BIRDS OF EASTERN MASSACHUSETTS. 125 



111. Myiarchus crinitUS, CAB. Great Crested Fit/- 

 catcher. Very rare summer resident. Have taken it on 

 May 9th and 15th. Said to breed. Frequents the open 

 woods. 



112. Sayornis ftlSCUS, 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, 1858, I shot one whose stomach was com- 

 pletely filled with the seeds of the berries of the hawthorn 

 ( Cratceg >/s oxycantha ). 



113. Contopus 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. 



1 1 4. Contopus virens, CAB. Wood Pewee. Com- 

 mon summer resident. Arrives from May 19th to 28th; 

 leaver early in September. Breeds. The nest is composed 

 of moss, and is placed on the top of some high limb, and 

 reseinbbs a protuberance upon it ; for this reason it is 

 not easily detected. Frequents open woods. 



If tho Acadian Flycatcher (Empidonax Acadicns, Baird) 

 is found in eastern Massachusetts, I have yet to meet with 

 it. 1 think that this and the following are often confounded 

 by collectors, perhaps with good reason. 



1 1 5. Empidonax Traillii, BAIRD. TrailCs Fly- 

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