106 SYLVICOLIDA, WARBLERS.—GEN. 37. 
Eastern North America, West Indies, Mexico, Alaska (Dall). 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 “ovenbird.” Wiuts., ii, 88, pl. 14, f. 2; Nurr., i, 355; Aup., Orn.

** Crown plain, like the back; a conspicuous superciliary line. 
Water Thrush. Water Wagtail. (Puate ur; figs. 9,10, 11; 9a, 10a, 
lla.) Deep olivaceous-brown ; below, white, more or less tinged with pale 
yellowish, thickly and sharply spotted with the color of the back, except on 
lower belly and crissum: superciliary line yellowish; feet dark. Length 
53-6; wing 23; tail 24; bill about 4. 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. Wruts., iii, 66, pl. 22, f. 5;

Large-billed Water Thrush. (Puiare m1, figs. 8, 8a.) Very similar to the 
last; rather larger, averaging about 6, with the wing 3; bill especially 
longer and stouter, over 4, and tarsus nearly 1. Under parts white, only 
faintly tinged, and chiefly on the flanks and crissum, with buffy (not 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 very common; north to Massachusetts (Allen). Aup. Orn. Biog. i,

37. Genus OPORORNIS Baird. 
Connecticut Warbler. 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 anywhere ; 
54; wing 2}; tail 2. In spring birds the ash of the head, throat and breast 
is quite pure, and then the resemblance to G'eothlypis 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). Wits., v, 64, pl. 24, f. 4; Nurr., 2d ed. i,
