Vampire bats were not studied in their natural habitats until about 1935. During predation, bats first spend a few minutes in the air circling the target prey, eventually landing on the back or neck crest of the animal, and sometimes the ground. They then proceed to search for a suitable spot to bite, which can take seconds to minutes, and ...
Common vampire bats have good eyesight. They are able to distinguish different optical patterns and may use vision for long-range orientation. [3] These bats also have well-developed senses of smell and hearing: the cochlea is highly sensitive to low-frequency acoustics, and the nasal passages are relatively large. [3]
A vampire bat can only survive about two days without feeding, yet they cannot be guaranteed of finding food every night. This poses a problem, so when a bat fails to find food, it will often "beg" another bat for food. A "donor" bat may regurgitate a small amount of blood to sustain the other member of the colony.

Rooftops give the maternity colonies access to cooler spots on warmer days and warmer spots at other times. This was discovered by the use of different coloured bat boxes and seeing how commonly each was used. Although black bat boxes could get too warm they were most frequented, suggesting a preference for warmer temperatures.
Like other microbats, these bats employ echolocation when flying. [22] Lesser short-tailed bats emit sounds in the range of 20-40 kHz. Each call lasts between seven and nine milliseconds. [23] Echolocation does not work as efficiently while foraging on the ground, because the echoes can be disrupted by the forest floor and anything occupying ...
Like many bat species, C. perspicillata has a long lifespan, being able to live up to ten years. [3] Mortality rates for bats is 53% in the first two years of life, but that goes down to 22% in the following years. [3] In this species, there doesn't seem to be a difference in the average lifespans of males as opposed to females. [3]
