PLATE LII. -BLACK-THROATED GREEN WARBLER. 



Dendroica viretis. 



Back and crown light yellowish-green ; forehead, a band over the 

 eye, cheeks and sides of the neck rich yellow ; chin, throat and breast 

 black ; wings brown, with two white bars, many of the feathers pale- 

 edged ; tail brown ; the outer three feathers almost wholly white ; bill 

 and feet dark. Length, 5.10 inches. 



Migratory. Arrives May 10, leaves October 25, This Warbler, like others of 

 its family, is most frequently observed during its migrations, when for short periods 

 it is rather abundant. It breeds here, however, and can be seen through the whole 

 Summer. 



It seems to prefer pine or hemlock trees, and usually chooses them to nest in. 



Dr. Mearns says: " It is seen in large companies, clinging to the tips of the branches, 

 exhibiting a fluttering of wings and incessant activity. Its attitudes and notes remind one 

 of the Titmice ; but it possesses a very pleasant song besides."
