Nectar- and pollen-eating bats can hover, in a similar way to hummingbirds. The sharp leading edges of the wings can create vortices, which provide lift. The vortex may be stabilized by the animal changing its wing curvatures. [62] Roosting and gaits [ edit ] Group of megabats roosting Teeling, E. C.; Madsen, O; Van Den Bussche, R. A.; de Jong, W.

During hibernation, bats enter a torpid state and decrease their body temperature for 99.6% of their hibernation period; even during periods of arousal, when they return their body temperature to normal, they sometimes enter a shallow torpid state, known as "heterothermic arousal". [114] Some bats become dormant during higher temperatures to keep cool in the summer months. [115]

Bats also possess a system of sphincter valves on the arterial side of the vascular network that runs along the edge of their wings. When fully open, these allow oxygenated blood to flow through the capillary network across the wing membrane; when contracted, they shunt flow directly to the veins, bypassing the wing capillaries. This allows bats to control how much heat is exchanged through the flight membrane, allowing them to release heat during flight. Many other mammals use the capillary network in oversized ears for the same purpose. [110] Torpor [ edit ] A tricoloured bat ( Perimyotis subflavus) in torporLicht, Paul; Leitner, Philip (1967).

Microbats make use of magnetoreception, in that they have a high sensitivity to the Earth's magnetic field, as birds do. Microbats use a polarity-based compass, meaning that they differentiate north from south, unlike birds, which use the strength of the magnetic field to differentiate latitudes, which may be used in long-distance travel. The mechanism is unknown but may involve magnetite particles. [102] [103] Thermoregulation [ edit ] Thermographic image of a bat using trapped air as insulation Maina, J. N. (2000).
