Domestic Birds

Common Myna (Animal of India, Australia)

He includes croaks, squawks, chirps, clicks and whistles, and the bird often fluffs its feathers and bobs its head in singing. The Common Myna screeches warnings to its mate or other birds in cases of predators in proximity or when its about to take off flying. Common Mynas are popular as cage birds for their singing and "speaking" abilities. Before sleeping in communal roosts, mynas vocalise in unison, which is known as "communal noise"

The Common Myna uses the nests of woodpeckers, parakeets, etc. and easily takes to nest boxes; it has been recorded evicting the chicks of previously nesting pairs by holding them in the beak and later sometimes not even using the emptied nest boxes. This aggressive behaviour is considered to contribute to its success as an invasive species.

During the breeding season, the daytime activity-time budget of Common Myna in Pune in April to June 1978 has been recorded to comprise the following: nesting activity (42%), scanning the environment (28%), locomotion (12%), feeding (4%), vocalisation (7%) and preening-related activities, interactions and other activities (7%).

Barbary Dove (Animal of North Africa)

The coo of the ringneck dove is created by musclus that vibrate air sent up from the dove's lugns. These muscles belong to the fastest known class of vertabrite muscles, contracting as much as ten times faster than muscles vertebrates use for running. This class of muscles is usually found in high speed tissue such as a  tail. Ringneck doves are the first bird species to have been found to have this class of muscle.

However, it has been observed or theorized that individual doves are unlikely to fare well. Ringneck Doves released to the wild cannot readily survive, as they are not equipped to live wild in most climates, have no natural fear of , and have never learned to distinguish "natural" foods. It has been observed that at least the female can not only coo but emit a high pitched laughing sound. [Muns Baare July 2010]

Ringneck Doves have been domesticated for 2000 to 3000 years.They are easily kept, and long-lived, in captivity, living for up to 12 years, and are noted for their gentle nature. In recent years they have been used extensively in biological research, particularly into the hormonal bases of , because their sequences of courtship, mating and parental behaviour have been accurately described and are highly consistent in form. Dove fanciers have bred them in a great variety of colours; the number of colours available has increased dramatically in the latter half of the twentieth century, and it is thought that this has been achieved by interbreeding with S. roseogrisea. Some of these doves carry a mutation that makes them completely white.
