Yellow-throated big-eared bat
|Yellow-throated big-eared bat|
The yellow-throated big-eared bat or orange-throated bat(Lampronycteris brachyotis) is a species of bat from South and Central America, where it ranges from southern Mexico to Brazil. It is monotypic within the genus Lampronycteris. A frugivore and insectivore, it is found in lowland forest up to an elevation of 700 m. Activity is greatest in the first two hours after sunset, and peaks again after midnight.
It is characterized as a "medium-sized" leaf-nosed bat. Its ears are short and pointed. The nose-leaf is relatively small. Its dorsal fur is dark brown or orange brown, while its ventral fur is reddish-yellow or orange. Individuals weigh 9–15 g (0.32–0.53 oz) and have forearm lengths of 39–43 mm (1.5–1.7 in). Its dental formula is 220.127.116.11 for a total of 34 teeth.
Biology and ecology
It is primarily an insectivore but will also consume fruit, nectar, and pollen. It is nocturnal, roosting in sheltered places during the day such as caves, mines, hollow trees, and archaelogical ruins. It generally roosts in small colonies consisting of 10 or fewer individuals, though a colony of 300 individuals was once documented in Mexico.
Range and habitat
It is found in several countries in Central and South America. Its range includes: Belize, Brazil, Colombia, Costa Rica, French Guiana, Guatemala, Guyana, Mexico, Nicaragua, Panama, Peru, Suriname, Trinidad and Tobago, and Venezuela. It is generally found in lowland areas below 150 m (490 ft) above sea level, though it has been documented at up to 700 m (2,300 ft) above sea level.
