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 usually will feed on the neck or flank.
Common noctule bats mainly eat beetles, moths and winged ants. It is known for its high-flying foraging technique, often hunting at altitudes of up to 1,000 meters. Nyctalus noctula uses echolocation to detect prey, emitting high-frequency
The term echolocation was coined by 1944 by the American zoologist Donald Griffin, who, with Robert Galambos, first demonstrated the phenomenon in bats. [1] [2] As Griffin described in his book, [3] the 18th century Italian scientist Lazzaro Spallanzani had, by means of a series of elaborate experiments, concluded that when bats fly at night, they rely on some sense besides vision, but he did ...
The delay of the returning echoes allows the bat to estimate the range to their prey. [93] In high-duty cycle echolocation, bats emit a continuous call and separate pulse and echo in frequency using the Doppler effect of their motion in flight. The shift of the returning echoes yields information relating to the motion and location of the bat's ...
A bat wing, which is a highly modified forelimb. Bats are the only mammal capable of true flight. Bats use flight for capturing prey, breeding, avoiding predators, and long-distance migration. Bat wing morphology is often highly specialized to the needs of the species. This image is displaying the anatomical makeup of a specific bat wing.

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.
