BIRDS OF EASTERN MASSACHUSETTS. 125 
111. Myiarchus crinitus, Cas. — Great Crested Fly- 
catcher. Very rare summer resident. Have taken it on 
May 9th and 15th. Said to breed. Frequents the open 
woods. 
112. Sayornis fuscus, Batrp. — Phebe, Pewee. Com- 
mon summer resident. Arrives from March 25th to April 
12th. Have taken it as late as October 9th. Nests in 
barns, under bridges, and under some projecting rock of a 
ledge; in the spring it may be found in the neighborhood 
of these localities, but it occurs everywhere in autumn. 
Although a strictly insectivorous bird, yet, when compelled 
by hunger, it can be granivorous; during a violent snow- 
storm, April 2, 1868, I shot one whose stomacn was com- 
pletely filled with the seeds of the berries of the hawthorn 
(Crateegus oxycantha). 
113. Contopus borealis, Barrp. — Olive-sided Fly- 
catcher. Nota very rare summer resident. Breeds. “ Nests 
generally in the fork of a pine-tree; the only nest that I 
ever found that was not placed in this situation was on the 
outer limb of an apple-tree.”* Frequents the open wood. 
Arrives from May 12th to 24th; leaves early in Sep- 
tember. 
114. Contopus virens, Cas. — Wood Pewee. Com- 
mon summer resident. Arrives from May 19th to 28th ; 
leaves early in September. Breeds. The nest is composed 
of moss, and is placed on the top of some high limb, and 
resembles a protuberance upon it; for this reason it is 
not easily detected. Irequents open woods. 
If the Acadian Flycatcher (Hmpidonax Acadicus, Baird) 
is found in castern Massachusetts, I have yet to meet with 
it. IL think that this and the following are often confounded 
by collectors, perhaps with good reason, 
115. Empidonax Traiilii, Bairp. — Traill’s Fly- 
catcher, are in spring; said to breed, however. IJ have
