Some bats prey on other vertebrates, such as fish, frogs, lizards, birds and mammals. [48] [169] The fringe-lipped bat (Trachops cirrhosus,) for example, is skilled at catching frogs. These bats locate large groups of frogs by tracking their mating calls, then plucking them from the surface of the water with their sharp canine teeth. [170]
The three species of sanguinivorous bats belong to the subfamily Desmodontinae. These bats are characterized by relatively high wing-loading and short or average wingspans. [27] The high wing-loading allows them faster flight speeds, which is advantageous when they have to commute long distances from their roosts to find prey. [27]
Indiana bats moved to the alternate roost during periods of heavy rain and colder ambient temperatures during fall in Missouri, but chose to roost in the primary snag during inclement weather in the spring. These differences may be attributed to variation in the heat-retention capabilities of the trees at different times of the year. [22]
Without predators, the lesser short-tailed bat evolved to survive in both aerial and ground habitats. Like other bats, in the air, they catch food by using echolocation to detect the location of prey. The lesser short-tailed bats forage on the ground by moving around on their limbs, sourcing prey by using olfaction. [16]

Experiments on blue jays suggest they form a search image for certain prey.. Visual predators may form what is termed a search image of certain prey.. Predators need not locate their host directly: Kestrels, for instance, are able to detect the faeces and urine of their prey (which reflect ultraviolet), allowing them to identify areas where there are large numbers of voles, for example.
