 during its migrations. The sexual organs of neither specimen were enlarged.

Two males, taken at Noanama December 29 and 30, are evidently winter 

 visitants of this northern form which does not appear to have been before 

 recorded from South America. Their wing measurements are respectively 

 177 and 176 mm. In color they are somewhat brighter than the average 

 specimen of texensis with the black of the crown deeper and of greater extent, 

 differences which I believe to be seasonal. Only spring and summer speci- 

 mens of texensis are available for comparison.

Not uncommon locally in the Subtropical Zone of the Eastern Andes 

 near Bogota, hawking well overhead as does Chordeiles virginianus. I have 

 seen no Peruvian specimens.
