227 (758^). Olive-backed Thrush. Hylocichla ustu- 

 lata swainsoni {Cab.). 



This species is a common transient migrant from May 10 to June 

 ID in spring, passing south in the fall from September 10 to October 5. 



228 (759'^). Hermit Thrush. Hylocichla aonalaschkae 

 pallasii {Cab.). 



A common migrant appearing often as early as March i, and by 

 the end of April the last stragglers have passed northward. The fall 

 migration takes place during October and part of November, but fre- 

 quently one is seen during the winter. (See Scott. Bull. Nutt. Orn. 

 Club, Vol. IV, No. 2, p. 82, April 1879.) 



229(761). American Robin. Merula migratoria (Zz>/«,). 



A very abundant summer resident, and a few winter in secluded 

 places. I am inclined to think that this species is not only becoming 

 more numerous, but is also becoming more familiar. During the spring 

 of 1898, I found sixty-three nests, one of which was in a barn, the re- 

 mainder in trees. 



In 1900, one hundred and seventy nests came under my observa- 

 tion, of which number forty-one were situated in woods, swamps or 

 orchards and one hundred in suitable situations on private places in the 

 town. Of the remaining twenty-nine, eight were placed under bridges, 

 two being under the iron girders of the Pennsylvania Railroad bridge 

 over the Millstone, four were in quarries and sixteen were in barns, 

 sheds, under piazzas, etc. One was found under a board walk, and Mr. 

 D. Miner Rogers found one containing two eggs on the ground at the 

 foot of a bush. Several broods are reared during the summer. The 

 birds are abundant from March 10 to November 20, and a few 

 regularly remain throughtout the winter. 



230 (766). Bluebird. Sialia sialis (Linn.). 



A common summer and not uncommon winter resident. The 

 majority, however, arrive March i to 10, and at once mate and select 

 nesting sites. The eggs are generally laid early in April, and two 

 broods are frequently reared. After breeding, the bluebirds collect in 

 small flocks preparatory to their departure which takes place in 

 November.
