Chrotopterus auritus

Chrotopterus auritus


This bat is the largest in Argentina and is second largest in South America.  It is found in dense forest and thus is difficult to capture.  We managed to catch this species very low in a single net and also in a Harp trap.

It is carniverous and its diet includes small birds, amphibians, reptiles and rodents.  It is believed that it also eats fruit on occasion.

It is large and strong with long woolly dark grey fur, almost unicolour with frosted tips.  It has long well seperated ears that resemble mussel shells with pink interiors and a small tragus.  The forearm is usually over 80mm.
