s chestnut, olive, and black. Its chest is deep chestnut, lightening to yellower chestnut on the sides and rich yellow on the breast. Its belly is white and the undertail coverts black. Adult females are generally grayish olive, with a grayer head, yellowish olive rump, dusky brown tail, and whitish underparts with dusky streaks. Juveniles resemble adult females, but are duller.Hilty, S. (2020). Hispaniolan Spindalis (''Spindalis dominicensis''), version 1.0. In Birds of the World (J. del Hoyo, A. Elliott, J. Sargatal, D. A.

Behavior

Movement

The Hispaniolan spindalis is a year-round resident throughout its range, but makes local movements depending on the availability of fruit.

Feeding

The Hispaniolan spindalis feeds primarily on fruit of many varieties that it pecks open. It also feeds on flower buds, seeds, tender leaves, and insects. It forages from near the ground in bushes to the tops of fruiting trees. Though it typically forages in pairs or small groups, larger numbers may gather in a heavily fruited tree.

Breeding

The Hispaniolan spindalis' breeding season is mostly May to June ,though some pairs may raise a second brood after. It makes a small cup nest of dry grass in a tree or bush up to about above the ground. The clutch size is three eggs. Nothing else is known about the species' breeding biology.

a few more. The male's dawn song is "a thin, high-pitched whistle, or a prolonged weak, sibilant 'tsee see see see'", sung from an exposed perch or inside dense foliage. Females sing a softer version of the male's song. The species' calls include "a high 'thseep'" and a "more drawn-out 'seeee'".

Status

The IUCN has assessed the Hispaniolan spindalis as being of Least Concern. It has a large range, and though its population size is unknown it is believed to be stable. No immediate threats have been identified. It is considered common. "Utilization of a variety of habitats, including second growth and brushy areas, buffers this species against near-term threats, despite its small world range."
