throated Green does, — usually the second week in 

 May, — and is commonly observed in Connecticut or 

 Massachusetts until June, by which time most indi- 

 viduals betake themselves northward. The return 

 movement occupies the month of September and part 

 of October, as in the case of the species last men- 

 tioned. There is even an instance of the presence of 

 the bird near Boston in winter ; but this is of course 

 wholly exceptional. The chief difference in habits 

 between this species and its nearest relative is, that 

 it does not show the same decided preference for 

 pineries. 



The best account we have of the nest and eggs is 

 that lately furnished by the Rev. C. M. Jones, who 

 twice found these birds breeding at Eastford, Conn., 

 and recorded his observations in the Bulletin of the 

 Nuttall Club, i, Apr., 1876, p. 11, as follows: "The 

 nest was located in deep woods, near the base of a 

 hill which sloped down to a swampy run. It was 

 built in a small laurel {Kabiit'a latifolta), a fourth of 

 an inch in diameter at the base. About five inches 

 from the ground the bush separated into three branches, 

 and in this triple fork the nest was situated. It has a 

 firm and compact appearance. It was composed out- 

 wardly of what appears to be dry bark of grape-vine, 

 with a few twigs and roots. This is covered in m.any 

 places with a reddish woolly substance, apparently 

 the outer covering of some species of cocoon. The 

 inside is composed of small black roots and hairs. 

 The nest contained four eggs." This nest was found 

 June 8, 1874. "The second nest I discovered on the 

 13th of the same month. It was about 80 rods dis- 

 tant from the first, on level ground, and near a pi^ce
