cambridge and Linton.

So there are still some lovely butterflies out there, but please think of them and, if you can spare it, leave a little bit of your garden to grow wild with no chemicals to help them recover. And if you don’t have a camera handy to take a portrait give it a go with your phone instead, you might be surprised!

Conder Green

Posted on September 9, 2016 | 10 comments

A few weeks after the outing to Norfolk I wrote about in the last few posts, I found myself in a place called Conder Green, which lies on a small tributary of the River Lune in Lancashire, with Morecambe Bay to the west and the Lake District to the north east. I stayed in a hotel which was on the Lancaster Canal and surrounded by farmland, and there was lots of wildlife in the immediate vicinity.

Little egret at dusk on the Glasson Branch of the Lancaster Canal (Egretta garzetta, Dansk: silkehejre)

The little egret, or indeed egrets in general, were birds I had always associated with more exotic parts of the world. The first time I saw them in numbers they were perched on fish stalls in the market at Victoria, the capital of the Seychelles. Their numbers have been steadily increasing in England after they first began to colonise here in 1988 having moved across the water from France, where they had also been expanding their range northwards. But to see one in Lancashire reminded how far north and west they have migrated compared to the location of my first sighting!

Moorhen (Gallinula chloropus, Dansk: grønbenet rørhøne)

Goldeneye female on the Lancaster Canal (Bucephela clangula, Dansk: hvinand)

The moorhen and the goldeneye were on the canal adjacent to my hotel, and in the field next to that was a hare which appeared at first sight remarkably unfazed by my presence, until I got just a little too close, and then common sense prevailed and it did what hares do best, and ran:

The European brown hare (Lepus europaeus)

I was pretty happy with these two shots, I’ve previously got some good pictures of hares by creeping up on them very slowly when they’re sitting tight, but I’ve never got a good picture of a hare in full flight before.

The hare is a member of a taxonomic group called ‘Lagomorphs‘ along with rabbits and pikas. It’s a group that has been around for 90 million years, so hare-like creatures may have been running around with dinosaurs. The modern version evolved in central Europe but only since the UK split away, geologically that is, from mainland Europe. So it is thought that it was introduced to these islands around 2000 years ago by the Romans.

Wigeon (Anas penelope, Dansk: pibeand)

Just a short walk from the field where the hare was is the River Lune, which appears to be tidal as it’s so close to the coast of Morecambe Bay, so when the tide’s out there are extensive mudflats for waders and ducks including these wigeon, and I’ve also seen teal and curlew here:

Curlew (Numenius arquata, Dansk: storspove)

This bird, with its unfeasibly enormous beak, was one of a flock of around 100 curlew, and that’s an extremely unusual sight these days.

All those flocking waders…

Posted on April 6, 2016 | 11 comments

A couple of posts ago I wrote about the vast flocks of geese which overwinter on The Wash; and there were also big numbers of other birds including small groups of dunlin close in by the shore:

Dunlin (Calidris alpina, Dansk: almindelig ryle)

But a little further out, and almost invisible until they took to the air, were enormous flocks of thousands of dunlin. I couldn’t see what flushed them, but every few minutes they rose en masse and put on a stunning display of aerobatic prowess:

Thousands of dunlin moving in very close proximity at high speed and never colliding

Occasionally they turned into the sun creating a shimmering ribbon of grey and white across the sky:

And as with the geese in the previous post the other thing which I hadn’t thought about until they were swirling overhead was the noise. It was a very different sound to the geese which gave a slow muted beating sound, the dunlin sounded more like a fast moving cloud of enormous insects. It was a really exciting spectacle. And as well as the dunlin flocks of oystercatcher wheeled over from behind and landed in a line on the mud flats:

Several hundred oystercatchers (Haematopus ostralegus, Dansk: Strandskade) seeking safety in numbers

… and it’s always good, but increasingly seldom, to see flocks of lapwing (Vanellus vanellus, Dansk: vibe):

When I was a kid in the 70’s vast flocks of lapwing were a relatively frequent phenomenon in the fields out in the countryside around home, but their numbers have plummeted twixt now and then, so it’s good to see there are still places where thay can still be found doing what lapwing should be doing!

Winter in the Wash

Posted on March 31, 2016 | 8 comments

One of the ‘must see‘ natural events in the UK occurs in the winter when hundreds of thousands of ducks, waders and, in particular, geese spend the season on the mudflats of the Wash. The Wash is a huge bay on the east coast of England into which the rivers Witham, Welland, Nene and Great Ouse all drain into the North Sea.

When the tide recedes, like Morecambe Bay in the previous post, enormous areas of mudflats are exposed which provide sustenance and a roost site for colossal numbers of birds. Every morning at dawn thousands of geese take flight to head inland to feed, and the geese are what everyone goes there to see.

Multiple skeins of pink footed geese at Snettisham at dawn (Anser brachyrhynchus, Dansk: kortnæbbet gås)

I arrived at the coast at Snettisham on the north Norfolk coast around 6am when it was just starting to get light. Already sizable flocks of geese were in the air and I was concerned that I’d missed most of them. But then as the sun rose higher gargantuan flocks started to pass overhead and it was a truly incredible sight!

I don’t know how many thousands of geese were there but at the end of the day I went back to the same place to see them return. It was getting dark and all was still, so, as in the morning, I thought I’d missed them. And then they appeared, quite suddenly in their tens of thousands. I tried to estimate the numbers by counting small numbers of each wave and multiplying up, and I estimated there were between 30-40,000 birds returning.

Skeins within skeins, I like this formation

And if you’ve ever spent any time near geese you’ll know that they’re not afraid to announce their presence, so the other thing that I hadn’t expected, but maybe I should have done, was the noise. It was a magnificent cacophony! And not just the squawking, but the sound of them flying when they came over lower to the ground.

These birds breed in the summer up in the Arctic, in Greenland, Iceland and Spitsbergen and then head south to the relatively balmy conditions of the UK coast in winter (!).

Another skein of pink footed geese passing low overhead

It’s unknown why geese fly in skeins, but it’s thought to provide an aerodynamic advantage to the ones behind as they slipstream in turbulent air generated by the bird in front. Which makes me wonder if they constantly switch the pacemaker or if the biggest and strongest bird is always the one at the front.

I estimated there were around 500 birds in this huge flock, but even that was a tiny proportion of the total

To see this meant getting up and out at 4am which is never my favourite thing to do, and it was ferociously cold, but it was worth it to see such a unique spectacle. And as the sun rose and it got lighter, it soon became apparent that the geese weren’t the only seabirds in the area:

A shelduck (Tadorna tadorna, Dansk: gravand) on final approach past a lone dunlin in the foreground

Small flocks of shelduck and dunlin were mingling and feeding close in to the shore

The Wash is now not the only significant area of coastal mudflat in East Anglia. In order to attempt to mitigate some of the anticipated ravages of climate change, flood defences protecting areas of farmland on the coast further south in Essex have been deliberately breached. This has allowed the land to be reclaimed by the sea and to regenerate the tidal mudflats that were there before humans originally interfered. The new habitat was created with the millions of tons of earth removed the ground under London in order to build the Crossrail tube train tunnels. And as soon as this happened the wildlife started to recolonise, and even though it is still fairly barren in comparison to established habitat, I hope that in the near future it will also provide refuge to hundreds of thousands more birds, and lots of other wildlife too.

Dunlin (Calidris alpina, Dansk: almindelig ryle)
