Life histories of North American wood warblers, Part 1 (of 2)

The second nest, which was within one hundred yards of the first one,
was built in a bunch of canes (_Arundinaria tecta_), and supported by a
palmetto leaf. This nest was three feet above the ground, in a
comparatively dry situation, and contained four pure white eggs in an
advanced stage of incubation. * * *
The two nests are similar, being constructed of fine grass, cane leaves,
and other leaves, the latter skeletonized. The second nest, taken April
17, is 6-1/2 inches high, 6 inches wide, 2 inches wide at rim, and 2
inches deep. It is composed almost entirely of dead cane leaves, a
little Spanish moss (_Tillandsia usneoides_), and a few skeletonized
leaves. * * *
The female is a very close sitter; indeed so close that I found it
necessary to touch her before she would leave the nest. This habit was
the same in both females.
The other nests were in low bushes, vines, or canes.
During that same year Embody (1907) discovered Bachman's warbler
breeding in Logan County, Ky., and later Holt (1920) found it nesting in
Autauga County, Ala. The localities in which these birds were breeding
and the locations of the nests were not very different from those
described above by Wayne.
_Eggs._--The egg of Bachman's warbler is ovate and pure white, and
usually glossy. The only spotted egg on record is one of a set described
by Holt (1920) as follows: "The nest contained four eggs, three of them
pure, glossy white, the other with a dozen minute dots of light brown,
mostly about the large end; all were tinted faint salmon pink by the
yolks." Three to five eggs constitute a set; three seem the usual
number, with four a close second, while five are unusual.
[AUTHOR'S NOTE: The measurements of 42 eggs average 15.8 by 12.4
millimeters; the eggs showing the four extremes measure =16.6= by 12.9,
16.5 by =13.0=, =14.9= by 12.2, and 15.8 by =11.6= millimeters.]
_Plumages._--[AUTHOR'S NOTE: Two young birds, just able to fly from the
nest and taken by Wayne on May 13, are thus described by Brewster
(1905):
