This handsome species is confined to the Caribbean lowlands and lower 

 foot-hills, having the same range as /. prosthemelas, except that it is 

 not found at so high an altitude, seldom going above 1,000 feet. It is 

 more abundant in southeastern Costa Rica than in the northern part, 

 especially along the Sicsola River, where it frequents the wild cane and 

 jungle of wild plantains so common there.

Like the following species, this form is also confined to northwestern 

 Costa Rica, being found only in the Nicoya peninsula and Guanacaste, 

 and more abundantly in the low valley of the Tempisque River. It was 

 first recorded from Costa Rica by Zeledon (An. Mus. Nac. de C. R., I, 

 1887, 112) under the name of Icterus pustulatus, it having been mistaken 

 for that bird. It is not so common as I. pectoralis espinachi, but is found 

 with that bird in the same kind of localities.
