 varying according to the subspecies. 



Accidental. One record. 



Dr. Eugene Eisenmann (Auk. 1948, p. 606) on August 19, 1947. 

 at Playa Coronado, about 7 kilometers west of Chame, western 

 Province of Panama, found a full-plumaged male resting on a wire 

 fence in an open area among beach cottages. He had it under close 

 observation for the afternoon, and it then disappeared. He was not 

 able to collect the bird, but secured "a tiny but recognizable image on 

 8 mm. Kodachrome motion picture film." 



The species ranges in the north from southwestern California, 

 southwestern Utah and central Texas through Mexico to Nicaragua ; 

 and in South America from northern Colombia and Venezuela to 

 northern Chile and central Argentina, with an outlier on the Galapa- 

 gos Islands. In this range seven or more geographic races are recog- 

 nized, varying somewhat in size and appreciably in depth of color. 

 The record in Panama evidently is that of a stray individual with no 

 clue as to its origin.
