Discover the Secrets of the Adaptations and Behaviors of Antillean Palm Swifts

Antillean Palm Swift, also known as Tachornis phoenicobia, is a bird species that belongs to the family Apodidae. They are small in size, measuring only 10 centimeters in length and weighing around 8 grams.

These swifts are known to inhabit various parts of the Caribbean, including Cuba, Jamaica, and Hispaniola. In this article, we will provide you with an overview of the identification and plumages of the Antillean Palm Swift.


Field Identification

Antillean Palm Swifts are small, black-brown swifts with a short, forked tail. They have a wingspan of around 27 centimeters and a curved outer primary flight feather.

They have distinctly long, thin wings, and their feet are tiny, which makes them unsuitable for standing or hopping. Swifts, in general, can only cling to vertical surfaces, indicating their arboreal lifestyle.

In flight, they move their wings rapidly, and their wings produce a distinctive, swooshing sound.

Similar Species

It is important to differentiate Antillean Palm Swifts from other species such as Vaux’s Swifts and Chimney Swifts. In comparison to Antillean Palm Swifts, Vaux’s Swifts have a longer tail and slimmer body.

Furthermore, they have a pale, grayish-white throat and belly. On the other hand, Chimney Swifts are brown in color and have a “cigar-shaped” body.

They also have visible spines on their tails, which make them easy to identify.


As previously mentioned, Antillean Palm Swifts have black-brown plumages with a short, forked tail. Their feathers are shiny and slightly iridescent, giving them a sleek appearance.

They also have a distinctive white rump, which is visible when they are in flight. This feature serves as an excellent field identification technique.


Birds molt their feathers to grow new ones, and Antillean Palm Swifts are no exception. They undergo two molts each year: a complete molt and a pre-basic molt.

The complete molt occurs between June and September, when the birds replace all their feathers. The pre-basic molt takes place during February and March, when Swifts change their feathers for the winter period.

In conclusion, Antillean Palm Swifts are fascinating little birds. Their distinct long, thin wings, and small feet make them suitable for clinging to vertical surfaces.

Through this article, we have provided you with an overview of the bird’s identification and plumages, including their molts. Paying close attention to these features can help bird enthusiasts observe and identify Antillean Palm Swifts in the wild.

The Antillean Palm Swift (Tachornis phoenicobia) is a fascinating bird species that is commonly found in the Caribbean islands of Jamaica, Hispaniola, and Cuba.

In this article, we will discuss the different aspects of their behavior, including locomotion, self-maintenance, agonistic and sexual behavior, and breeding. We will also delve into their demographics and population trends over time.



Antillean Palm Swifts are well-adapted for long periods of flight, which they use to forage for food or travel between breeding sites. They have long, narrow wings that allow them to fly swiftly, and their tiny feet make them less cumbersome in the air.

When resting, they cling to vertical surfaces, such as palm trees, using their sharp claws to grip onto their perches.


Antillean Palm Swifts maintain their feathers regularly by preening and oiling them with the preen gland secretions. They spread the oil evenly across their feathers to waterproof them and keep them free of parasites.

They also use dust baths to maintain their plumage by using the dust to absorb oils and excess moisture.

Agonistic Behavior

Antillean Palm Swifts are usually solitary, but sometimes, aggression can occur between them. They have a hierarchical social structure with dominant birds actively defending their territory from competitors.

Aggressive behavior can involve body contact, chases, or vocalization.

Sexual Behavior

Antillean Palm Swifts are monogamous and mate once per year. During the breeding season, males will perform aerial displays regularly to attract a mate.

Males will also select a potential nest site, and if a female is interested in the site, she will accept the male as her mate and start building the nest.


Antillean Palm Swifts breed between March and June, which is the rainy season in the Caribbean. Females lay 1-2 eggs in shallow nests made of moss, feathers, and other soft materials, which are built by both parents.

After 18-22 days of incubation, the eggs hatch, and the chicks grow rapidly, taking their first flight in approximately five weeks.

Demography and Populations

Little is known about the population trends of Antillean Palm Swifts. However, they are classified as a species of Least Concern by the International Union for Conservation of Nature (IUCN) due to the apparent stability of their populations.

However, as their habitat is rapidly declining, their populations and demographics can be affected by the quality of the environment they live in.
