246 BIRDS—-SYLVICOLID & 
The nest of the Maryland Yellow-throat is usually placed on the ground, 
in weeds, in a grassy place. It is composed mainly of dead leaves and 
grass, with a lining of fine grasses. The eggs are white, rather thickly 
sprinkled with spots of reddish-brown. Tiey are from four to six, and 
vary in size from .55 to .72 in length, by .48 to .58 in breadth.

Bright olive, below clear yellow; on the head the olive passes insensibly into ash; in 
high plumage the throat and breast are black, but are generally ash, showing black 
traces, the feathers being black, skirted with ash, producing a peculiar appearance sug- 
gestive of the bird’s wearing crape; wings and tail unmarked, glossed with olive; under 
mandible aud feet flesh color; no white about eyes. Young birds have little or no ashy on 
the head, and no black on the throat, thus nearly resembling Oporornis agilis. Length, 
4-54; wing and tail, each, about 24. 
Habitat, Eastern Province of the United States and British America; north casually 
to Greenland ; west to Kansas and Dakota. New Granada. Costa Rica. 
Rather rare spring and fall migrant. Arrives after the middle of May, 
and again in August and September. It has been taken in Northern 
Ohio by Mr. Winslow, Dr. Kirtland, and Dr. Darby. Mr. Langdon’ notes 
two or three specimens near Cincinnati. I have taken six specimens in 
this vicinity. When with us it is a shy, retiring, and silent bird, fre- 
quenting thickets and brush-heaps in woodland undergrowth. It has 
much less curiosity than the preceding species. All which I have seen. 
were busily engaged searching for food on the ground, and when dis- 
turbed, flew but a short distance to a dense thicket for concealment. I 
saw one specimen in my garden on the ground beneath currant bushes. 
They very likely breed in this State. The only nest known was found 
by Mr. John Burroughs, in the State of New York, in ferns, about a foot 
from the ground, on the edge of a hemlock wood. It was quite massive, 
composed of stalks and leaves. The cavity was quite deep, and lined 
with fine black rootlets. The eges were three in number, measuring .79 
by .55. They ‘were of a light flesh color, uniformly speckled with fine 
brown specks.” Young birds have the entire under parts yellow. 
Sub-family ICTHRIIN At. Chats. 
Bi conical, high and compressed, culmen and commissure much curved, without notch 
er bristles; wing much rounded, shorter than the tail.
