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.
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.
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. Like in all chordates, the avian brain is contained within the skull bones of the head.
Bird anatomy, or the physiological structure of birds' bodies, shows many unique adaptations, mostly aiding flight.Birds have a light skeletal system and light but powerful musculature which, along with circulatory and respiratory systems capable of very high metabolic rates and oxygen supply, permit the bird to fly.

The study of hormones and physiology in the control of behaviour has also been aided by bird models. These have helped in finding the proximate causes of circadian and seasonal cycles. Studies on migration have attempted to answer questions on the evolution of migration, orientation, and navigation.
The proventriculus is a standard part of avian anatomy, and is a rod shaped organ, located between the esophagus and the gizzard of most birds. [2] It is generally a glandular part of the stomach that may store and/or commence digestion of food before it progresses to the gizzard. [3]
The common raven (Corvus corax), also known as the northern raven, is a large, all-black passerine bird. Found across the Northern Hemisphere , it is the most widely distributed of all corvids . Their Northern range encompasses Arctic and temperate regions of Eurasia and North America, and they reach as far South as Northern Africa and Central ...
