Franquet's Epauletted Bat

The Franquet's epauletted fruit bat was first described by Robert F. Tomes in 1860 and classified as Epomophorus francqueti from a specimen in the French National Collection forwarded to it by a Dr Franquet of the French Imperial Navy. The habitat location has been mentioned as "Gaboon". The type location is considered to be as Gabon and no subspecies have been recognised. It is a tail-less brown bat with large white epaulettes, white on the middle of the belly and white earspots. It has a head and body length 165 to 180 mm (6.5 to 7.1 in) and forearm length 74 to 102 mm (2.9 to 4.0 in). The body weight of a female bat ranges from 56 to 115 g (2.0 to 4.1 oz) while that of a male bat ranges from 59 to 160 g (2.1 to 5.6 oz). Male bats have two pharyngeal sacs and shoulder pouches lined with glandular membranes. The epaulettes are due to white hair tufts and are prominent in dried laboratory specimens but may be concealed due to the shoulder pouches being contracted in the case of live bats. The epaulettes help spread olfactory cues by dispersing chemicals produced in the glandular shoulder patches.

Franquet's epauletted fruit bat ranges from Ivory Coast to South Sudan and south to Angola and Zambia. Specifically, it is found in Angola, Benin, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Ivory Coast, Ghana, Nigeria, Rwanda, South Sudan, Tanzania, Togo, Uganda, and possibly Zambia. Reports of this species from Equatorial Guinea appear to be erroneous. Its natural habitat are subtropical or tropical dry, moist lowland, and mangrove forests, subtropical or tropical swamps, and dry savanna.

The adult male Franquet's bat has a bony voice box and emits a high pitched call which is heard throughout the night. This call may last several minutes and sounds like "kyurnk" at close range and a musical whistle from far off. Franquet's bats, like many other large frugivorous bats, cannot echo-locate. The males frequently perch by night in favourite trees generally a 100 meters or so apart and call noisily, display the epaulettes prominently while calling. The males increase their call rate in the presence of females; one male has been recorded as emitting 10,000 calls over a period of just three hours on one evening. The calls of such males can be heard as far as a mile off and have been compared to a "flock of excited crows". Franquet's bats are found in both forests and open country, roosting in trees and bushes by day when they are quite alert, often at a height of 4 to 6 m (13 to 20 ft). Not being gregarious, they are found either alone or in groups of two or three. Franquet's bat, like other epauletted fruit bats feeds mainly by night on fruit, nectar and the petals of certain flowers, making much noise while feeding. Suction, rather than mastication, appears to be the primary mode of consumption of food by Epomops bats. The extensible lips protrude and engulf the fruit. The hard rind is then pierced with the canines and premolars. …
