The anatomy of bird's respiratory system, showing the relationships of the trachea, primary and intra-pulmonary bronchi, the dorso- and ventro-bronchi, with the parabronchi running between the two. The posterior and anterior air sacs are also indicated, but not to scale. Inhalation–exhalation cycle in birds.
Diagram of a bird cone cell By far the most abundant cone pigment in every bird species examined is the long-wavelength form of iodopsin , which absorbs at wavelengths near 570 nm. This is roughly the spectral region occupied by the red- and green-sensitive pigments in the primate retina, and this visual pigment dominates the colour sensitivity ...

Kea can solve logical puzzles, such as pushing and pulling things in a certain order to get to food, and will work together to achieve a certain objective.
HVC (avian brain region) The HVC in the context of the song-learning pathway in birds. [1] HVC (formerly, hyperstriatum ventrale, pars caudalis ( HVc ), and high vocal center) is a nucleus in the brain of the songbirds (order passeriformes) necessary for both the learning and the production of bird song. It is located in the lateral caudal ...
The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It consists of nervous tissue and is typically located in the head ( cephalization ), usually near organs for special senses such as vision, hearing and olfaction. Being the most specialized organ, it is responsible for ...
