No. I I Birds of Princeton. 



IQOI J 



Order MACROCHIRES. Goatsuckers, Swifts, Hum- 

 mingbirds, etc. 



Family Caprimulgidse. Nighthawks, Whip-poor- 

 wills, etc. 



92 (417). Whip-poor-will. Antrostomus vociferus 

 {Wils.). 



In the immediate vicinity of Princeton the Whip-poor-will is an un- 

 common summer resident. It is much more frequent, however, in the 

 wooded hills back of Blawenburg where it undoubtedly breeds every 

 year, but as yet there are no records. The birds arrive about April 18 

 and leave about October i. 



93 (420). Night Hawk; Bull-bat. Chordeiles Vir- 



ginian us [Gmel.). 



A not uncommon migrant and rather infrequent summer resident. 

 Professor Phillips found a pair breeding on Mount Lucas May 17. The 

 birds appear about May 4 and leave late in September. 



Family Micropodidae. Swifts. 



94 (423). Chimney Swift. Chaetura pelagica {Linn.). 



An abundant summer resident arriving with regularity the third 

 week in April, departing about the middle of September. The eggs are 

 usually deposited by June 3 and it is very probable that two broods are 

 reared, for young have been found as late as July 22. 



Family Trochilidae. Hummingbirds. 



95 (428). Ruby-throated Humming Bird. Trochilus 



colubris Linn. 



A common summer resident remaining from late in April until the 

 middle of September. Several nests which I have seen contained eggs 

 the first week in June.
