and having the outside webs edged with yellowish green and emarginated 
as far as the fifth. The tail-feathers are brown, the outside webs edged 
with yellowish green, and the inside webs have a narrow greyish-white 
margin. The general colour of the underparts is white, suffused all over 
with yellow, and on the breast and flanks with buff. The axillaries, under 
wing-coverts, and thighs are yellow. Bill dark brown above, slightly 
paler below; legs, feet, and claws brown; irides hazel. In summer 
the upper parts are greyer; in high latitudes occasionally with all the 
yellow and green abraded, leaving the general colour earthy brown, the 
eye-stripe having faded into greyish white. Much of the yellow of the 
underparts also becomes abraded ; and in high latitudes all, except that on 
the axillaries and under wing-coverts, disappears, leaving the buffish yellow 
of the breast and flanks pale grey. The autumn plumage is yellower than 
that of spring. Birds of the year are even more yellow than adults, the 
whole of the underparts being uniform buffish yellow.
