Murciélago-bigotudo de Parnell

<em>Pteronotus parnellii</em>, the common mustached bat or Parnell's mustached bat, is a Neotropical bat in the family Mormoopidae. Named for the distinctive fleshy lip projections around its muzzle, this insectivorous species typically roosts in large colonies in caves and hollow trees across its range in South and Central America and the Caribbean. <em>Pteronotus parnellii</em> is a highly specialized echolocator, emitting constant-frequency echolocation calls that are finely tuned for detecting fluttering insect prey in cluttered vegetation. Its geographic range extends through Colombia, Venezuela, and neighboring countries in tropical and subtropical lowland forests and scrublands. The species is currently assessed as Least Concern by the IUCN, reflecting its broad distribution and tolerance of varied habitats, though local populations may face pressure from cave disturbance and deforestation. Biological traits such as lifespan, body size, and diet remain poorly documented across the full range of this species at a population level. <em>Pteronotus parnellii</em> plays an important ecological role as an insect predator, contributing to natural pest suppression in agricultural and forest ecosystems throughout its Neotropical range.
