SMALL GREEN-CRESTED FLYCATCHER. 
squeak, which is heard a considerable way through the woods ; 
and, as it flies from one tree to another, has a low querulous 
note, something like the twitterings of chickens nestling under 
the wings of the hen. On alighting, this sound ceases, and it 
utters its note as before. It arrives from the south about the 
middle of May ; builds on the upper side of a limb, in a low 
swampy part of the woods, and lays five white eggs. It leaves 
us about the beginning of September. It is a rare and very 
solitary bird, always haunting the most gloomy, moist, and 
unfrequented parts of the forest. It feeds on flying insects, 
devours bees, and, in the season of huckle-berries, they form 
the chief part of its food. Its northern migrations extend as 
far as Newfoundland. 
The length of this species is five inches and a half ; breadth, 
nine inches ; the upper parts are of a green olive colour, the 
lower, pale greenish yellow, darkest on the breast ; the wings 
are deep brown, crossed with two bars of yellowish white, and 
a ring of the same surrounds the eye, which is hazel. The 
tail is rounded at the end ; the bill is remarkably flat and broad, 
dark brown above, and flesh colour below ; legs and feet, pale 
ash. The female differs little from the male in colour. 
the wings are much shorter, somewhat rounded, and the comparative pro- 
portion of the quills differ ; the colours, however, nearly agree : the species 
brought home by the expedition was killed at Carlton House in 53° N. lat. 
and it extends southward to Mexico. — T. Richardsonii, closely resembling 
T. fusca ; it differs in the form of the bill, and size of the feet ; the crest is 
thick and lengthened ; the upper plumage is more olive, while the under has 
an olive whitish tint ; the tail is more forked : it was found in the neigh- 
bourhood of Cumberland House, frequenting .moist shady woods by the banks 
of rivers and lakes. 
Mr Audubon also figures a species as new, and dedicates it to Dr Trail, of 
Liverpool ; but, as I have remarked before, it is impossible to decide from a 
plate, however accurate. Tyrannula Trailii will come nearest to the Wood 
Pewee, but differs as well in some parts of the plumage as in the habits. 
It is found in the woods which skirt the prairie lands of the Arkansas 
river — Ed.
