in appearance to its near allies, it often escapes attention when by no 

 means uncommon. It passes through this part of New Jersey during 

 the latter part of May and returns about September 5, remaining some 

 two weeks. I am obliged to Mr. Scott for this data. 



107 (467). Least Flycatcher. Empidonax minimus 

 Baird. 



Mr. Witmer Stone, in his ^Birds of Eastern Pennsylvania and New 

 Jersey, calls this species " a rare breeder in this latitude." From ray 

 own observations here during the past four years, I should call it a tol- 

 erably common summer resident. Five nests have come under my ob- 

 servation, of which two are at present in my collection, so it is by no 

 means rare in the breeding season. Mr. Scott and Prof. Phillips have 

 also found nests. The eggs are generally laid about May 25. The 

 birds arrive about April 25 and leave by September 15. 



Family Alaudidse. Larks. 



108 (474). Horned Lark. Otocoris alpestris {Linn.). 



Dr. Farr tells me that this species is common during the winter 

 months at Cranbury. At Princeton it is a rather irregular fall and win- 

 ter visitant, though sometimes common, frequenting the bare pastures 

 and old corn fields back of the town, from September 10 until March 25. 



Family Corvidse. Crows, Jays, etc. 



109 (477). Blue Jay. Cyanocitta cristata {Linn.). 



A not uncommon resident, but more frequently seen during the 

 colder months, when they congregate in bands. At the approach of 

 spring, the jays seem to disappear and retire to the most secluded places 

 to breed. The eggs are generally laid about the first week in May in 

 this locality. 



110(488). American Crow. Corvus americanusy^z/^. 



At Princeton the crow is an abundant resident throughout the year, 

 but much more so during the colder months. It is very probable that 

 those breeding here winter further south. During the fall, a great num-
