FAMILY TYRANNIDAE 457 



the Rio Changuena in the mountains of northwestern Bocas del Toro, 

 by R. Hinds working under the direction of Dr. Pedro GaHndo, are 

 identified as this race. A male, collected by Galindo, March 13, 1971, 

 near the summit of Cerro Quia, Darien, is in full molt, indicating 

 that it was a wintering individual. 



CONTOPUS SORDIDULUS VELIEI Coues 



Contopus veliei Coues, Proc. Acad. Nat. Sci. Philadelphia, vol. 18, March 1866, 

 p. 61. (Mountains of Colorado Territory.) 



Characters. — Lighter gray above and below than safiirafus. 



Measurements. — Males (10 breeding season birds from Cali- 

 fornia), wing 82.^89.4 (87.0), tail 61.0-65.7 (63.1), culmen from 

 base 15.3-16.9 (16.1), tarsus 13.2-13.8 (13.4), tip of longest upper 

 tail covert to end of tail 30.0-32.5 (31.6) mm. 



Females (10 breeding season birds from California, Nevada, and 

 Arizona), wing 80.5-86.5 (83.1). tail 57.2-64.9 (60.8), culmen from 

 base 14.5-16.5 (15.5), tarsus 13.2-13.8 (13.4). tip of longest upper 

 tail covert to end of tail 28.0-32.6 (30.4) mm. 



Passage migrant from the north to winter quarters in northern 

 South America ; fairly common. 



While it is assumed that most of the sight records identified by 

 call notes may be this race, few actual specimens have been collected. 

 Fall records in Panama include the following : One taken in the 

 Canal Zone on October 9, 1953, and one at Ouiel, altitude 1640 meters 

 above Boquete, Chiriqui, December 7, 1931. The last is the latest 

 date for fall in Panama. In northward movement, one was taken 

 March 7, 1956, at 1370 meters on Cerro Pando, beyond El Volcan, 

 Chiriqui ; one March 2, 1971 at 790 meters on Cerro Quia, and an- 

 other April 7, 1946 at Jaque, in eastern Darien. 



The specimens described by Burleigh as Contopus sordidulus 

 amplus, as stated above, are considered intermediate between veliei 

 and saturatus, but near veliei. It should be noted in connection with 

 this allocation that of two listed (loc. cit., p. 145) as from the Panama 

 Canal Zone only the male of "9 October 1953" is C. s. veliei. The 

 female of "30 September 1953" is Contopus virens. 



In the original description Coues wrote "we have been in the habit 

 of designating these gray specimens as Contopus Veliei after Dr. 

 Velie, who sent the first example from the mountains of Colorado 

 Territory." This was Dr. Jacob W. Velie. physician, ornithologist, 

 early secretary and curator of the Chicago Academy of Sciences.
