Today we had the first major arrival of redpolls at Revtangen BO. In between the 171 Mealies there were a few Coues's Arctic Redpolls. Adult male (top) and 1 cy. Polarsisik.

Bullfinches can easily be aged as 1 cy when the outer greater coverts are shorter and with buffish tips, as in the top photo of todays female where the five outer greater coverts are juvenile. The male in the lower photo is an adult with all gc of adult type. More important is the clour on the outer webs of the carpal covert - the short single covert between the greater coverts and the alula (white arrow). Notice the brown outer webs in the 1cy in the top photo, and compare with the greyish outer webs in the adult-type carpal covert in the lower photo. Some 1 cy birds have moulted all greater coverts, but not the carpal covert.

Observations: Grey Wagtail 10, Mealy Redpoll 500.
