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 .
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.
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 ...
Hummingbirds are birds native to the Americas and comprise the biological family Trochilidae. With approximately 366 species and 113 genera, [1] they occur from Alaska to Tierra del Fuego, but most species are found in Central and South America. [2] As of 2024, 21 hummingbird species are listed as endangered or critically endangered, with ...
The triune brain is a model of the evolution of the vertebrate forebrain and behavior, proposed by the American physician and neuroscientist Paul D. MacLean in the 1960s. The triune brain consists of the reptilian complex ( basal ganglia ), the paleomammalian complex ( limbic system ), and the neomammalian complex ( neocortex ), viewed each as ...
Along with crows, ravens, and jays (family Corvidae), parrots are considered the most intelligent of birds. The brain-to-body size ratio of psittacines and corvines is comparable to that of higher primates. [86] Instead of using the cerebral cortex like mammals, birds use the mediorostral HVC for cognition.
Anatomical terms of neuroanatomy. [ edit on Wikidata] The cerebellum ( pl.: cerebella or cerebellums; Latin for "little brain") is a major feature of the hindbrain of all vertebrates. Although usually smaller than the cerebrum, in some animals such as the mormyrid fishes it may be as large as it or even larger. [ 1]
Bird intelligence. Kea ( Nestor notabilis) are known for their intelligence and curiosity, both vital traits for survival in the harsh mountain environment that is their home. 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.
