The Winter Change of Plumage of the Black Guillemot.— 
Years ago, when I spent my winters North, I had specimens of the Black 
Guillemot (Uria grylle) sent me in midwinter in full dark summer 
plumage. I was inclined to think some did not change into light plumage, 
but from specimens sent me this winter I find that the change is very 
early, and some are in full summer plumage by the 1st of February. One 
specimen, shot the first week in February, had but few light feathers. 
This winter change appears different from the fall moult, when the bird loses 
all his pinion-feathers, so that it cannot fly, since in winter the feathers 
appear to change from white to black without much of a moult. — George
