38. Genus GEOTHLYPIS Cabanis. 



Maryland Yellow-Uiroat. $ in spring : olive- 

 green, rather grayer anteriorly, forehead and a 

 broad band through the eye to the neck pure black, bordered above with 

 hoary ash; chin, throat, breast, under tail coverts and edge of wing rich 

 yellow, fading into whitish on the belly; wings and tail unmarked, glossed 

 with olive ; bill black, feet flesh colored. $ in spring, without the definite 

 black and ash on the head, the crown generally brownish, the yellow pale 

 and restricted. The young, in general, resembles 

 the ? , at any rate lacking the head markings of the 

 $ ; but it is sometimes huffy brownish below, some- 

 times almost entirely clear yellow. In any plumage, 

 the bird is distinguished from warblers of any other 

 genus, by having the wings shorter, or at most not 

 longer, than the tail ; aud from the two following 

 species by having no clear ash on the throat. Length 

 4|-5 ; wing and tail 1^-2J. United States, from 

 Atlantic to Pacific ; Mexico, West Indies and Central America. An abund- 

 ant and familiar inhabitant of shrubbery <ind underbrush, the sameness of 

 which is enlivened by its sprightly presence and hearty song, throughout 

 the summer months. WiLS., i, 88, pi. 6, f. 1; Nutt., i, 401; Aud., ii,

Mourning Warbler. 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 suggestive of the bird's 

 wearing crape ; wings and tail unmarked, glossed with olive ; under mandi- 

 ble and feet flesh color ; no white about eyes. Young birds have little or 

 no ashy on the head, aud no black on the throat, thus closely resembling 

 Oporornis agilis, but are of course distinguishable by their generic charac- 

 ters ; 5^-5 J ; wing and tail, each, about 2J. Eastern United States, rare; 

 Minnesota, "abundant" (^Trippe) ; a shy, retiring inhabitant of dense shrub- 

 bery. WiLS., i, 101, pi. 14; Nutt., i, 404; Aud., ii, 76, pi. 101; Bd.,
