It is less frequently seen in town than the next species in winter, 

 but singing males regularly visit the college campus during the 

 courting season. This is one of the species always comprising the 

 winter troop of small birds in woodlands. It readily responds to 

 its imitated calls, but is more wary than the Chicl<adee. It s^eldom 

 visits the lunch counter in winter. 



244. Penthestes atricapillu><. — Chickadee. 



Common over the whole wooded and iidiabited parts of the re- 

 gion all the year. It is less common on the sand spit during the 

 coldest part of the winter. It nests in orchards where suitable 

 nesting sites are left. Its confiding habits make it the favorite 

 among our resident birds. The lunch counter is patronized with 

 thanks and the birds proceed to pay their way by visiting the or- 

 chard and destroying the eggs of the apple pests. 



T have never been able to detect any migration of these two tit- 

 mice in this region at any time of year. They are decidedly local 

 in their preferences, and can be located even when nesting. On 

 numerous occasions I have started them from their night roost in 

 the thiclc of a leafy grape vine in midwinter 



245. Rcuulua satraiia. — Golden-crowned Kinglet. 



Common during the spring migration, less often conunon in the 

 fall ; wintering in small numbers in cemeteries and other places 

 where there are evergreen trees. In the migrations it occus over 

 the whole region where there are trees and bushes. It was com- 

 mon Septemlier 24 to October 23, and a few to November 5, ir)(!<> ; 

 conunon March 25 to April 29, 1907, on the sand spit, but I have 

 not found it there in winter. The spring migration occurs the first 

 week in April, and the bulk has departed before the first of May. 

 ;\Iy latest spring date is May 10, 1907. The fall migration occurs 

 about the first of October, the earliest being September 24, 1906. 

 The bull? has gone south by the first of November. 



24(j. Rcyulus ccilctidula. — Kub.v-crowned Kinglet. 



Common in the spring migrations, less common in the fall. It 

 is found with the last species, but tarries longer in the spring. I 

 liave never found it in winter. The median date of spring arrival 

 is April 13, the earliest being March 25, 1905. The bulk leaves 

 about the first of May, but individuals tarry until May 18 (1907 

 and 1908). The fall migrations occupy the whole of October. Ex- 

 treme dates are September 24. 190G, and November 3, 1901. Some- 

 times these little birds literally swarm over the bushes in the yard 

 and among the ap])le trees. Rival males display the hiden flame
