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 figure given in our plate is that of a male; and 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.

For this very interesting new species, ornithology is again 
indebted to Long’s Expedition, and particularly to Say, who 
gave it the name we have adopted, and informs us, in his 
notes, that many of these birds were shot in the month of
