Wagner's bonneted bat
Eumops glaucinus is home to a species of bat in the family bulldog bats and in Central and South America. The species name " glaucinus " probably derives from the Greek " glaukos " (silver or glossy).
Description
Eumops glaucinus is with a forearm length of 60.4 to 61.2 mm and a weight of 30.2 to 46.6 g less than Eumops perotis and greater than Eumops maurus. The species is about the size of Eumops auripendulus, but differs by a paler coat color, with a higher contrast between abdominal and back fur. In addition Eumops has glaucinus a wider tragus and a longer and proportionally wider head. The ears are wider than long and protrude forward folded over the snout beyond. Weight and size differ regionally. In Cuba, the average weight of males is 36.6 g, the weigh of females was 37.3 g, in Mexico, the males and females 35.9 g 34.4 g in Venezuela is the average weight of males 33.8 g that of females 32.5 g the wings of Eumops glaucinus are among the narrowest of all the Bulldog bats, which makes the way of a fast flyer over long distances. Eumops glaucinus can be bad maneuver by the fast flying and the relatively large body size in a small space, however. The wingspan is 409-470 mm. The fur color varies from black to gray to brown cinnamon. The hair is two-toned with a light base and a darker top. Males have a throat pouch in contrast to the females, and are slightly larger. In addition, males have a scent gland located at the throat, with which a musky scent is produced, which is probably important for courtship.
Way of life
Eumops glaucinus is like most bats nocturnal and feeds primarily on insects. Their calls are - unusual for bats - so deep that they are audible to the human ear. During the day the animals usually hide in buildings, tree hollows and under bark. The groups are often small and usually consist of one male with several females. The Hide Eumops divided glaucinus sometimes with Molossus molossus, Molossus ater, Tadarida laticaudata and Mormopterus minutus. Known predators of Eumops glaucinus are the American Kestrel and various species of owls. The species is polyöstrisch. It is born per litter in each case only a single cub.
Dissemination
Eumops glaucinus comes from Florida to Peru, Bolivia, Paraguay and northern Argentina before. The stock is classified as unthreatened by the IUCN due to the wide distribution. In Florida, the population is, however, added by habitat loss and potentially by pesticides.
