MARYLAND YELLOAY-THROAT. 
Geothlypis trichas. 
Char. Above, olive, duller on the head, brighter on rump ; fore- 
head and broad band on side of head black, with whitish border ; beneath 
rich yellow, paler on the belly. Length to 5?^ inches. 
Nest. Hidden by tuft of grass, or amid tliicket of briers, usually in a 
moist woodland or on border of swamp ; composed exteriorly of loosely 
laid grass, twigs, etc., lined with fine grass compactly woven. 
Eggs. 4-6 ; white, sometimes creamy, spotted around larger end with 
brown and lilac ; often a few black spots and lines ; 0.70 X 0.52. 
This common and familiar species extends its summer mi- 
grations from Florida to Nova Scotia, arriving in Pennsylvania 
towards the middle of April, and in this part of New England 
about the first week in May. The majority return to the South 
in September ; a few stragglers of tlie young, however, may be 
seen to the first week in October, and though some may re- 
main and winter in the Southern States, it is more probable 
that the main body retire at this season into the interior of 
tropical America, as they were seen late in autumn around 
Vera Cruz by the naturalist and traveller Mr. Bullock. Early 
in the month of March, however, I heard this species singing 
in the forests of West Florida. 
The Maryland Yellow-Throat, with cheerful devotedness to the 
great object of his summer migration, — the attachments and 
cares of his species, — passes his time near some shady rill of 
water, amidst briers, brambles, alders, and such other shrubbery 
as grows in low and watery situations. Unambitious to be seen,
