184 THE BIRDS 
One of our latest migrants to arrive, April 30th to May 
5th, and one of the latest to breed. Unlike most of the 
other breeding migrants, nest building: is not commenced 
soon after arrival, often a month passing hy before eggs 
are deposited. Truly a woodland bird, few can mistake 
it after once hearing its plaintive ‘‘Pee-wee.” The 
warmer the day the more he enjoys sitting on some limb 
overhanging the road or field, and uttering his plaintive 
eall, flitting back and forth from one perch to another, 
catching insects. The low nest is saddled on the limb of 
some tree, preferably with moss or lichens on it, and as 
the outside of the nest is covered with lichens, detection 
is not readily made. Old orchard trees are a favorite 
site, as well as for the Blue-gray Gnateatcher. Two or 
three eges is a full set here; the nest being composed of fine 
grasses, lichens and bits of moss, covered on the outside 
completely with lichens and spiderwebs, or plant fiber. The 
egos are like most of the flycatchers,’ a rich cream color, 
spotted and blotched with reddish-brown and lilac, mostly 
on the larger end in the form of a wreath. Size, .80x.55. 
The height of nesting site varies from ten to forty feet. 
Only one brood a season. Fresh eges June 5th to 20th, 
They are a most useful bird, as various species of flies 
(including the house fly), bugs, beetles, moths, cater- 
pillars, grasshoppers and spiders are eaten by them. 
They should be rigidly protected on account of their 
benefit to the agriculturist. They leave us on their south- 
ward migration about September 25th.
