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:

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:

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 way it should be

Posted on July 8, 2013 | 15 comments

My last post showed some random weather at the end of March and in this one all the photographs were taken during the following weekend when the weather was rather more in keeping with the season, the way it should be.

Another of the great British bird of prey success stories over the last two decades has been the resurgence of the buzzard (Buteo buteo, Dansk: musvåge). Up until the mid 1990’s I’d only seen buzzards on summer holidays in Denmark and the occasional sighting on the western periphery of the UK, in south Wales or in Cornwall. But then I noticed they were creeping further eastwards up the M5, year by year, and now they can be seen all over England, and it’s not at all surprising to see them over my garden. I think a major contributory factor to the increase in raptor populations has been the ban on the use of DDT.

DDT, or dichlorodiphenyltrichloroethane…

…was originally extremely effective in the control of insects but is very persistent in the biosphere, and because of its chemical properties it accumulates in the fatty tissues of apex predators such as raptors. The toxic effect was to cause thinning of the eggshells which would break before the chicks were ready to emerge. The consequences were devastating for many species inclusing sparrowhawks in the UK as well as peregrine falcons and bald eagles in the USA. The systematic use of DDT has been outlawed for many years now, although restricted localised use for the control of malaria is still sanctioned, but here in the UK the long term benefit of the ban has been dramatic with these magnificent birds once again a relatively common site in our skies.

Other birds species were making the most of the change in the weather at the start of April too, including this female reed bunting (Emberiza schoeniclus, Dansk: rørspurv):

Reed buntings have been a common site in the fields to the north of Histon since the weather has warmed up and the males with their black and white heads cling to the top of wheat stems proclaiming their availability. The females are more reclusive but can often be seen perched in bushes

A less common visitor to the fields is the golden plover (Pluvialis apricaria, Dansk, hjejle). I love to see the plovers, because when they do arrive they come mob handed, and on this occasion there was a flock of approximately 500 birds which looped round at high speed in extended skeins which was great to watch!

Skeins of golden plovers

Golden plovers are amber listed in the UK but not of concern in Europe so I hope that means that the overall population is stable and we continue to see them over the UK. An amusing little factoid about the golden plover which I’ve unashamedly borrowed from the British Trust for Ornithology is that a question about the flight speed of the golden plover raised by a member of a shoot in Wexford, Ireland, prompted Sir Hugh Beaver to found the Guinness Book of Records in 1955. And if you’re keen to know, the speed of the golden plover is around 60mph (100kmph).

The rook, Corvus frugilegus, Dansk: sibirisk allike

All the photographs in this post were taken during a walk in the fields adjacent to my home the weekend after the snow, except the rook. This miscreant had lifted the fatball feeder from the branch in the crab apple tree and dropped it to the floor where it commenced to single handedly empty it. But as it posed for several portraits in the process I reasoned that it earned it’s fill. I like crows and especially the rooks, they seem to have a sense of devilment akin to a childs… if not even a tad more sophisticated. Through history though, alas not everyone had such a benign attitude to the rook (and just about every other creature!), which you can read about here.
