Minsmere raptors

Whilst I was at RSPB Minsmere, which I described in my last post, I was expecting to see birds of prey because I know that marsh harriers (Circus aeruginosus, Dansk: rørhøg) nest in the reedbeds there and it wouldn’t be totally unexpected to see a hobby (Falco subbuteo, Dansk: lærkefalk) or a peregrine falcon (Falco peregrinus, Dansk: vandrefalk).

Avocet were nesting on the mudflats along with plenty of other birds including the black headed gulls (Chroicocephalus ridibundus, Dansk: hættemåge):

I was engrossed peering into the distance with my new spotting scope, and I found a spoonbill (Platalea leucorodia, Dansk: skestork). The Danish name translates as ‘spoon stork‘ which just about sums it up really. I didn’t get a photograph because it was too far away, but it looks exactly like a white stork with a long beak shaped like a spoon. The conservation status of the spoonbill is amber and it is extremely rare in the UK and not terribly common on mainland Europe either. According to the British Trust for Ornithology there are 75 individuals in the UK and between 1998 and 2002 there were only 4 breeding pairs.

But I digress. As I was gazing into the disatnce the air raid warning was sounded: “There’s a peregrine… there are two!”

The falcons, I found out subsequently, were nesting on Sizewell B, the nuclear power station adjacent to the reserve. They arrived from that direction and when attacking they appeared to be working in tandem. The speed of their forays was absolutely breathtaking and caused total chaos on the ground:

I tried to capture the falcons in the middle of their attack which was not easy, but I managed to catch one just above the left hand point of the mudflat behind. It wasn’t until I looked at the image at home that I realised the second falcon was in shot on the right too. So even though this photograph won’t win any awards I really like the drama going on here!

The falcons raid lasted for several minutes and I didn’t see them catch any prey, thanks in no small part to the bravery of the common tern (Sterna hirundo, Dansk: fjordterne).

After the excitement of the falcons I ended up in a hide on the edge of the woods overlooking the reedbeds and sure enough the marsh harriers were much in evidence:

… and the male:

Whilst photographing the male marsh harrier a brown shape lifted out of the reeds and someone in the hide identified it as a bittern (Botaurus stellaris, Dansk: rørdrum). It was too fast for me to identify it by myself as I was focussed on the harrier, but that means I heard one booming at Lakenheath in the morning and saw one at Minsmere in the afternoon. Not a bad day out.

I didn’t see a hobby but it would be churlish to dwell on that after the excitement of the peregrines, the family of marsh harriers, and the bittern and spoonbill neither of which I’d previously encountered.

Wicken wheatears.. and some other creatures

The blogging Muse left me in the Spring and I switched to acquisition mode, since when I’ve been out and about taking a lot of photographs. I’ve now got enough images to keep me posting until the end of the year  so I’ve reverted to posting mode and at the same time I’ll be catching up with all my fellow bloggers who I’ve been neglecting for too long!

At the end of April the sunny weather prompted me to take an early morning walk around Wicken Fen. At that time of year fairly large areas of flat pasture immediately adjacent to the fen are flooded and provide habitat for overwintering waterfowl, along with all the other winter visitors and early spring migrants to be found on the Fen. So in good weather at that time of year there’s usually plenty of wildlife. The pasture which isn’t flooded is managed by grazing it with Highland cattle:

I’m no expert on cattle so I don’t know for sure, but because this old guy was on his own and also because of the sheer size of him, I think that he’s a bull (and he didn’t stand up to allow unambiguous gender assignment by an amateur observer). He was absolutely enormous, even laying down I estimate the top of his head was around 5 feet off the ground, he was the size of a car!

Back to the birds though, one which I’ve only seen at reserves on the coast before is the bearded tit (Panurus biarmicus, Dansk: skægmejse), but on this particular morning there was at least two of them flitting around the reed beds between The Mere and Adventurers Fen.

Female bearded tit

I’m yet to get a really good photograph of a bearded tit and this one continues the tradition. It would have been OK but it is too blue because I didn’t have my glasses on when I set the white balance, so I mistook the ‘sun’ setting for the ‘incandescent light’ setting. Alas, an unavoidable consequence of hurtling into middle age! I tried to post process the image but alas I couldn’t get it to look quite right so I decided to leave it as it is and own up to my incompetence!

The bearded tit is a resident breeder and passage/winter visitor and there are only around 600 breeding pairs in the UK, so it’s good to know they are just up the road from where I live. Their conservation status is amber in the UK due to a recent decline in their breeding range but they are not a species of concern in Europe as a whole. They live and breed in reedbeds and feed on invertebrates in the summer and seed in winter.

Another iconic inhabitant of the Wicken reedbeds is the marsh harrier (Circus aeruginosus, Dansk: rørhøg). The colour of the sky reveals the weather on this glorious April morning as a male marsh harrier thermalled overhead. He was in the company of eight others, and that’s an amazing sight.

The marsh harrier frequents reedbeds and marshland and feeds on frogs, insects, reptiles and small vertebrates. Its conservation status is amber in the UK due to its small non-breeding population and a localised breeding population, but as with the bearded tit its not a species of concern in Europe. It almost died out in the UK in the 1960’s but has recovered since then and has changed its behaviour by starting to also nest on farmland, and many individuals now overwinter here too. Those that migrate head down to central and southern Africa for the winter. Another recent raptor success story along with sparrowhawks and red kites, but still a work in porogress to secure the UK population.

Male reed bunting

Small songbirds such as the reed bunting (Emberiza schoeniclus, Dansk: rørspurv) were busy proclaiming their availability from the tops of the hedgerows, but the highlight of the trip was a small group of around half a dozen wheatear (Oenanthe oenanthe, Dansk: stenpikker) feeding in a field adjacent to the Fen as I arrived:

Male wheatear – rear view

The name ‘wheatear’ may derive from the archaic ‘white arse’ which is a local name for it in some parts of England. It’s a migrant breeder in the UK and overwinters in Africa. After the last ice age its range extended northwards with the retreating ice, but they still all migrate back to Africa in the winter, even those individuals that breed in Alaska!

… and from the front

The female is also a striking bird even though she doesn’t have the same slate grey back and black eye stripe that the male does.

The female wheatear

I watched the wheatears for 20 minutes or so before heading on to the Fen and when I returned around 3 hours later they had all gone. So it appears it was an overnight rest and refuelling stop for them before heading further north and west to their summer breeding grounds.

Serendipity I – The Short Eared Owl

Serendipity struck on Sunday a couple of weeks ago. I’d fixed up to go for a stroll with an old friend who I hadn’t seen for a few years to Wicken Fen. That was on the 20th May, but he got his Sundays confused and we ended up going on the 13th.

It was serendipitous because the weather had been grim leading up to that weekend but on the evening of the 13th it was perfect: sunny, warm, calm and we couldn’t have wished for better conditions. And on top of that there was wildlife in abundance. As we got out the car the air was full of swifts screeching overhead – lots and lots of them – along with swallows and house martins. Various species of geese and ducks and great crested grebes (Podiceps cristatus, Dansk: toppet lappedykker) were on the lakes, and we were serenaded by cettis warbler (Cettia cetti, Dansk: cettisanger), grasshopper warbler (Locustella naevia, Dansk: græshoppesanger) and other songbirds in the undergrowth, and a snipe drummed in the reed bed. Snipe (Gallinago gallinago, Dansk: dobbeltbekkasin) make this sound by spreading their tail feathers and the wind generates the piping sound by making them vibrate.

Wicken fen is a really good place to see birds of prey too: marsh harrier (Circus aeruginosus, Dansk: rørhøg), hobby (Falco subbuteo, Dansk: lærkefalk), kestrel (Falco tinunculus, Dansk: tårnfalk), sparrowhawk (Accipiter nisus, Dansk: spurvehøg) and assorted owls can all be seen there. We had been commenting how the birds of prey were conspicuous by their absence and a few minutes later we spotted a hobby perched on a fence post. As we wallowed in our good fortune I spotted an owl behind a tree which emerged right in front of us and it turned out to be a short eared owl:


Short eared owl, Asio flammeus (Dansk: mosehornugle)

I thought our short eared owls were winter visitors, migrating to the relative warmth of the UK from the frozen icefields of Scandinavia and returning in the Spring. But it transpires they are also resident breeders in the east and north of England and the east of Scotland so can be seen here all year round.

This one treated us to several minutes worth of hunting, flying to and fro and diving down into the reeds in search of rodents.

I last saw short eared owls at Burwell Fen, east of Cambridge, several months ago when there was a large number of Scandinavian visitors in residence. While we were there we chatted to a BBC camerman who was there to film them for a TV nature series. I think he would have got some good footage on that day but I’m sure he would have been pleased to get this close to one!

Like all owls, it’s a hunter which is supremely evolved for its particular function.

And then on the journey home, continuing the owl theme, there was a barn owl taking the lazy approach to rodent hunting:

Barn owl numbers have been on the decline for a long time and the exceptionally cold winters of 2009 and 2010 badly affected them. We didn’t see one at Wicken which surprised me because I usually see at least one when I’m there at that time of the evening, so it was good to find this one perched on an advertising hoarding alongside the road home.

I’m a firm believer in serendipity playing her part in human endeavour and she adequately rewarded us on this excursion!

Minsmere in wintertime

My meanderings around Suffolk in February inevitably led me to RSPB Minsmere. I’d heard there were bittern (Botaurus stellaris, Dansk: rørdrum), which I’ve never seen before, and smew (Mergellus albellus, Dansk: lille skallesluger) which I’ve also never seen, in residence there. Indeed, theere had been an influx of bittern from Holland due to the fierce winter weather there and numbers were up, so I felt a little twitching was in order.

For those of you unfamiliar with the geography, Minsmere is characterised by woodland on the inland side to the north and east with a network of reedbeds and lakes behind a sand and shingle bank running along the coast. It lies between Dunwich Heath and the Coastguard Cottages to the north, and Sizewell to the south. It is a haven for numerous species of bird and my friend told me that on a morning trip there with a dawn start he spotted over 100 species of birds by lunchtime. And I reckon that’s an impressive tally. Many mammals also live and visit here including red deer, fox and otter.

As it is an RSPB reserve there are hides for observing the wildlife and as I set off along the bank which forms the sea defences to find one various gulls and great crested grebes (Podiceps cristatus, Dansk: toppet lappedykker) were on the sea. I paused to watch a marsh harrier (Circus aeruginosus, Dansk: rørhøg) quartering the reedbeds, and then headed on to an open hide where I installed myself to see what was in residence.


The view from the south end of the hide

From the lower right hand window of the hide are the reedbeds of the reserve and from the upper left window is the reactor dome of Sizewell nuclear power station. The power station reminds me that I’m very grateful for havens such as Minsmere but I also wonder why on earth does it have to be just there, the juxtaposition offends me somewhat. But there it is, so I contented myself with looking out the front of the hide and here are some of the birds I could see:


A lone lapwing foraging for sustenance

Immediately in front of my hide, in which I was the only occupant, was a water filled channel separated from the lakes just beyond by a thin strip of reeds, and immediately to the fore was a single lapwing (Vanellus vanellus, Dansk vibe). Low grassy islands in the lakes were home to various species of duck, the most numerous being…


Teal, two males and a female (Anas crecca, Dansk: krikand)


Shelduck (Tadorna tadorna, Dansk: gravand), and lurking in the background is a shoveler (Anas clypeata, Dansk: skeand)

All of these ducks are resident or nigrant breeders and winter visitors and where I am I only see them in winter. According to the BTO the teal is unusual in that it has no other names in the UK, which is an interesting little factlet which obviously needs to be challenged. If anyone knows of a local name for the teal please let me know. Another amusing piece of nomenclature is the shoveler, so named presumably for its shovel like beak and in Danish is known as the ‘skeand‘, which translates into English as the ‘spoon duck’. It uses it’s magnificent beak to filter small molluscs and crustaceans from the beds of shallow water by sweeping it across the surface and sifting the food from the disturbed sediment.

Alas, most of the birds were just too far away for my 300mm lens, but I plan to upgrade my optics this year so next time I post from Minsmere I’ll hopefully have lots of high quality close ups too.
