Savi's pipistrelle

Savi's pipistrelle primarily exhibit nocturnal and aerial behavior, engaging in insectivorous feeding habits. They're generally solitary but may form small groups in winter. Interestingly, this species displays vertical hanging during rest and uses echolocation for navigation and prey detection. Unlike many counterparts, savi's pipistrelle do not undergo hibernation, but may become torpid to conserve energy.

Savi's pipistrelle is native to the Mediterranean region of southern Europe, North West Africa, the Middle East, central Asia, Mongolia and northern Japan. It also occurs in the Canary Islands, Switzerland and Austria and has been recorded from Slovakia. It mainly occurs in mountainous regions where it is found at altitudes of up to 2,500 metres (8,200 ft). It favours bushy slopes with clumps of trees, scrubland, cliffs, gorges and ruins. In the summer it hides by day under the bark of trees, in rock clefts, in hollow trees, in holes in walls, in buildings under rafters and roof tiles. In winter it seeks more protected places to roost such as near the entrances of caves, in underground vaults and in deep rock crevices, where it normally hides alone.
