neck black, which color predominates on the breast; abdomen 

 white; flanks streaked with dusky. Female with the yellow spot 

 on the crown faintly developed ; the yellow markings on the rump 

 and sides of the body much paler. 



Length five inches, wing two and three quarters. 



This abundant species remains with us long after all the rest of its 

 tribe have gone to their vv^inter quarters. Late in autumn, in compa- 

 ny with the Red-breasted Thrust or Robin, it frequents the cedar- 

 trees, the berries of which at this season, form the principal portion 

 of its food. At this period the plumage of the male is similar to 

 that of the female.

 neck, and sides of the body also black, rest of the lower parts white ; 

 upper parts dull blue ; wings and tail blackish-brown — the quills 

 towards their base white, forming a conspicuous patch on the wings; 

 outer three tail feathers with a patch of white on their inner webs 

 near the ends ; primary and tail feathers margined with blue. Fe-

 lower parts dull yellow ; the white markings on the Avings and tail 

 less conspicuous. Young similar, vv^ith a dull white line from the

The Black-throated Blue Warbler takes up its residence in the 

 woods convenient to stagnant pools or shallow streams that abound 

 with winged insects, vvhich constitutes the larger portion of its food. 

 At times it is seen moving along the lower branches, or searching 

 among the moss on the trunks of trees, for various species of insects. 

 Its nest I have never found. It arrives in the latter end of April
