The Ansorge bulldog bat ( Chaerephon ansorgei ), ( synonyms : Nyctinomus ansorgei , Tadarida ansorgei and Chaerephon rhodesiae ) is a bat species of the cantilever bat species found in Sub-Saharan Africa .
description
The Ansorge bulldog bat weighs about 20 g and is a medium-sized species of bat. The forearm length is about 42 to 51 mm, the body size including tail between 102 and 116 mm. The fur is gray-brown in color, some individuals are reddish-brown in color. The back side is darker than the belly side, the neck is set off from the lighter belly by a dark brown color. The flight membranes are colored light brown. The head, shoulders and the back side are sometimes speckled white, similar to the spotted bulldog bat . The upper lips are wrinkled, the ears have grown together. The tail protruding from the tail membrane is characteristic of the genus of the cantilever bats.
Systematics & distribution
The exact systematics of the Ansorge bulldog bat is unclear. It was assigned to the spotted bulldog bat. Genetic studies show that the Ansorge bulldog bat forms a clade with the Angola bulldog bat and the Madagascan white-bellied bulldog bat of the genus Pug .
The distribution area extends from South Africa , Mozambique , Zimbabwe and Angola via Kenya , Rwanda , South Sudan to the Democratic Republic of the Congo and Cameroon .
Way of life
Roosts of the species are found in crevices, residential buildings or bridges, where small to medium-sized colony sizes of the species are reached. The number of animals resting together can also be a few hundred animals. Ansorge bulldog bats have been found in tree and shrub savannahs, as well as in rocky mountain regions and steep slopes. They hunt insects in flight, flying fast and high. The diet includes beetles , butterflies and caddis flies .
Etymology & Research History
The specific epithon honors William John Ansorge (1850–1913), who collected the type specimen in 1909 in Malanje in northern Angola. Oldfield Thomas described the holotype in 1913 under the name Nyctinomus ansorgei .
Danger
The IUCN has classified the species as not endangered (“least concern”) due to its large distribution area and the presumably large population size.
