528. REDPOLL. _Acanthis linaria linaria._

Range.--Breeds within the Arctic Circle; winters south to New York,
Kansas and northern California and casually farther.

This species is similar to the last but much darker, and the rump is
also streaked with blackish. These handsome birds are often met with in
winter, feeding on seeds of the weed stems that project above the snow.
Their flight and song is similar to that of the Goldfinch or Pine
Siskin. They nest at low elevations, either in trees or bushes. The eggs
number from three to six and are pale bluish, sparingly specked with
reddish brown. Size .65 x .50. Data.--Mouth of Great Whale River, Hudson
Bay, May 16, 1899. Nest in a willow 4 feet from the ground; made of fine
rootlets and grass, lined with feathers. Collector, A. P. Lowe.

528a. HOLBOLL'S REDPOLL. _Acanthis linaria holboelli._

Range.--Arctic regions; south casually to the border of the United
States.

A slightly larger variety of the common Redpoll. Eggs probably not
distinguished.

528b. GREATER REDPOLL. _Acanthis linaria rostrata._

Range.--Breeds in southern Greenland; in winter south through Labrador
to the northern border of the United States.

This variety is larger and darker than the common Redpoll. It has been
found breeding abundantly in southern Greenland, where its nesting
habits are the same as those of the Redpoll and the eggs similar but
averaging a trifle larger.

529. GOLDFINCH. _Astragalinus tristis tristis_.

Range.--North America east of the Rockies, and from Labrador and
Manitoba southward.

These beautiful birds are among our sweetest songsters from May until
September. They are resident throughout their United States range,
