The Australian zebra finch is used worldwide in several research fields (e.g. neurobiology, physiology, behaviour, ecology and evolution) as individuals are easy to maintain and breed in captivity. [12] Zebra finches are more social than many migratory birds, generally traveling in small bands and sometimes gathering in larger groups. [13]
The zebra finch genome was the second bird genome to be sequenced, in 2008, after that of the chicken. [32] The Australian zebra finch uses an acoustic signal to communicate to embryos. It gives an incubation call to its eggs when the weather is hot—above 26 °C (79 °F)—and when the end of their incubation period is near.
Zebra Finch (Taeniopygia guttata) at the Essehof Zoo in Germany. Only male zebra finches sing. [4] Each finch has an individual song. [4] Between the ages of 25 and 90 days old, young zebra finches learn to sing by copying the songs of adults, and sometimes by copying the songs of other juveniles.
The main focus of Zann's ornithological research was the zebra finch,. [2] This work was synthesised in the 1996 book Zebra Finch: A Synthesis of Field and Laboratory Studies, which has been described as his magnum opus. [2] Zann was also known for his studies on the island biogeography of the volcanic island of Krakatau, Indonesia.
In one experimental population of zebra finches, there was increased singing activity by the male after breeding. [9] This increase is positively correlated with the partner's reproductive investment. The female finches were bred in cages with two subsequent males that differed with varying amounts of song output.
One such way that poor diet may affect reproductive success is through song learning. According to the developmental stress hypothesis, zebra finches learn songs during a stressful period of development and their ability to learn complex songs reflects their adequate development. [15]

From the 18th up to the 20th centuries, canaries and finches were used in the UK, Canada and the US in the coal mining industry to detect carbon monoxide. In the UK, this practice ceased in 1986. [6] Typically, the domestic canary is kept as a popular cage and aviary bird. Given proper housing and care, a canary's lifespan ranges from 10 to 15 ...
