|Habitat and Ecology:||
The Western Small-footed Myotis has a wide ecological range, from rock outcrops on open grasslands to canyons in the foothills to lower mountains with yellow pine woodlands. Day roosts are variable, but include cracks and crevices in cliffs, beneath tree bark, in mines and caves, and occasionally in dwellings of humans. Night roosts are under a variety of natural and human-induced structures. Hibernacula include caves, mines, and tunnels.
They begin to forage well before full dark, but not as early as the pipistrelle (Pipistrellus hesperus). Presently, not much is k nown about reproductive behavior of this species. Pregnant females have been encountered all through June; a single young is probably common. Scrotal (reproductive) males were captured in August and September. Pregnant females have been captured in mid-June.
The western small-footed myotis feeds early in the evening on small flying insects such as flies, small beetles and winged ants. This species is highly maneuverable in flight, often foraging among boulders, along cliffs or shrubs and trees.
|Major Threat(s):||There are no major threats throughout the species' range.|
|Conservation Actions:||It occurs in several protected areas.|
