Fenland floods

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.

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.

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

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

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:

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_3040Marsh 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.

The Common Crane

A couple of weeks a go I was on an early morning train heading out across the Fens near March in Cambridgeshire where I saw a group of 30-40 cranes in a field next to the train line. I’ve only ever had one fleeting glimpse of a common crane in the UK before so it was properly exciting to see such a large group of these statuesque birds. So much so that two days later I drove to the vicinity of the first sighting to see if I could find them again. And after a little driving around this is what happened…

14 common cranes (Grus grus, Dansk: trane)

These 14 birds were part of a group of 19 that flew right overhead and it was a quite incredible sight! According to the BTO the common crane is amber listed after being hunted to extinction four centuries ago. It has recolonised East Anglia naturally since 1979 and according to the Weekly News from BirdGuides a record 54 pairs of an estimated 180 birds were counted this year in the UK.


After this sighting I headed on to the Ouse Washes where this group formed part of a larger group of 40-45 birds, so I saw approximately a quarter of the UK population. They were too far away to get a photograph but captivating to watch in the distance through binoculars. They were a mile or so off to the left and straight in front, several miles away, was Ely Cathedral:

Which even though it was made by humans is also a majestic site on a sunny morning across the flat expanse of the Fens.

The great grey shrike

Back in January there was a report of a great grey shrike at Wicken Fen and I’d never seen one before so I decided to go and have a look.

It was a very grey morning and not really one of those that gives me high hopes of seeing much wildlife, but the shrike put in the very briefest of appearances, probably less than 2 seconds, so short I couldn’t photograph it, but it was a striking bird! It was bigger and paler than I thought, and with its piratical black eye stripe it was completely unmistakeable. And despite my initial pessimism there was lots of birdlife around that morning.

Fieldfare (Turdus pilaris, Dansk: sjagger)

The Tower Hide at Wicken Fen is usually a good place to survey the area and see the local birdlife, and as the shrike had appeared very close to it I climbed the stairs to see if it would reappear and pose for a portrait. Unfortunately it didn’t, but all the following pictures are from the top of the Tower Hide:

Redwing (Turdus iliacus, Dansk: vindrossel)

The redwing and the fieldfare are winter visitors in the UK, making the flight here from Scandinavia as the weather turns cold there for the winter.

This male bullfinch may have appeared a little more washed out than he actually was. Or he may have been a youngster or waiting for some warmer weather to change into his sumptuous breeding regalia.

Long tailed tit (Aegithalos caudatus, Dansk: halemajse)

And finally…

A kestrel (Falco tinnunculus,Dansk: tårnfalk)

The drops of condensate clinging to the twigs around the kestrel give a fair indication of the prevailing weather – it was very cold… and very damp!

The frozen Fen

The winter frost finally arrived in my corner of Cambridgeshire in the last week and it left the landscape with a thick coating of pure crystalline whiteness. So I was able to indulge my recently discovered fascination with more abstract nature photography:

My trip out to Burwell Fen, east of Cambridge, early last Saturday morning was spectacular as a result of the frosty weather. I set off with my friend, David, around 8am with a view to catching some more sightings of short eared owls, and at that time the temperature was well below freezing. But it was one of those beautiful misty mornings where the mist is thin and lets through lots of light but the density waxed and waned, creating constantly changing, ghostly conditions. Which is lovely to look at but not so good for finding wildlife.

As we approached the Fen, driving out the back of Reach through Tubney Fen (which, incidentally, has had nesting avocet in previous years), roe deer and red-legged partridge were in abundance (no exaggeration!) . I like partridge and I see them quite often around Histon, but I usually flush them before I can get close enough to photograph them, but on this instance the car made a great hide.

Red-legged partridge (Alectoris rufa, Dansk: rødhøne) were introduced to England from Europe and alas for them they are a game bird.

Roe deer (Capreolus capreolus) were also much in evidence, we counted 43, and at one point on the Fen they were flushed and moved en masse and we counted 31. I don’t think I’ve ever seen that many in one go and it was a terrific sight. We think the four below were part of a family of five, the fifth just out of shot. The big one on the right is the female, the horned one in the middle is the male and the other two are youngsters, the third youngster is the one out of shot.

Muntjac deer tracks

Roe deer are native to the UK but muntjac, also known as the barking deer, were introduced from China to Woburn in Befordshire where escapes and releases, and their obvious liking for the Home Counties led to a rapid expansion of their population. I regularly see and hear them in Histon, and the barking sound they make is quite unlike anything likely to be heard in the English countryside.

Whilst scanning for owl, I spotted a stonechat in the grass (Saxicola torquatus, Dansk: Sortstrubet bynkefugl):


Male stonechat

The stonechat is a resident breeder and a migrant to the UK and frequents the kind of scrubby countryside found on Burwell Fen.

Then when the mist lifted and the morning developed into a very cold but very sunny one, the owls appeared, and we had lots of sightings. We chatted to a BBC camera man in the car park who had come to film the short eared owls and he must have captured some good footage by the time he went home.

They are great to watch, they hunt low over the scrub for rodents and regularly get chased up in the air by crows and on one occasion, a kestrel.


Short eared owl

Short eard owls (Asio flammeus, Dansk: mosehornugle) have a small breeding population in the UK, but also migrate here in the winter from northern Europe. I’ve heard that they are here in larger numbers than normal this year due to last year being a good lemming year in Scandinavia. Whatever the reason I’ve heard a number of reports of sizeable groups in Essex, Cambridgeshire and Northamptonshire. They are diurnal and therefore easier to see than most owls and they are very distinctive. The underside is largely white, the winspan is around a metre and the pale brown spot toward the end of the top of the wing is also easy to see and differentiate them. They also have bright yellow eyes which I’ve heard is characteristic of owls which hunt in daylight – but I’ve not found any hard evidence for that.

Lastly, we had several encounters with this group of nine grey partridge, also known as the English partridge (Perdix perdix, Dansk: agerhøne). The numbers of our own partridge have plummeted catastrophically in recent decades, by up to 90%. I see the occasional one around Histon, but it was good to see this group on the Fen.

The red/brown head and lack of white face, black eye stripe and white wing markings clearly distinguish the grey from the red-legged partridge. The difference in demeanour was remarkable, the red-legs seemed relatively unfazed by our presence and were easy to see and photograph, but the greys sat tight, very low to the ground, and flew away at the slightest disturbance.

In one trip we saw all the UK partridge species, and lots of short eared owls, and more roe deer than I’ve ever seen before in one go. Well worth the early start on a freezing morning!

All those flocking waders

The Cambridgeshire Fens can be a bleak and windswept part of the world as the winter months descend, and today it was very bleak and very windswept, but it’s a great location for getting out and seeing some exciting and scarce wildlife.


A small flock of lapwing and golden plover over Burwell Fen

For those of you who don’t know the Fens they’re characterised by wide open flatness and big skies. They were originally under water but were drained by Dutch engineers in the 17th and 18th centuries to leave high quality arable land. The soil is extremely rich in organic material which gives the soil the rich black colour evident in the picture above.

I set off there on Saturday with my friend David because there had been a report on the Cambridge Bird Club website of short eared owls (Asio flammeus, Dansk: mosehornugle) in the vicinity. After wending our way through Swaffham Prior and Reach we rocked up at Tubney Fen where we sat in a new National Trust hide overlooking a new pond with new reed beds which had four coots (Aythya fuligula, Dansk: blishøne) and a pair of mute swans (Cygnus olor, Dansk: knopsvane) paddling on it. And no other signs of life whatsoever.

As we watched, the mute swans took off and looped round low right in front of us and landed back on the water. At least one of them landed on the water in the spectacular and graceful way that mute swans do. The other one crash landed on the ground just short of the water and after regaining its equilibrium stood looking highly indignant but managed to retain it’s dignity in a way that only a mute swan could in those circumstances. We hoped it wasn’t injured but it looked to be suffering from little more than damaged pride.

After another five minutes sat in the hide the lack of further activity and the low temperature caused us to move on, and on the way back to the car we spotted eight whooper swans in a field several hundred meters away. The whooper (Cygnus cygnus, Dansk: sangsvane) is a winter migrant to the UK and a very scarce breeder, usually less than ten pairs a year will breed here. It’s a similar size to the mute swan but it’s neck is straighter and the beak is straight with a black tip and pale yellow base. Their breeding territory is in the high Arctic and they migrate south as far as Africa for the winter.

We decided to move on to Burwell Fen from Tubney Fen and on the way we were considerably closer to the swans so we stopped for another look. And as we looked David noticed that a pale brown stripe in an adjacent field was in fact a flock of golden plovers (Pluvialis apricaria, Dansk: hjejle) and lapwings (Vanellus vanellus, Dansk:  vibe). When I was a kid I spent a fair amount of time out and about exploring the countryside and huge flocks of lapwing consisting of hundreds and possibly thousands of birds were a fairly common sight. But their numbers have been dwindling for decades and these days I’m pleased if I see more than twenty. A carrion crow was getting agitated in the tree beyond the plovers because a buzzard (Buteo buteo, Dansk: musvåge) was perched there too, but the crow wouldn’t get too close and the buzzard just sat tight and ignored it. There turned out to be 243 lapwing in this flock and for me that alone justified the trip.


Around 10% of the lapwing in our flock of 243

There were also several hundred golden plover. As we watched another even bigger flock joined them and when they were flushed into the air we could see another flock as big again in the middle distance and beyond that another that was enormous. So we estimated that between these flocks there were several thousand birds. It was a amazing sight.

The flocks of waders eventually settled so we made off further into the Fen, pausing to gaze at a group of roe deer (Capreolus capreolus) relaxing in a field:


These very well camouflaged roe deer didn’t seem at all perturbed by our presence

As we watched the deer, a sparrowhawk (Accipiter nisus, Dansk: spurvehøg) quartered the field and then a peregrine falcon (Falco peregrinus, Dansk: vandrefalk) swooped past car, travelling with the customary haste that species is renowned for.

Arriving eventually at a car park, we continued on foot over a bridge where several kestrels (Falco tinnunculus, Dansk: tårnfalk) were quartering all the fields around and almost immediately spotted a short eared owl. It was perched on a fence post in the middle of the adjacent field and I initially mistook it for a little owl because I was looking at it from front-on and I could only see the top half, but when we saw it through David’s spotting scope we could clearly see it was of the short eared variety.

As a result of the inclement weather, low light and strong wind, and only having a 300mm lens I couldn’t get any good photographs, but it’s unmistakeably a short eared owl, so I’m happy.

We saw various small songbirds such as chaffinch (Fringilla coelebs,  Dansk: bogfinke) and goldfinch (Carduelis carduelis, Dansk: stillits), five bird of prey species, whooper swans, and countless thousands of golden plover and lapwing. So despite the cold it was fine way to spend a Saturday morning.
