The visual ability of birds of prey is legendary, and the keenness of their eyesight is due to a variety of factors. Raptors have large eyes for their size, 1.4 times greater than the average for birds of the same weight, [14] and the eye is tube-shaped to produce a larger retinal image. The resolving power of an eye depends both on the optics ...
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.
Birds of prey or predatory birds, also known as (although not the same as) raptors, are hypercarnivorous bird species that actively hunt and feed on other vertebrates ...
Having seen prey, the head is moved from side to side, so that the heron can calculate the position of the prey in the water and compensate for refraction, and then the bill is used to spear the prey.

A new project to protect birds of prey in parts of Sheffield has been launched. Owlthorpe Fields Conservation Group wants to monitor and help boost the population of various raptor species in the ...
Most owls are nocturnal or crepuscular birds of prey. Because they hunt at night, they must rely on non-visual senses. Experiments by Roger Payne [1] have shown that owls are sensitive to the sounds made by their prey, not the heat or the smell.

Predatory birds hunting in pairs have been observed using a "bait and switch" technique, whereby one bird will distract the prey while the other swoops in for the kill. Social behavior requires individual identification, and most birds appear to be capable of recognizing mates, siblings, and young.
