[2] These birds are identified as slim, long billed and largely black with flashes of russet orange on the shoulders, rump, belly and vent.

This particular species is roughly 20 to 22 cm in head to body length with an average mass of 36.9 gram (both male and female measurements are included).

[2][4] Typical of the Icterid family, St. Lucia orioles exhibit wide range of foraging adaptations.

They produce a typical hanging oriole nest, which is basket shaped, and woven from plant fibers.

[5] The song of the St. Lucia orioles is a series, composed of two second long varied whistles played in a sequence.

Potential hazards include habitat loss, pesticide spraying, and parasitism by shiny cowbirds (Molothrus bonariensis).
