[1] Numerous cases of interspecies friendships among wild and domesticated animals have been reported and documented with photography and video. [1] Domestication of animals has led to interspecies friendships between ...
Around 80–95% of carnivores are solitary and hunt alone; the others including lions, wild dogs, spotted hyenas, chimpanzees, and humans hunt cooperatively, at least some of the time. Cooperative hunting has also been documented in birds of prey and large marine vertebrates such as groupers and moray eels.

Birds sometimes also form associations with non-avian species. Plunge-diving seabirds associate with dolphins and tuna, which push shoaling fish towards the surface. 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.
It is also possibly one of the world's longest-living birds, with a reported lifespan of up to 100 years. Adult males weigh around 1.5–3 kilograms (3.3–6.6 lb); the equivalent figure for females is 0.950–1.6 kilograms (2.09–3.53 lb). The anatomy of the kākāpō typifies the tendency of bird-evolution on oceanic islands.
The corvids ( ravens, crows, jays, magpies, etc.) and psittacines ( parrots, macaws, and cockatoos) are often considered the most intelligent birds, and are among the most intelligent animals in general. Pigeons, finches, domestic fowl, and birds of prey have also been common subjects of intelligence studies.
Birds. Approximately eight percent of bird species are known to regularly engage in cooperative breeding, mainly among the Coraciiformes, Piciformes, basal Passeri and Sylvioidea.
