The Mourning- Warbler breeds regularly in a few secluded mountain- 

 ous districts of Pennsylvania. During- migrations is found very gener- 

 ally throughout the state, but in all localities is reported to be rare. 

 Mr. Otto Behr informs me that the Mourning- Warbler breeds regularly 

 in the mountainous regions of Sullivan county, and Dr. Van Fleet has 

 observed as a native about Renovo, in Clinton county. Frequents 

 thickets and undergrowth ; two specimens obtained by the writer were 

 both shot in brush piles along the edge of a swampy thicket. This 

 warbler arrives here usually from the 15th to the 20th of May. Food 

 of two birds examined by the writer consisted of beetles and spiders.

 eyes and on side of neck pure black, bordered posteriorly with ashy ; chin, throat, 

 breast, under-cbverts, and edge of wing bright yellow, fading into a dull buff-white

 head markings ; top of head, especially forehead, reddish-brown. The young gen- 

 erally resemble the female, but young males may usually be known by indistinct 

 black feathers on sides of head, though feathers of forehead are quite similar to 

 those of female.

The Maryland Yellow-throat is an exceedingly abundant summer res- 

 ident from about May 1st to the latter part of September. During 

 migrations, particularly in the spring, it often visits apple trees to seek, 

 among the leaves and blossoms, for numerous small insects. Frequents, 

 especially, thickets, tangled underbrush, brush-piles and high weeds, 

 generally near streams or swampy places. Its voice is rather loud, yefc 

 its song is not unmusical. 



This species builds a rather large cup-shaped nest of leaves and dried 

 grasses, usually carefully concealed in a tussock of grass, among weeds, 

 or at the base of low bushes, commonly in low and moist situations.
