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 ...
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.
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 ...
Birds sometimes also form associations with non-avian species. Plunge-diving seabirds associate with dolphins and tuna, which push shoaling fish towards the surface. [203] Some species of hornbills have a mutualistic relationship with dwarf mongooses, in which they forage together and warn each other of nearby birds of prey and other predators ...
The birds typically stay on the wing while handling and ingesting the prey. The more specific term flycatching is used to describe birds that fly out of a perch to capture and insect to return with the prey to a perch before handling the prey. Flush-and-pursue - here the prey is first put into flight before pursuit [3]
These birds create whirlpools by spinning in small, rapid circles. Then they feed on the small insects and crustaceans that rise to the surface. Gender roles are also somewhat unusual within this ...
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.
Insects and birds are able to combine learned landmarks with sensed direction (from the Earth's magnetic field or from the sky) to identify where they are and so to navigate. Internal 'maps' are often formed using vision, but other senses including olfaction and echolocation may also be used.
