The life expectancy of an Australian zebra finch is highly variable because of genetic and environmental factors. The zebra finch may reach up to five years in its natural environment. If they are kept caged, they normally live for 5 to 9 years but may live as long as 12 years, [ 17 ] with an exceptional case of 14.5 years reported for a caged ...
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 lifespan may be long or short, though the species technically does not "age". Individuals of other species have been observed to regress to a larval state and regrow into adults multiple times. The hydrozoan species Turritopsis dohrnii (formerly Turritopsis nutricula ) is capable of cycling from a mature adult stage to an immature polyp ...
Large mammals develop at an absolute slower rate compared to small mammals. Thus, the large mammal tend have longer gestation periods than small mammal as they tend to produce larger neonate. [18] Large mammals require a longer period of time to attain any proportion of adult mass compared to small mammals. [19]
The global lifespan is nearly a decade longer than the average health span. ... That disparity is even more stark for women, for whom that gap is 2.4 years wider compared to men.
A notable example in birds is the zebra finch. These birds have lateralised brain structures in the face of a common steroid signal, providing strong evidence for a non-hormonal primary sex mechanism regulating brain differentiation.
