Summer Plumage. Entire head, neck all round, entire lower parts, upper 

 tail coverts and tail pure white ; round the eye an orange red ring ; entire 

 mantle and back, tertiaries and secondaries a delicate pale bluish grey ; the 

 tertiaries and secondaries and longer scapulars broadly tipped with white; the 

 earlier secondaries,"; especially with the major portion of the inner webs, also 

 white ; edge of the wing about the carpal joint white ; primaries, the first with 

 the whole outer wety black, tipped with white and with a broad white band 

 across both webs near the tip ; above this band a considerable portion of the 

 inner web is black, and the rest pale grey ; second primary similar, but the 

 white band often entirely wanting or reduced to a spot on the inner web only, 

 the black on the inner web of less extent than in the first, and the basal por- 

 tion of the outer web the same pale blue grey as the coverts and the rest of 

 the wing ; the third and following primaries have only the white tips and no 

 white band, the outer webs become more grey as they recede from the second, 

 and the black diminishes on the inner webs proportionally, so that on the 

 seventh or eighth it is generally reduced to a narrow black band across both 

 webs, or in some cases on the outer web only, and in others entirely wanting 

 on the last three quills. 



In the winter plumage the nape and back of the neck are striated with pale 

 brown, in some specimens, thinly on the crown also; legs and feet lemon 

 yellow.
