More Fenland birding

Having spent a couple of evenings watching Starling murmurations with hundreds of thousands of birds, it was time to seek out some Aves in smaller numbers. I had a quick look in at RSPB Ouse Fen (Earith) as it was bright and sunny on Saturday morning. I was hoping to that there would be a chance that the Cranes would be showing. They weren’t but there was a Great White Egret, as ever, and a Chinese Water Deer, I had only fleeting, distant views of a solitary Marsh Harrier. I headed out to Chain Corner to check on the Whooper Swans, a few on the water and one that flew right over me.

Next on to a patch of flooded farmland, often used for fen skating historically, it had lots of waterfowl, but no Glossy Ibis there this year, despite their having bred not far from here in 2023. Then on to RSPB Berry Fen, which is just a short hop further up the road. Chiffchaff calling, lots of Widgeon whistling but no Black-tailed Godwit, there were several hundred earlier last week, apparently.

There was also a distant piping Redshank and the Merlin app picked up the sound of a Green-winged Teal (it’s perhaps the same American vagrant we’ve seen here over the last two or three years; previously, there has also been a Blue-winged Teal). There had also been Dunlin and similar species there but I couldn’t see them. There was a Sparrowhawk, known affectionately as a Sprawk to birders, that flew right over me and away with its familiar flap-flap-glide flight pattern.

Further round, the flood, a group of Greylag Geese hanging out with some Russian visitors – three White-fronted Geese. This species, Anser albifrons, might better be known as “white-faced” as you can see from the photos. But as is often the wont of naturalists names sometimes don’t quite match the species description.

According to the BTO website: Two races of White-fronted Goose occur in the UK. A. albifrons (the European WfG) breeds in western Russia and is usually about 1000 to 2000 of them are found in the south and east of England in the winter. A. flavirostris breeds in western Greenland (the Greenland WfG) and about 10000-12000 of this subspecies usually spend the winter in the north and west of Britain and Ireland.
