Lesson's type of this bird came from the island of Trinidad, 

 and specimens from Venezuela agree with birds from that island. 

 Examples from Bogota have slightly longer bills, a fact noticed by

 named these birds C. oenone longirostris. The glittering blue of the 

 throat is less extensive in birds from Eastern Ecuador, and in the 

 Upper Amazons region (Pobas, &c.) the transition between C. oenone
