Greenland Wheatears

Big Day Count for Spring

73 Icelandic/ Greenland Wheatears plumages counted yesterday. Stunning plumage, especially on the males. Here 2 males (wing lengths 106 and 107mm) and a female (101mm). I came up with a working hypothesis years ago that ‘Greenland-type’ birds with their longer wings, also had often more visible primary tips on the closed wing. I thought maybe 6 -7 tips visible on the nominate form and 7-8 tips visible in Greenland birds. Does it work?

anyway in celebration of ‘North-western’ Wheatears:

and an almost/ maybe acredula Willow Warbler:
