BIRDS OF NEW YORK 273 



is on the wing, which may be described as intermediate between the cor- 

 responding rolling call of the White- winged crossbill and the ordinary piping 

 call of the Red crossbill, though somewhat softer than either " (Gerald 

 Thayer). On the 27th of March 191 2, I heard the song of a full plumaged 

 Redpoll delivered from the peak of a tamarack in a swamp near Geneva, 

 N. Y. It resembled somewhat the ecstatic flight song of the Goldfinch, 

 but seemed to me more melodious and finer toned, more of the quality 

 of the " tweet " call of the Goldfinch and less of the warbling quality, but 

 delivered in the manner of the Goldfinch's warble. The Redpoll is fully 

 as gregarious as the Crossbill, is rarely found except in flocks of from 20 

 to 50, sometimes 200 or 300. When the flocks take wing they keep up 

 a combination of twittering and chirping very characteristic of the species. 

 In habits they are wholly beneficial, feeding only on seeds of trees or on 

 the seeds of harmful weeds which grow in the field.

Distribution. This subspecies of Redpoll breeds in the holarctic 

 region, in America on the islands of the Arctic coast, especially Herschel 

 island, and wanders southward in winter as far as Quebec, Ontario, Maine
