Add to the gull roost: -
Leaving the 'common' birds for Nick to find.... The rarest bird of the roost.... a Black-headed Gull with partial albino plumage; completely white flight feathers and wing coverts. 2nd only such plumage I have noted in 40 years of gulling !
L B-Backed: Few 100 of both L.f. intermedius and Dutch intergrade 'races'
Yellow-legged: Few 10's
Herring: few 10's
Roost well worth a look; especially if you have a bright Swarovski scope (like Nick); which I do not...damn it !
Also 1 Mipit

ReplyDeleteLeucistic Black-headed Gulls are actually annual at Farmoor, maybe 1 or 2 a year. Mealnistic Black-headed Gulls are the rarity, just two: 2nd March 1993 and 22nd December 1996 (British Birds: Vol 91, page 561).
