Spr. Ca.—Bill as long as the head. Above brown ; darkest on the head, which is unspotted. Feathers on the back streaked 
centrally with white. Beneath whitish, tinged with rusty on the belly ; the feathers of the throat and upper parts, and under tail 
coverts, with large rounded black spots ; those of the remaining under parts with smaller, more linear ones. Chin and line over 
the eye white. Tail feathers black beneath, barred subterminally (the outer one throughout) with white. 
Length, 8 inches ; wing, 3.40 ; tail, 3.55 inches. 
Hab.—V alleys of Rio Grande and Gila. Southward. = 
(7149.) This, the largest wren found in the United States, bears a slight resemblance to 
the common creeper, Certhia americana, but differs greatly in all essential features. The bill, 
from the base of the skull, is about the length of the latter, and is considerably compressed and 
slightly decurved. The tail is long and broad, about equal to the wings. The black spotting 
on the throat is very conspicuous, relieved only slightly by the white edges of the feathers. 
There is a black maxillary stripe. Each feather on the back, including the wing coverts, may 
be said to have two whitish spots strung along the white midrib, the light portion bordered by 
a duskier shade than the extreme margin of the feather. 
The outer edges of the quills are indented by triangular spots of whitish ; the basal portion 
of the inner webs somewhat similarly marked. The two middle tail feathers are brown, some- 
what like the crown, but with indistinct bands of darker ; the others are as described. 
Specimens vary considerably in the length of the bill, and in the amount of black spotting on 
the throat. In a female, 7150, the white streaks on the back are somewhat wider. The second 
tail feather is sometimes banded almost as much as the first, and the inner tail feathers are 
distinctly and narrowly banded with whitish and black, instead of dark brown, and lighter.
