518 NORTH AMERICAN BIRDS. 
Genus SEIURUS Swainson. (Page 482, pl. CXVILI, fig. 3.) 
Species. 
Common CHaractrrs.—Above plain dusky, brownish, or olive, the top of the 
head, in one species, striped with blackish and orange-rufous; lower parts white, 
streaked with brown or dusky. Nest on ground or in hollow stumps or logs near 
ground, well hidden, very bulky, loosely put together, the exterior composed of 
dead leaves, etc., the lining of fine rootlets, grasses, ete. Hggs 3-6, pure white or 
creamy white, spotted with reddish brown and lilac-gray. 
a. Top of head with two lateral stripes of blackish, enclosing a median one of orange- 
rufous; no white superciliary stripe, but with a distinct whitish orbital ring. 
Adult: Above greenish olive, beneath pure white, the breast and sides 
streaked with dusky or black. Youny: Above fulvous brown, the 
wing-coverts tipped with lighter fulvous, or buffy; lower parts pale 
fulvous, or buffy, very narrowly streaked on breast, etc., with dusky ; 
stripes on top of head very indistinct, or obsolete. Length about 5.40- 
6.50, wing 2.75-3.00, tail 2.00-2.25. West in dry woods, embedded in 
ground, well concealed, the top usually roofed over or covered, the en- 
trance more or less to one side. Hggs .80 x .61. Hab. Eastern North 
America, north to Hudson’s Bay and Alaska, breeding from 38°, or 
lower, northward; west to eastern base of Rocky Mountains; south, in 
winter, to southern Florida, West Indies (including Bahamas), Mexico 
(both sides), and Central America, nearly to Panama. 
674. S. aurocapillus (Linn.). Oven-bird. 
a, Top of head plain brown, or dusky, like back (sometimes with indication of a 
paler median streak anteriorly); a distinct whitish or pale fulvous super- 
ciliary stripe; with a dusky or brownish stripe beneath it, through eye; 
no whitish orbital ring. 
6. Superciliary stripe more or less fulvous; streaks on lower parts darker than 
upper surface ; throat always (?) distinctly speckled ; longer under tail- 
coverts with nearly whole of concealed portion (both webs) brownish or 
dusky ; lower parts never tinged with buffy laterally or posteriorly, but 
often uniformly tinged with sulphur-yellow; wing exceeding tail by a 
little less than length of tarsus. Young: Similar to adult, but feathers 
Jamaica, and has received in one collection from the Bahamas more than fifty specimens, representing most of 
the islands in the group; yet every one in this large series, and also among those from Key West, is absolutely 
typical. D. hypochrysea has not yet been traced farther south than Hibernia, northern Florida, its winter 
range being apparently restricted to the southern Atlantic and Gulf States. It would thus appear that the 
reapective migrations of the two forms intersect, though it may be that both occur together, to some extent, 
during winter. The only examples of D. hypochrysea I have seen from any locality west of the Atlantic coast 
(an adult and a young of the year from “ Mississippi River, Louisiana,” February 5 and 21, 1870, in Mr. Hen- 
shaw’s collection) are in every respect typical of that form.
