45 2 Roosevelt Wild Life Bulletin 



tree trunk or a stout branch in a creeper-like manner, searching the 

 crevices of the bark for insects and their larvae or eggs. Its voice 

 is thin and sharp. The nest is situated on the ground. 



Blue-headed Vireo. Lanivireo solitaries solitaries (Wils.) 



Length 5.6. Head slaty; back lighter gray; wing-bars white and a 

 white space about the eye ; under parts white, brownish at the sides. 



The Blue-headed Vireo inhabits woodlands. Its preference 

 is for timber in the dry, open aspect, where the upper portions of 

 ridges support an uncrowded growth of mature hardwoods with 

 little underbrush; yet it frequently dwells in the sunlit margin of a 

 bog forest, or of a burn. 



* Warbling Vireo. Vireosylva gilva gilva (Vieill.) 



Not seen by me. Eaton says that it undoubtedly breeds in 

 every county of the State with the exception of the interior of the 

 Catskill and Adirondack districts. The Warbling Vireo may be dis- 

 tinguished from the familiar Red-eyed, by its smaller size, yellowish 

 ventral tinge, and lack of a dark line through the eye. 



Red-eyed Vireo. Vireosylva olivacea (Linn.) 



Length 6.2. Brownish above ; crown gray, with a narrow black border ; 

 whitish line over eye; lower surface white. 



The Red-eyed Vireo abounds in almost all aspects of the forest 

 except dense bog woods. It lives in clearings where small trees have 

 obtained a standing, in the borders of the Burn, and in open wood- 

 lands of every kind. It is one of the birds whose preferences for 

 timber lead them into the virgin forest, but there they require a 

 " margin " of some sort, usually a brook or a bog, which breaks the 

 forest canopy in some degree. Though it nests most commonly in 

 sapling growth it hunts and sings in the trees, preferably such as 

 form spreading tops at medium height, but it has little to do with 

 evergreens. At Barber Point a pair of Red-eyed Vireos nested 

 about six feet from the ground in a drooping fork of a maple, amid 

 blackberry and raspberry bushes ; another pair had a similar nest in 

 a small beech in the edge of the open woods ; and a third was in a 

 small maple in a bushy clearing, near the lakeshore. The nests of 

 all the vireos are much alike,— cups of bark and spider-silk hung 

 beneath a horizontal fork. The Red-eyed Vireo is a jealous watcher 

 over the space about its nest, and it manifests an especial dislike for 

 the presence of a Grackle in the trees near its home, scolding and 

 trving to drive it away. 



* Migrant Shrike. Lanius ludovicianus migrans W. Palmer 



No Shrike was seen at Cranberry Lake; but this species may be 

 noted there in future, for Eaton finds that it is a fairly common 

 breeder in western and central New York, in the Black River Val- 

 ley, Mohawk Valley, and around the outskirts of the Adirondacks.
