BIRDS OF FENNSYLVANIA. 
red ; top of head red but not as bright as iu male. The red on top of head of young 
male is often of a coppery hue. Length about 5| inches ; extent about 9 inches. 
Habitat . — Northern portions of Northern Hemisphere, south irregularly in winter, 
in North America, to the middle United States (Washington, D. C., Kansas, south- 
eastern Oregon). 
The Redpoll, a native of liig-h northern latitudes, occurs in the south- 
ern parts of Pennsylvania only as an irregular and occasional winter 
visitant, but in some sections of the northern portions of the state it 
appears to be a rather common and regular winter visitor. Redpolls 
were exceedingly abundant in eastern Pennsylvania in the winter of 
1878-79, at which time they were observed about fields and houses in 
flocks of from twenty to two hundred or more. Last Avinter (1889-90) 
they were found in large flocks in the neighborhood of Montoursville, 
Lycoming county, by Mr. F. F. Castlebury, and they were also quite 
plentiful in different sections of Wyoming, Lackawanna and Susque- 
hanna counties, where a number of sjDecimens were obtained by Mr. 
George P. Friant, of Scranton, and myself. The note of the Redpoll is 
very similar to that of the American Goldfinch {Spinus tristis, Linn.). 
The food, during their sojourn with us, consists almost entirely of seeds 
of various grasses and weeds ; the buds of different trees and some few 
insects are also eaten. 
Genus SPINUS Koch. 
Spinus tristis (Linn.). 
American Goldfinch; Salad-bird; Wild-canary; Yellow-bird; Thistle- 
bird. 
Description {Plate Si. Fig. I, adult male in summer^. 
Legs, feet and bill flesh color. The male in early autumn loses his black cap, and 
his bright yellow^ upper and lower parts change to a dull brownish or greenish-yel- 
low, similar to the general plumage of the female. The male in winter may often 
be distinguished by the darker tail and wing feathers with their more conspicuous 
white or whitish markings. 
Female . — No blackcap; upper parts olivaceous; wings and tail dusky, marked 
with whitish as in male ; lower parts whitish, more or less tinged with j^ellowish. 
Young . — Like winter adults, but duller in color. Length about inches ; extent 
about 9 inches. 
Habitat . — North America generally, breeding southward to the middle districts of 
the United States (to about the Potomac and Ohio rivers, Kansas and California), 
and wintering mostly south of the northern boundary of the United States. 
The American Goldfinch is a common resident in Pennsylvania dur- 
ing all seasons. These birds are usually observed in flocks which move 
from one locality to another as their food diminishes. Even in the 
breeding season (June, July and August), it is not uncommon to find 
several families nesting within a short distance of each other. The 
males in summer frequently associate in small flocks. The nest, an ex- 
ceedingly neat and beautiful cup-shaped structure, is composed exter-
