U. S. p. K. E. EXP. AND SURVEYS — ZOOLOGY — GENERAL REPORT. 



The specimens exhibiting the highest development of claw are from Fort Tejon, but the other 

 localities mentioned illustrate the same peculiarity very readily. Specimens frequently occur, 

 however, which it is difficult to refer positively to any one of the three species with spotted 

 scapulars ; some of them may possibly be hybrids.

This plainly colored bird is among the largest of the North American species, and is without 

 any blotches, spots, or variations of importance from one color, except on the chin and sides of 

 the head. The bill is similar to that of P. erythropldhalmus, but the cutting edge is less concave 

 and more sinuated. The tail is more graduated ; the claws thicker and stronger. The wings 

 are short and much rounded ; the first quill shorter than the secondaries.
