occurs (regularly, as a native taxon) in multiple nations
Regularity: Regularly occurring
Type of Residency: Year-round
Global Range: RESIDENT: Pacific lowlands from Colima south to central Costa Rica and locally in interior valleys and on the Caribbean slope of Guatemala and Honduras. INTRODUCED: established in southeastern Florida (AOU 1983).
Length: 24 cm
Comments: Open woodland, deciduous forest, arid scrub, brushy areas (AOU 1983). In Florida: open woods, country, and gardens where tall trees present. BREEDING: Nests at end of branch in tall tree, often in yuccas in native range.
Habitat and Ecology
Non-Migrant: Yes. At least some populations of this species do not make significant seasonal migrations. Juvenile dispersal is not considered a migration.
Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: No. No populations of this species make annual migrations of over 200 km.
Comments: Largely a fruit and nectar feeder (Terres 1980).
Life History and Behavior
Lifespan, longevity, and ageing

Red List Criteria
It is a mid-sized songbird and generally typical oriole. It is bright orange overall with a black bib and black spotting on the sides of the breast. The sexes are similar looking generally but females and juveniles are olive-green on the back and tail, dusky wings, and little or no black on face, throat, or breast. Adults measure 21–24 cm (8.3–9.4 in) in length. Males weigh around 50 g (1.8 oz) on average, while females weigh 45 g (1.6 oz). The wing bone measures 8.8–11.4 cm (3.5–4.5 in), the tail measures 8.5–11.2 cm (3.3–4.4 in), the culmen measures 1.9–2.4 cm (0.75–0.94 in) and the tarsus measures 2.6–3 cm (1.0–1.2 in).
The spot-breasted oriole ranges only on the Pacific side of Central America. An introduced breeding population also exists on the Atlantic coast of southern Florida. The population is considered to be established enough to be "countable" for birdwatchers by the ABA.
