All mammalian retinae contain rod photoreceptors for low‐light vision and cone
photoreceptors for daylight and color vision. Most nonprimate mammals have dichromatic …

We investigated the ability of brown long-eared bats to make use of visual cues when
searching for food. By using petri dishes containing mealworms that were subjected to …

Tree cavities are a critical resource for most forest-dwelling bats. Yet, it is not known how
bats search for new sites and, in particular, find entrances to cavities. Here, we evaluated the …

Background Free-flying insectivorous bats occasionally collide with stationary objects they
should easily detect by echolocation and avoid. Collisions often occur with lighted objects …

Optomotor response tests provided visual acuity thresholds in five species of north
European insectivorous bats of the family Vespertilionidae. Individuals of three species of …

The use of ultrasonic echolocation (sonar) in air is seriously constrained by the attenuation
of high frequency sounds and unwanted echoes from the background (called clutter) …

Bats vocalize during flight as part of the sensory modality called echolocation, but very little
is known about whether flying bats consistently call. Occasional vocal silence during flight …

We investigated the detection cues used by the aerial‐hawking bat Eptesicus nilssonii
foraging in a cluttered environment. The bats can detect and attack rapidly moving targets …

We investigated the reactions of four bat species from four different lineages to UV light:
Hipposideros armiger (Hodgson, 1835) and Scotophilus kuhlii Leach, 1821, which use …

The structure of the calls made by the echolocating fruit bat Rousettus aegyptiacus while
flying within a flight tunnel were investigated. Calls are impulsive clicks lasting around 250 …
