HELMINTHOPHAGA CHRYSOPTERA, Baird.—Golden winyed Warbler.— 
Of this species, which has hitherto been considered rather rare in this 
vicinity, six specimens were taken between May 2d and 5th, 1881, at 
Brookville, Indiana, by Messrs. KE. R. Quick and A. W. Butler. 
HELMINTHOPHAGA PEREGRINA, Baird.—Zennessee Warbler.—The 
fact that fall specimens of this species, in this locality at least, are al- 
most invariably characterized by an abrupt whitish tipping of the 
primaries, seems to have been entirely overlooked by writers; at least 
we have been unable to find any reference to this feature, Its presence 
also suggests the query, are the primaries moulted twice a year, or is 
the whitish tipping simply due to an incomplete or transition stage 
of pigmentation, which is fully developed by the tollowing spring, 
when the feathers are brownish to their tips? The latter view certainly 
seems the more probable of the two. 
GEOTHLYPIS PHILADELPHIA, Baird.—Mourning Warbler.—Specimen 
taken May 7, 1881, at Brookville, Indiana, by A. W. Butler. 
STELGIDOPTERYX SERRIPENNIS, Baird.—Rough-winged Swallow. 
CERYLE ALCYON, Boie._—King fisher. 
On May 22, 1879, we took from their burrows, in the bank of a dry | 
creek, the nests of a Rough-winged Swallow, and of a Kingfisher, each 
of which was presided over by one of its owners. Each burrow was, 
in addition, inhabited by a colony of Humble Bees, members of which 
were passing in and out continuously, seemingly in perfect harmony 
with the feathered occupants of the burrows ; and it is wogthy of note 
that the Hymenopterous denizens “held the fort” with better credit to 
themselves, and more impression on the attacking party, than did 
either of the birds. In justice to the Kingfisher, however, it should be 
noted, that the male, who was incubating the eggs at the time, re- 
fused to leave even when urged to do so with a stick; and, finally, had 
to be seized by the bill and lifted off the eggs. 
On May 22, 1879, Mr. Charles Tompkins, of Madisonville, Ohio, 
took from a crevice in the wing-walls of a culvert, a nest of S. serri- 
pennis, containing seven eggs, the largest number we have yet observed 
in a set. Ofa dozen or more nests of this species, taken on the same 
dates (May 20-21), those from inland situations (along creeks and 
bridges) were complete in number (5 to 79and well advanced in incu- 
bation ; while those from river banks were, with one or two exceptions, 
incomplete, containing only from one to four eggs, which in all cases 
were fresh.
