BIRDS OF EASTERN MASSACHUSETTS. 125 
111. Myiarchus crinitns, Cab. — 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 fuscns, Baird. — Phoebe, 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 stomach was com- 
pletely filled with the seeds of the berries of the hawthorn 
{Gratoegiis oxycantha). 
113. Contopns borealis, Baird. — Olive-sided Fly- 
catcher. Not a 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, Cab. — 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. Frequents open woods. 
If the Acadian Flycatcher {Empidonax Acadicus, Baird) 
is found in eastern Massachusetts, I have yet to meet with 
it. I think that this and the following are often confounded 
by collectors, perhaps with good reason. 
115. Smpidonax Traillii, Baird. — TrailVs Fly- 
catcher. Bare in spring ; said to breed, however. I have
