The Alexandrine parakeet is one of the largest parakeets, measuring 56 to 62 cm (22 to 24 in) from the top of the head to the tip of the tail and weighing 200 to 300 g (7.1 to 10.6 oz). The tail measures 28 to 35 cm (11 to 14 in).
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.
The human brain contains 86 billion neurons, with 16 billion neurons in the cerebral cortex. [ 2 ] [ 1 ] Neuron counts constitute an important source of insight on the topic of neuroscience and intelligence : the question of how the evolution of a set of components and parameters (~10 11 neurons, ~10 14 synapses) of a complex system leads to ...
Vocal Bird anatomy: Birds produce sounds through the air that passes through the Syrinx, which is shown close up in the bottom right. In order for birds to produce sound, they use an organ located above the lungs called the syrinx , which is composed of tracheal rings, syringeal muscles, Tympaniform membrane, and internal bony structures that ...
The Australian budgerigar, or shell parakeet, is a popular pet and the most common parakeet. Parakeets comprise about 115 species of birds that are seed-eating parrots of small size, slender build, and long, tapering tails. [citation needed] The Australian budgerigar, also known as "budgie", Melopsittacus undulatus, is probably the most common ...

Furthermore, bird brains have two-to-four times the neuron packing density of mammal brains, for higher overall efficiency. The visual and auditory senses are well developed in most species, though the tactile and olfactory senses are well realized only in a few groups.
