Short-eared bat
The short-eared bat (''Cyttarops alecto'') is a bat species from South and Central America. It is found in Brazil, Costa Rica, Guyana and Nicaragua. It is monotypic within its genus.
==Description==
The short-eared bat is a dark-colored sac-winged bat, similar in appearance to ''Saccopteryx'' or ''Peropteryx'', but differentiated by its long, silky fur, low rounded ears, expanded clavicles, grooved tibia, and cranial frontal cup. Forearms range from 45.8 to 47.2 mm long. Skull length ranges from 12.6 to 14.3 mm. Females tend to be somewhat larger than their male counterparts.〔http://www.science.smith.edu/msi/〕
As with all emballonurid bats, short-eared bats use a similar type of echolocation call that consists of a central, narrowband component and one or two short, frequency-modulated sweeps. All calls are multi-harmonic with most energy concentrated in the second harmonic.〔http://onlinelibrary.wiley.com/doi/10.1111/j.1469-7998.2006.00250.x/abstract?deniedAccessCustomisedMessage=&userIsAuthenticated=false〕
