Puerto Rican Oriole

Icterus portoricensis

Small36 gForest

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.
