SYLVIA CELATA. 
the crest are orange at base, constituting a spot on the 
crown, visible only when they are elevated, being 
tipped with the common colour. The whole bird 
beneath is dull olive yellow; the inferior tail-coverts 
are pure yellow. The wings are destitute of spots or 
bands; the primaries are dark brown, olive green on 
the exterior margin, which is much paler on the outer 
ones ; the interior margin is whitish ; the four outer 
primaries are subequal; the fifth is but very little 
shorter. The tail is even, the feathers being dark 
brown, edged with olive green on the outer, and with 
white on the inner web. 
The orange-crowned warbler resembles several species 
of indigenous and foreign warblers ; and the females of 
others, such as that of the Sylvia trichas , may also be 
mistaken for it ; but it may be distinguished from each 
of them respectively, by particular characters, which it 
is not necessary to detail, as the concealed orange spot 
of the crown is a peculiarity not possessed by either 
of the allied species. The Nashville warbler ( Sylvia 
rubricapilla ) of Wilson, seems to be more closely related 
to the orange-crowned warbler than any other. That 
bird, also, is evidently a Dacnis , and scarcely differs 
from our species, except in the white belly, the light 
ash colour of the head and neck, and the deep chestnut 
colour disposed in small touches on the crown, instead 
of an uniform orange colour. The only difference 
observable between the sexes is, that the rump of the 
male is of a brighter colour, approaching, in old birds, 
to a pure yellow. 
During winter, the orange-crowned warbler is one 
of the most common birds in the neighbourhood of 
St Augustin, Florida, almost exclusively frequenting 
the orange trees. Their manners resemble those of 
the kindred species, though they have a remarkable 
habit of constantly inflecting the tail, like the pewee. 
The note consists of a chuck, and a faint squeak, but 
little louder than that of a mouse.
