PALM WARBLER. 
Ill 
the head are dusky at base, as is the whole plumage ; 
then they are chestnut nearly to the tip, (forming a 
concealed spot of that colour on the crown,) where 
they are of the common colour, but somewhat darker ; 
the rump and superior tail-coverts are yellow olive ; a 
well defined yellowish white line passes over the eye, 
which is encircled with white ; the cheeks are dusky, 
as well as a streak through the eye ; the inferior parts 
are whitish, slightly tinged with yellowish, and with a 
few blackish streaks on each side of the throat, and on 
the breast and flanks ; the belly is immaculate, and more 
richly tinged with yellow, the inferior tail-coverts 
being pure yellow ; the wing-coverts are of the colour 
of the feathers of the back, the blackish centre being 
more extended and deeper ; the w ings have no bands ; 
the quill feathers are blackish, edged externally with 
pale yellow olive, becoming w hitish towards the tip ; 
the five outer ones are subeqnal ; the tail is even, its 
feathers are somewhat pointed, edged externally with 
yellow olive, internally with whitish, the outer one 
also externally whitish; the tw r o outer ones with a 
large pure white spot on their inner vane at tip ; the 
third and fourth, each side, with an inner white ter- 
minal margin. 
In this plumage, this bird resembles so nearly Sylvia 
coronata in its most humble dress, that it it distinguish- 
able only on a close examination. However, the bill 
is longer, and more slender, the crown spot chestnut 
instead of yellow, the feathers being destitute of the 
white which is observable in the other, by separating 
the feathers ; the rump is olive yellow, not pure yellow, 
and that colour extending on the tail-coverts, which it 
does not in Sylvia coronata . The under parts tinged 
with yellow, and especially the pure yellow tail-coverts, 
which are pure wdiite in S, coronata , will sufficiently 
distinguish them. 
It is a remarkable circumstance, that there is no 
obvious difference to be observed betw r een the plumage 
of the sexes, notwithstanding the statements of authors 
to the contrary. This is the case, however, in S»
