1954 – First edition of Avian Physiology published by Paul D. Sturkie. The work related mainly to domestic birds and especially poultry, but later editions of the work, now titled Sturkie's Avian Physiology include studies of wild birds.
Brains of an emu, a kiwi, a barn owl, and a pigeon, with visual processing areas labelled. The avian brain is the central organ of the nervous system in birds. Birds possess large, complex brains, which process, integrate, and coordinate information received from the environment and make decisions on how to respond with the rest of the body.
If they fail to find a vacant territory, they usually starve. [11] The juvenile survival rate is unknown, but the annual survival rate for adults is 76.8%. The typical lifespan is five years, [10] but an age of over 18 years has been recorded for a wild tawny owl, and of over 27 years for a captive bird. [18]
The use of bird skins to document species has been a standard part of systematic ornithology. Bird skins are prepared by retaining the key bones of the wings, legs, and skull along with the skin and feathers. In the past, they were treated with arsenic to prevent fungal and insect (mostly dermestid) attack.

Some bird species nest deep in cave systems which are too dark for vision, and find their way to the nest with a simple form of echolocation. The oilbird is the only nocturnal bird to echolocate, [ 79 ] but several Aerodramus swiftlets also utilise this technique, with one species, Atiu swiftlet , also using echolocation outside its caves.
Ibis (formerly The Ibis), subtitled the International Journal of Avian Science, is the peer-reviewed scientific journal of the British Ornithologists' Union. It was established in 1859. [ 1 ] Topics covered include ecology , conservation, behaviour, palaeontology , and taxonomy of birds.
