BIRDS OF THE BAHAMA ISLANDS. 55 



PARULA AMERICA XA . (L:>in.) 

 Blue Yellow-backed Warbler. 



Winter Pbuiiagc, Male. — Above, blue; a slight tinge of yellow 

 upon the crown and nape ; middle of the back with a broad patch 

 of greenish yellow ; throat and breast, yellow, with an imperfect band 

 of blue across the jugulum anterior to one of brown intermixed 

 with yellow; a small white spot on the eyelid; sides of the head, 

 ashy blue; two well-defined white bands on the wings; belly, white, 

 shading into ash upon the sides and flanks, and yellowish upon the 

 crissum ; tail, with the exception of the two middle feathers, show- 

 ing a patch of white upon the inner webs. 



Winter Plumage, Female. — Above, olive ; under parts, dull 

 white, sometimes showing a tinge of brownish on the breast. 



Length 4.40, wing 2.35, tail 2, tarsus .65. 



Not uncommon during the winter. All the specimens procured 

 were taken at Nassau, N. P., but there is no doubt that it ranges 

 throughout the islands, as it is known to have a much greater 

 southern range than the Bahamas. Dr. Bryant found it common 

 during his visit to these islands in 1S66. 



All the specimens obtained by me were killed among the small 

 trees bordering the road ; but none were seen in the " pine barrens,"
