Nesting of the Blackburnian Warbler {Dendroica

BY DAVID E. HAEEOWER. 



In the Pocono Mountains of Pennsylvania is a paradise for 

 the bird lover, and of all the birds found there no family is so 

 well represented as the Warblers. About La Anna, in western 

 Pike County, where these observations were made, sixteen spe- 

 cies were found as summer residents. Along the roads could 

 be seen Yellow-throats, Redstarts, Yellow Warblers, Ovenbirds

 slope to my left it was not so thick, and here occurred several 

 deciduous shrubs, with moosewood, bass wood and a few small 

 hemlocks. Few flowers grew beneath this perpetual shade, and

 banks fringed with rhododendron. Before me was spread out 

 a panorama of deforested hills covered by a dense second-growth, 

 while here and there stood a lonely tree, spared for some reason 

 by the lumberman's axe. Along the border of the forest were
