Common Name(s):
English Jamaican Flower Bat

Assessment Information [top]

Red List Category & Criteria: Critically Endangered C2a(i) ver 3.1
Year Published: 2015

This species is known only from Jamaica and has been found recently at only two caves: Marta Tick Cave (1983) and Stony Hill Cave (2010). The population size is estimated to be under 250 mature individuals with fewer than 50 mature individuals at each known subpopulation (roosting caves). There is a continuing decline in mature individuals inferred from the decline in the number of subpopulations since the 1970s. This species is Critically Endangered.

Population [top]

Population:This species was previously known from five or six caves in Jamaica but has been found recently at only two caves, representing two extant subpopulations: Marta Tick Cave (1983) and Stony Hill Cave (2010). Until the 1970s, when it was captured extant at three caves, the largest subpopulation was of 50-60 to perhaps a few hundred individuals concentrated at St. Clair Cave (McFarlane 1986). Recent surveys in 1984 by the Royal Ontario Museum, and in 2005 and 2009-2010 by Andrea Donaldson have failed to detect individuals at St. Clair Cave. Additional surveys at the potentially suitable sites of Riverhead Cave, Mount Plenty Cave and Oxford Cave have also failed to detect this species.

Habitat and Ecology [top]

Habitat and Ecology:This species is colonial and roosts in caves, often together with other bats species. A female with one embryo was caught in January; and a pregnant female captured in June (Genoways et al. 2005). Its diet consists of fruit, pollen, nectar and perhaps insects (Nowak 1999); captive individuals thrived on a diet of bananas, mangoes, papayas and various kinds of canned fruit nectars (Nowak 1999).

Use and Trade [top]

Use and Trade: This species is not used.

Threats [top]

Major Threat(s): There are no recent records from the only known major colony of St. Clair Cave, which contained a few hundred individuals. That cave is not protected and is vulnerable to human disturbance (Nowak 1999). It has a population of feral cats living by the entrance and its surrounding area is unprotected as well.

Conservation Actions [top]

Conservation Actions: Habitat conservation, monitoring of St. Clair Cave and active surveys at other hot caves are recommended.
