=Feeding=
=Breeding=
The Antillean palm swift's breeding season on Cuba is May to July, and on Hispaniola, from March to May. It makes a hanging pouch nest of plant fibers and feathers glued together with saliva and hung on the outside of a dead drooping palm frond. It nests in small colonies. The clutch size is two to five; both parents incubate the eggs and care for nestlings.

Status
The IUCN has assessed the Antillean palm swift as being of Least Concern. It has a large range, and though its population size is not known it is believed to be stable. No immediate threats have been identified. "This swift is adaptable to living around human habitations, and the planting of decorative palms provides nest sites for these birds."
