CRESTED FLYCATCHER. 413 
The Olive-sided Flycatcher is a rare summer resident in the 
southern portions of New England, but is quite common in 
Maine and New Brunswick, and ranges north to about the soth 
parallel. In the region of the Great Lakes it occurs but rarely. 
CRESTED FLYCATCHER. 
MYIARCHUS CRINITUS. 
Cuar. Upper parts olive, inclined to brown on the head; lower parts 
bright yellow, excepting throat and cheek, which are dark ash; wings and 
tail dusky, marked with rufous. Head crested. Length 8% to g inches. 
Nest. Ina cavity of a tree; of twigs, grass-roots, feathers, and usually 
a cast-off snake-skin. 
Leggs. 4-6; light buffy brown, marked with lines of brown and purple; 
0.85 X 0.65. 
This species, nearly unknown in New England, arrives in 
Pennsylvania early in May, and builds his nest in the deserted 
holes of the Woodpecker or Bluebird. He also frequents the 
orchard, and is equally fond of bees with the Kingbird. He 
has no other note than a harsh squeak, which sounds like 'paip, 
"paip, payitp, ‘paywep, with a strong accent on the first syl- 
lable. He preys actively on insects, which he collects from 
his stand, and, in short, has most of the manners and _physi- 
ognomy of the whole section or family to which he belongs. 
The note of the male appears often delivered in anger and 
impatience, and he defends his retreat from the access of all 
other birds with the tyrannic insolence characteristic of the 
Kingbird. 
Towards the end of summer these birds feed on berries of 
various kinds, being particularly partial to pokeberries and 
whortleberries, which for a time seem to constitute the prin- 
cipal food of the young. They remain in Pennsylvania till about 
the middle of September, when they retire to tropical America. 
In July, 1831, I observed a pair in an orchard at Acton, in this 
State (Massachusetts). They had reared a brood in the vicinity, 
and still appeared very stationary on the premises; their harsh
