BIRDS OF EASTERN MASSACHUSETTS. 125 



111. Myiarchus crinitus, 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 fuscus, BATED. -- 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 

 (Cratcegus oxycantha). 



113. Contopus boreaHs, 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. Empidonax Traillii, BAIRD. Traill's Fly- 

 catcher. Hare in spring ; said to breed, however. I have
