Apart from their shorter wing and tail, I can see no difference between examples of 

 this species from Margarita and other islands off Venezuela and mainland examples; 

 and considering the great range of individual variation in measurements I do not 

 think the supposed island form (L. v. insularis) worth recognizing. A larger scries of 

 island specimens might, however, prove the supposed form to be valid. Specimens 

 from the interior of Venezuela are appreciably darker, and may require subspecific 

 separation.
