lay bleeding under one wing, with most of its tail feathers torn out 

 while I retrieved the hawk, and then, as I returned, recovered suf- 

 ficiently to fly away. The falcon is an adult female of the eastern 

 subspecies, marked by its darker color. 



I recorded a pigeon hawk on the Rio Escota, near Santa Maria, 

 Herrera, on March 8, 1948, and one at Panama Viejo, Panama, 

 February 2, 1952. The records are listed here, though the subspecies 

 is uncertain.

The three records for this western subspecies are as follows : A 

 female came at sunset on April 15, 1946, to rest in the top of a 

 tall tree standing beside our quarters near the air strip at Jaque, 

 Darien, We had been occupied through the day in packing in readi- 

 ness for a plane to call for us early the following morning so that 

 guns and ammunition were not available. As Perrygo and I watched 

 the bird with longing eyes, and the wish that we had it, Tom Watson, 

 Air Force sergeant, an expert marksman, brought it down with his 

 service rifle from a distance of 90 meters, I expected to retrieve 

 broken bits of skin and feathers, but instead I found that with careful 

 aim he had creased the falcon across the back of the neck and the 

 head so that it was only slightly marked. Two additional specimens 

 in the Brandt Collection at the University of Cincinnati were taken 

 by H. von Wedel — a female at Bocas del Toro, September 29, 1938, 

 and another (from its size, probably a male) secured at Puerto 

 Obaldia, San Bias, October 16, 1934. 



This western form, the breeding race from Alaska across to 

 northern Saskatchewan, and south to Oregon and Idaho, has been 

 reported previously in migration only to southern Mexico. It is 

 slightly paler in color in adult and immature than the eastern race, 

 with the paler markings in the female and immature more buflF. The 

 specimen from Jaque is a female of the previous season. It is probable 

 that the race equals the typical one in its southward limits, as there is
