mistake of preceding authors, in asserting that the black 
throat, during the pairing-season, is confined to the male. I 
have invariably found the female to possess it also at that pe- 
riod; but of inferior lustre to that ef the other sex. Its usual 
call is shriller than inthe other species. It displays great 
anxiety when its eggs, or the newly flown young, are disturb- 
ed, and is very vociferous if a hawk, or other enemy, ap- 
proaches the neighbourhood of the nest. 
Puiate 49. Fig. 2. Male bird, in summer-plumage, and of 
the natural size. 
Head and upper parts of the body bluish-grey. Rump General 
bright sulphur-yellow. Above the eyes is a white streak. Cee 
Throat black. Under parts bright gamboge-yellow. 
Wings greyish-black, the coverts tipped with white. 
Tail four inches long; with the outer feather entirely 
white ; the second white, except part of the outer web 
which is black ; the third having an additional streak of 
black on the edge of the inner web; and the remaining 
feathers black, margined near the base with sulphur- 
yellow. 
In autumn the black upon the throat disappears, and is 
succeeded by yellowish-white; and the belly becomes of 
a pale primrose-yellow. The colours of the female, at 
both seasons, are not so bright as those of the male 
bird.
