Birds of Buzzard's Roost 



ers, capture a large part of their food on the wing. As a rule, 

 they are arboreal, but many are thicket haunting, and some are 

 terrestrial." 



The yellow warbler is known as the wild canary, summer 

 yellowbird, golden warbler, summer warbler, and yellow poll. 

 As its name indicates its general color is yellow. The bill of 

 the adult male is of a light blue or horn color, long, as com- 

 pared with the size of the bird and terminates in a very sharp 

 point ; iris of eye of an orange yellow ; top and sides of head, 

 clear yellow ; back, a clear yellowish olive-green ; wings and tail 

 dusky yellow ; middle and greater wing coverts broadly tipped 

 with yellow; primaries and tail feathers, dusky, edged with 

 yellow ; tail slightly forked ; entire lower parts yellow with 

 reddish stripes ; legs and feet light brown. Adult female paler 

 yellow, usually without streaks, but sometimes with a few in- 

 distinct ones on the chest. 



The range of the yellow warbler extends from Guiana 

 and Ecuador north to the Bering Sea and the Arctic coast. Of 

 its breeding range Mr. Cooke says : "If a map of the United 

 States and Canada south of the Barren Grounds was colored 

 to represent the breeding area of the yellow warbler, the uncol- 

 ored portions would comprise Florida, southern Georgia, and 

 numerous small 'islands' representing the upper parts of the 

 eastern mountains and such parts of the western mountains as 

 are above 6,000 to 8,000 feet. The summer range of the bird, 

 including the range of the subspecies sonorana in the south- 

 western part of the United States and that of rubiginosa in 

 Alaska, covers approximately 40 degrees of latitude, that is 

 to say 30 degrees to 70 degrees and 110 of longitude, that is 

 to say, 55 degrees to 165 degrees. The winter range covers 31 

 degrees of latitude, that is to say 24 degrees north to 7 degrees 

 south and 54 degrees of longitude, that is to say, 52 degrees to 

 106 degrees. The two in combination thus give an extension 

 of 77 degrees of latitude and 113 degrees of longitude." He 

 adds: "The extreme points of the yellow warbler's range 

 northern Alaska and western Peru are farther separated than 

 the extremes of the range of the black-poll warbler, which is 

 considered the greatest migrant of the family. Owing, how- 

 ever to the southerly extension of the breeding range of the
