BIRDS OF NEW YORK 423 



Blackburnian's warble is scarcely distinguishable from that of the Ceru- 

 lean's and, in fact, both of these warblers have the same habit of flying 

 through the tree tops, hurriedly warbling their songs, apparently giving no 

 heed to the incubating female. While I have observed the Blackburnian as 

 late as July i, locating themi by the song, I have found but one nest, which 

 was on June 7, 1903. It contained 4 eggs and the situation was on the 

 top of a gully bank in a hemlock rather isolated from the others over a bush 

 grown area. It was placed 25 feet up and about 10 feet from the body 

 of the tree in the end of a limb and effectively concealed from view. The 

 female sat very closely and when flushed remained within 10 feet, slowly 

 flying about uttering a mild chip of alarm. The male did not appear. 

 The nest is a neat, compact, nicely interlaced structure of hemlock twiglets 

 mixed with fine, dry grasses, the latter being inside the interlaced twigs, 

 and scantily lined with black horse hair." The eggs are grayish white to 

 bluish white in ground color, spotted and blotched and speckled with 

 cinnamon and olive brown; average size .68 by .50 inches. The nesting 

 date in New York varies from May 24 to June 12. Like most of our 

 warblers, this species evidently rears only one brood in a season.
