A HYBRID SPARROW (ZONOTRICHIA ALB I- 

 COLLIS + J UNCO HTEMALIS). 



BY WITMER STONE. 



The rarity of hybrid birds in a state of nature and the great 

 interest which they possess, not only for ornithologists, but also 

 for naturalists in general, renders it desirable that such hybrid 

 specimens as have been secured should be well described and 

 figured. With this object in view the Editors of 'The Auk' have 

 had the accompanying plate prepared, illustrating the hitherto 

 unfigured hybrid between the White-throated Sparrow and Slate- 

 colored Junco. The original painting from which the plate was 

 made is the work of Mr. Ernest E. Thompson, who is well 

 known for his many beautiful illustrations of bird life. The bird 

 here represented was secured by Mr. William L. Baily near 

 Haverford College, in Montgomery County, Pennsylvania, on 

 December 12, 1SS2, and was first described in the Bulletin of the 

 Nuttall Ornithological Club, Vol. VIII, p. 7S, by Mr. Charles 

 H. Townsend.
