106 SYLVICOLIDiE, WAEBLEBS. GEN. 37. 



Eastern North America, West ludies, Mexico, Alaska {Doll). A very 

 common bird in open woodland, spending much of its time on the ground 

 rustling among the leaves ; noted for its loud monotonous song, and its 

 curious nest, which is placed on the ground and roofed over ; whence the 

 name "oveubird." Wils., ii, 88, pi. 14, f. 2 ; Nutt., i, 355 ; Aud., Orn. 



Biog. ii, 253; V, 447; pi. 143; Bd., 260 aurocapillus. 



** Crown plain, like the back ; a conspicuous superciliary line. 



-.-''"'- Water Thrush. Water Wagtail. (Plate ii ; figs. 9, 10, 11; 9ffl, 10a, 

 11a.) Deep olivaceous-brown ; below, white, more or less tinged with ^afe 

 yelloivish, thickly and sharply spotted with the color of the back, except on 

 lower belly aud crissum : superciliary line yellowish ; feet dark. Length 

 5J-6 ; wing 2| ; tail 2J ; hill about ^. North America, everywhere ; a com- 

 mon bird of low watery thickets, in the habit of constantly vibrating the 

 tail as it moves about in the underbrush. Wils., iii, 66, pi. 22, f. 5; 

 Nutt., i, 353 ; Aud., Orn. Biog. v, 284, pi. 433 ; Bd., 261. noveboracensis. 



Q^^. Large-hilled Water Thrush. (Plate ii, figs. 8, 8a.) Very similar to the 

 ' last ; rather larger, averaging about 6, with the wing 3 ; bill especially 

 longer and stouter, over J, aud tarsus nearly 1. Under parts white, only 

 faintly tinged, and chiefly on the flanks and crissum, with buflfy (uot sul- 

 phury yellow) ; the streaks sparse, pale, and not very sharp : throat, as well 

 as belly and crissum, unmarked ; legs pale. It may prove only a variety, 

 but I have yet to see a specimen I cannot distinguish on sight ; the size of 

 the bill is not by any means the only character, as some seem to suppose, 

 though it is the principal one. Eastern United States, rather southern, and 

 not yevy common; north to Massachusetts {Allen). Aud. Orn. Biog. i, 

 99, pi. 19; Bd., 262 ludovicianus. 



37. Genus OPORORNIS Baird. 



■; 'j Connecticut Warhler. Olive-green , becoming ashy on the head ; below, 

 ' from the breast, yellow, olive-shaded on the sides ; chin, throat and breast 

 brownish-ash ; a whitish ring round eye ; wings and tail unmarked, glossed 

 with olive ; under mandible and feet pale ; no decided markings anj'where ; 

 5i ; wing 2f ; tail 2. In spring birds the ash of the head, throat and breast 

 is quite pure, and then the resemblance to Geothlyjpis Philadelphia is close ; 

 but in the latter the wings are little if any longer than the tail. In the fall 

 the upper parts from bill to tail are nearly uniform olive. Eastern United 

 States, not common, and very rarely observed in the spring ; a quiet, shy 

 inhabitant of brushwood and thickets. Of late very abundant in the fall 

 about Cambridge, Mass., where in two seasons over a hundred specimens 

 have been taken {Allen). Wils., v, 64, pi. 24, f. 4; Nutt., 2d ed. i, 



403; Aud., ii, 71, pi. 99; Bd., 246 agilis. 



filj, Kentucky Warhler. Clear olive-green ; entire under parts bright yellow, 

 olive-shaded along sides ; crown black, separated by a rich yelloAV super- 

 ciliary line (which curls around the eye behind) from a broad black bar
