Read interesting grey long-eared bat facts like conservation status, distribution, range, and habitat.

A rare form of grey long-eared species is found in Britain and is so similar to the brown long-eared species that it is difficult to differentiate between the two. While talking about the morphological features of grey long-eared bats, the fur is usually long. Its dorsal fur is medium to dark grey with a hint of brown color, whereas the ventral fur is a pale grey. Its ears are longer than 1.18 in (30 mm) and around three-quarters of the length of the head and body. The only feature that distinguishes grey long-eared bats from other bats is the width of the tragus. The tragus of grey long-eared bats is 0.1 in (5 mm) at its widest point. Another ambiguous point between the two species of bats is that the brown long-eared juveniles have grey fur until about a year. The only similarity between both species of bats is that they fold their ears beneath their wings during sleep and the period of hibernation. During this time, only the tragus gets exposed. Their flight is usually near the ground level. Due to their broad wings, they are highly maneuverable. Their prominent feature is their long ears which make them recognizable even as they fly by.
