The Martinique oriole mainly forages in the canopy, where it eats fruit, berries and a variety of insects (2) (3). It does not form flocks (3), but still communicates by whistling and by uttering harsh, scolding calls (2). The Martinique oriole also sings a soft, variable, warbling song (8).
Breeding in this species has been recorded from December, but generally starts in February and extends to about July (2) (3). As with related oriole species, the nests of the Martinique oriole look like shallow, woven baskets with a side entrance (5) and are generally built two to four metres above the ground (3), suspended from the underside of a large leaf or from a bunch of leaves at the end of a branch (3) (4) (5).
Once the nest is built, the Martinique oriole usually produces two eggs, or sometimes three (3) (5). These eggs are creamy white with a bluish tinge, and are marked with brown spots at the broad end (5). By mid-July, the eggs have hatched and the breeding pairs are taking care of their new fledglings (3).
The Martinique oriole has not generally been recorded feeding more than 100 metres from its nest, so it seems that this species defends a very small territory in the immediate vicinity of its nesting site (3). In most orioles, it is usually the role of the male to be the guardian of the nest site, while all the family responsibilities, such as feeding and raising the young, are undertaken by the female (6).
