The narrow-footed feather-tail glider ( Acrobates pygmaeus ) is a species of marsupial from the family of the dwarf glider ( Acrobatidae), which occurs in southeast Australia from the McPherson Range on the border of New South Wales and Queensland to Victoria .
description
Narrow-foot, feather-tail gliders reach a head body length of 50 to 70 millimeters, have a 60 to 75 millimeter long tail and reach a weight of 8 to 18 grams. Males are on average about 10% larger than females and their size decreases from south to north of the range ( Bergmann's rule ), so that the males in the north of the range are the same size as the females. The tail has short, stiff hairs on both sides that give it a feathery look. In young animals it is shorter than in older animals relative to the body length. The back, the top of the head, the top of the limbs and the sliding membrane are brownish to dark gray. The underside and a 1 to 2 millimeter wide zone on the edge of the tail are cream-colored or gray. Ears and toes are only sparsely hairy. From its sister species, the broad- footed feather-tail glide bag ( Acrobates frontales ), the narrow-foot feather-tail glide bag differs only in the shape of the balls of the feet, which are round and of the same length as the width, while the broad-footed feather-tail glide bag is heart-shaped that are wider than they are long. The furrows between the balls of the feet are only indistinctly formed in the narrow-foot, feather-tail sliding bag.
Habitat and behavior
Narrow-footed feather-tail gliders live in closed and open forests from sea level to heights of 1200 meters. In large parts of the distribution area it occurs sympatricly with the broad-footed feather-tail glide bag. More detailed studies on nutrition, behavior and reproduction, which distinguish the two species, are not yet available. More in the article on the genus .
