Puerto Rican Oriole
Icterus portoricensis
Males and females are similar in size and color. Males weigh about 41.0 grams and females weigh about 36.6 g. The average wingspan of males and females is 96.9 and 92.1 mm, respectively. In 2008, Hofmann, Cronin, and Omland, conducted a study that showed there is little color difference in the feathers between the males and females of many tropical orioles, including the Puerto Rican oriole. This means that males and females both have elaborate colors, in contrast many temperate-zoned birds have brightly colored males and dull colored females.

Red-bellied Grackle
Hypopyrrhus pyrohypogaster

The sexes are similar in appearance being entirely black apart from a red belly and red under-tail coverts. The bill is conical in shape and the irises are white or yellow. When held in the hand it is possible to see that the feathers of the head, neck and throat have shiny, naked shafts and thick, narrow webs.
