The Antillean fruit-eating bat (Brachyphylla cavernarum) is one of two leaf-nosed bat species belonging to the genus Brachyphylla. The species occurs in the Caribbean from Puerto Rico to St. Vincent and Barbados. Fossil specimens have also been recorded from New Providence, Bahamas.

Taxonomy

Three subspecies of B. cavernarum are recognized. B. c. cavernarum is the largest of the subspecies and occurs from St. Croix to St. Vincent. B. c. intermedia is of intermediate size and occurs in Puerto Rico and the Virgin Islands with the exception of St. Croix. B. c. minor occurs in Barbados and is characterized by its small size. [2]

Physical description

The Antillean fruit-eating bat has white to yellow-white hair at the base with darker coloration in the dorsum. Mature individuals measure from 65 to 118 mm (2.6 to 4.6 in) with a forearm length ranges of 51 to 69 mm (2.0 to 2.7 in) in length. The average weight is 45 g (1.6 oz). [3]

Ecology

The Antillean fruit-eating bat occurs in Puerto Rico, the Virgin Islands and the Lesser Antilles north to St. Vincent and Barbados. Individuals roost in a variety of settings, which include unused buildings, caves, dense tree tops, crevices, large wells, and cliffs. Sites without direct sunlight are preferred by the species, although large colonies have been found in sunlit areas. The species occurs in dry arborescent vegetation on St. John. [2]

The Antillean fruit-eating bat's varied diet includes fruits, pollen, nectar, and insects. Fruits consumed in the wild include papaya, mango, Indian almond, manjack ( Cordia spp.), royal palm, and sapodilla. In captivity, the species has been observed consuming bananas, apples, pears, melons, peaches, and the flowers of the Ceiba pentandra (kapok), sausage tree, royal palm, portia tree, and jatobá. Confirmed arthropods consumed include one mite species (Macronyssidae), two batfly species (Streblidae), one tick species (Argasidae), and two bat-mite species (Labidocarpidae). These bats feed in the canopy of the forest and on the ground. [2]

Behavior

The Antillean fruit-eating bat moves out from the roost synchronically one hour after sunset and 20 minutes after the Jamaican fruit bat (Artibeus jamaicensis). This synchronization is also evident when returning to the roosts, which happens just before the break of dawn. [2]

The New World leaf-nosed bats (Phyllostomidae) are found from southern North America to South America, specifically from the Southwest United States to northern Argentina. They are ecologically the most varied and diverse family within the order Chiroptera. Most species are insectivorous, but the phyllostomid bats include within their number true predatory species and frugivores. For example, the spectral bat, the largest bat in the Americas, eats vertebrate prey, including small, dove-sized birds. Members of this family have evolved to use food groups such as fruit, nectar, pollen, insects, frogs, other bats, and small vertebrates, and in the case of the vampire bats, even blood.

The Egyptian fruit bat or Egyptian rousette is a species of megabat that is found in Africa, the Middle East, the Mediterranean, and the Indian subcontinent. It is one of three Rousettus species with an African-Malagasy range, though the only species of its genus found on continental Africa. The common ancestor of the three species colonized the region in the late Pliocene or early Pleistocene. The species is traditionally divided into six subspecies. It is considered a medium-sized megabat, with adults weighing 80–170 g (2.8–6.0 oz) and possessing wingspans of approximately 60 cm (24 in). Individuals are dark brown or grayish brown, with their undersides paler than their backs.

The Puerto Rican tanager is a small passerine bird endemic to the archipelago of Puerto Rico. It is the only member of the genus Nesospingus and has historically been placed in the tanager family, but recent studies indicate it as either belonging in its own family Nesospingidae or as being a member of Phaenicophilidae. Its closest relatives are likely the spindalises. The Puerto Rican tanager is known to locals as llorosa, which means 'cryer'.

The fauna of Puerto Rico is similar to other island archipelago faunas, with high endemism, and low, skewed taxonomic diversity. Bats are the only extant native terrestrial mammals in Puerto Rico. All other terrestrial mammals in the area were introduced by humans, and include species such as cats, goats, sheep, the small Indian mongoose, and escaped monkeys. Marine mammals include dolphins, manatees, and whales. Of the 349 bird species, about 120 breed in the archipelago, and 47.5% are accidental or rare.
