298 
Lores and region about the eye dusky, without any trace of a pale ring. Upper 
parts and sides of body clear olive-green; the under parts bright yellow. Tail- 
feathers uniform olive; first primary with the outer half of the outer web nearly 
white. 
“ Female with the gray of the crown glossed with olive ; the chin and throat paler 
centrally, and tinged with fulvous ; a dull whitish ring round the eye. Length 5.50; 
wing 2.45 ; tail 2.25.”— From Orn. of III.

ainous portions of Pennsylvania, New England and New York, and northern 
Michigan, northward. Central America and northern South America in winter. 
The Mourning Warbler breeds regularly in a few secluded mountain¬ 
ous districts of Pennsylvania. Duiing 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. Yan 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. 
Goethlypis trichas (Linn.). 
Maryland Yellovv-throat. 
Description (Plate 42 ). 
Length of male about 5£ ; extent about 7| ; female rather smaller ; bill back ; legs 
pale-brown. 
Male, in summer .—Above olive-green ; forehead and a broad band through the 
ej^es and on side of neck pure black, bordered posteriorly with ashy ; chin, throat, 
breast, under-coverts, and edge of wing bright yellow, fading into a dull butf-white 
on belly ; wings and tail, glossed with yellowish-olive. 
Female, in summer.— Colors duller ; less yellow on under parts ; no black or ashy 
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. 
Habitat .—Eastern United States, mainly east of the Alleghanies, north to Ontario 
and Nova Scotia, breeding from Georgia, northward. In winter, south Atlantic and 
Gulf States and the West Indies. 
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, yet 
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.
