A day at the coast today, to see some lingering rarities, and to find some c-ringed gulls. No luck with the Black-throated thrush, but the rest of the birds were more cooperative. I started with a Rough-legged buzzard Buteo lagopus near Oostende, followed by 3 Pale-bellied brent geese Branta bernicla hrota, a nice flock of 12 Greater scaup Aythya marila, a Horned grebe Podiceps auritus, a very nice adult Black brant Branta bernicla nigricans (only the 3rd Belgian record), another Rough-legged buzzard, and finally also one of the wintering White-tailed eagles Haliaeetus albicilla.
I could also read 10 c-rings today, of which 4 were new. Best birds were a Danish Black-headed gull, a new Norwegian Greater black-backed gull and a French Lesser black-backed gull. The other rings were 6 Belgian Herrings and the regular British Herring white A3MM.
