INSECTIVOROUS BIRDS. 
The Tyran ofBuffon, (vol. v. pi. 537,) or Pe pe re, ap- 
proaches near to this species both in size and color, but 
is distinguishable by the bed of yellow on the head, be- 
neath the surface of the feathers. The habits of both are 
very similar. The South American birds live in the soli- 
tude of the forest by pairs, nesting in hollow trees, or in 
the bifurcation of some branch, chanting forth their 
quaint pe pe re, about the break of day, which they an- 
nounce with more precision even than our domestic cock. 
They are likewise very pugnacious in defence of their 
young. Muscicapa barhata of Cayenne, has also some 
affinity with our species, and utters ape pe, or somewhat 
similar note. (Vol. v. p. 277 of the same author.) 
My friend W. Cooper, Esq., so well known for his de- 
votion to Ornithology, received this bird likewise the 
preceding summer from the vicinity of Cape May, and 
Egg-harbour, in New Jersey. The supposed young bird 
of the Crested Fly-catcher, cinereous above and white 
on the belly, mentioned by Pennant, might perhaps 
have been the present species. 
The length of the Olive-Sided Pewee is about 6J to 7 inches. 
Like the rest of the family to which it belongs, it has a blowsy cap or 
crest, erectile at will ; the color of this part is very dark brown, but 
with the hind-head inclined to dark ash, which is the prevailing color 
of the back. The wings and tail are dusky-brown, without any par- 
ticle of white ; the secondaries and their coverts edged with whitish ; 
the second primary longest and the 1st and 3d equal. The tail 
emarginate, extending only about f of an inch beyond the closed 
wings. Bill very broad, nearly J an inch ; rictus bright yellow, as 
well as the inside of the mouth and tongue ; the latter somewhat cor- 
date and bifid at tip ; the upper mandible distinctly carinated, and 
black ; the lower, purplish horn-yellow, lighter towards the base. 
Chin white. The sides dusky olive, a broad line down the middle of 
the breast, with the abdomen and rump yellowish white ; a broadish 
white space on the side, beneath the wing towards the back, extend- 
ing almost to the region of the rump. Legs and feet black, Irids 
dark hazel. This species, though of the size of the King-bird, is near- 
ly related to the Wood Pewee, yet perfectly distinct.
