The Peters Bulldog Bat ( Eumops bonariensis ) is a species of bat from the family of the Bulldog Bat , which is native to Central and South America. The species name "bonariensis" is derived from Buenos Aires , where the holotype was collected.
description
Peters bulldog bat is the smallest known bulldog bat with a forearm length of 37 to 49 mm and a total length of 89 to 91 mm . Weight and size are regionally variable. Individuals in Venezuela weigh on average 7–7.4 g, in Bolivia 12–18 g, in Argentina 17.4–18.2 g and in Paraguay 13.7–14.5 g. The males are each slightly larger than the females. The fur color on the back is chocolate brown to cinnamon-colored, the base of the hair is white. The peritoneum is lighter than the fur on the back, with a gray to white tip. The ears are wide and connected in the middle. When placed forward, they protrude beyond the muzzle. The muzzle is relatively wide, with hook-shaped upper incisors. The chin has short bristles, and the upper lip is smooth compared to other bulldog bats.
Way of life
The Peters bulldog bat , like most bats, is nocturnal and feeds primarily on insects. During the day, the animals hide under loose tree bark or in the roofs of buildings. They sometimes share their shelter with other bat species such as Myotis fortidens , the red velvet bat ( Molossus rufus ) and the Bonda velvet bat ( Molossus bondae ). The Peters bulldog bat lives in groups of up to 20 animals, with more females than males in the groups. Thanks to its narrow and long wings, the Peters bulldog bat is a fast flyer that takes up the air above the treetops.
Reproduction
Pregnant females can be found from March to June, with synchronized birth taking place in mid to late June. Pregnant animals were observed regionally in October and November, which is why the species is probably polyestrial . Only one young animal is born at a time. The suckling period is 6–8 weeks.
distribution
The Peters bulldog bat occurs from southern Mexico to central Argentina , although there are no records from Guatemala and Costa Rica . Its population is classified as not endangered by the IUCN thanks to its wide distribution, but the species is under protection in Mexico.
