BLUE-GRAY FLYCATCHER. 
est branches, and is seldom seen among the humbler thickets. 
It remains with us until the twentieth or twenty-eighth of Sep- 
tember, after which we see no more of it until the succeeding 
spring. I observed this bird near Savannah, in Georgia, early 
in March; but it does not winter even in the southern parts of 
that state. 
The length of this species is four inches and a half, extent six 
and a half; front and line over the eye black; bill black, very 
slender, overhanging at the tip, notched, broad, and furnished 
with bristles at the base; the colour of the plumage above is 
a light bluish gray, bluest on the head, below bluish white; tail 
longer than the body, a little rounded and black, except the 
exterior feathers, which are almost all white, and the next two 
also tipt with white; tail coverts black; wings brownish black, 
some of the secondaries next the body edged with white; legs 
extremely slender, about three-fourths of an inch long, and of a 
bluish black colour. The female is distinguished by wanting 
the black line round the front. 
The food of this bird is small winged insects and their larvae, 
but particularly the former, which it seems almost always in 
pursuit of.
