Origin
Icterus pectoralis is native to southern Mexico and Central America. Spot-breasted orioles were introduced to the United States in southern Florida.

Life Cycle
I. pectoralis are primarily bright orange to reddish in plumage coloration with black on their tails, wings, and throat as well as white patches on the wings. As their name implies, their defining feature is black spots on the breasts. No sexual dimorphism occurs. I. pectoralis is territorial and thought to be socially monogamous. Individuals are approximately 4.7 in. (12 cm) in length and weigh 1.7 oz (49 g). Spot-breasted orioles have distinct hanging nests approximately 20 in. in length and 5 in. wide at the base. Females incubate an average of 3 eggs per nesting season with the possibility of 2 clutches per season in Florida. The feeding of chicks is done by both parents.

Distribution
I. pectoralis populations occur in urban areas from Palm Beach to Miami, Florida.

Control Efforts
There are no known positive or negative economic issues caused by I. pectoralis in the United States.
