Self-Maintenance

No information.

Agonistic Behavior

Territorial Behavior

Likely territorial, and, as with the other Greater Antillean orioles and most tropical orioles, maintain the territory as a pair (23, 24). Probably not territorial throughout the year (KEO).

Sexual Behavior

Little information.

Mating System and Operational Sex Ratio

Socially monogamous, though no genetic studies of extra-pair mating. Pairs may mate for life.

Courtship, Copulation, and Pair Bond

It is likely that mating pairs interact with one another in claiming and maintaining nesting territory. Bahama Orioles duet, and likely use duets to defend the territory as a pair (3, 23, 25). Once paired, one individual, likely the female, will build the nest while the other individual, presumably the male, will follow their partner closely and sing while their partner searches for nest material (2, 3).

Social and Interspecific Behavior

No Information.

Predation

Kinds of Predators

Predators are poorly known, but may include native snakes, lizards, mammals, as well Merlin (Falco columbarius) and American Kestrel (F. sparverius). These predators could prey on eggs, young, or adults (26, 3). In addition, introduced cats, dogs, and feral hogs could threaten the oriole, especially recent fledglings, and black rat (Rattus rattus) could be a nest predator. More data needed (3).
