may be Ludovicianus. The shooting of the latter and finding its 
nest and eggs at Norwich, Ct., by Mr. E. Ingersoll, make the 
theory tenable. - 
One instance of the nesting of Mimus polyglottus has come to 
his knowledge. Cuthartes aura and Garzetta candidissima he has 
seen rarely and has heard of Cardinalis Virginianus. All through 
the winter of 1872-73, Sialia sialis, Dendreca coronata and Melo- 
thrus pecoris remained in flocks. The worm-eating warbler he 
finds in thickets on the edges of swamps, —a restless’ bird with a 
very strange, loud, rattling call ; at other times he remarked a war- 
bling song reminding him of that of the common goldfinch, only 
a little softer. Sphyrapicus varius is abundant in fall. He con- 
siders Ammodromus maritimus as being much more plentiful than 
caudacutus. His observations of Oporornis agilis are the same 
as those of Massachusetts collectors. It occurs only in the fall 
(September). My correspondent has kindly sent me specimens in 
the flesh, and nests and eggs of many of the above species in con- 
firmation of what he has written me. No part of New England 
has been embraced within the Carolinian fauna, and properly so, 
but that its southern border has a tinge of it, is quite evident. 
In this connection I will state that several Melanerpes erythro- 
cephalus have been shot in eastern Massachusetts within about a 
year in both the adult and immature plumage. Two Picoides arc- 
ticus, both males, were shot in Middlesex county, late in the fall of 
1871. A nest and eggs of Icteria virens were found near Lynn 
last June, the fourth nest of this bird that my informer has found 
in that locality. A fine specimen of Herodias egretta was killed in 
Westford ; Limosa Hudsonica has been quite common along the 
coast this fall; a Porzana Noveboracensis was shot on Canton 
marshes, Oct. 15, 1872; a Histrionicus torquatus at Hampton, 
N. H., Novy, 1872; and two or three young Sterna Forsterii have 
been obtained on our coast within a year.—H. A. Purn, West 
Newton, Mass., Sept., 1873. 
On THE MIGRATION OF CERTAIN ANIMALS AS INFLUENCED BY 
Civitization.—During the autumn of 1850, I emigrated to the 
state of Wisconsin and settled upon what was known as the “In- 
dian Lands,” situated in the central part of the state, north of 
Fox River. The Indians were not removed, and very few white 
Settlements had been made. The forests abounded in the usual
