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 ...
This is a list of maximum recorded animal lifespans in captivity.Only animals from the classes of the Chordata phylum are included. [1] On average, captive animals (especially mammals) live longer than wild animals.
Zebra finches are more social than many migratory birds, generally traveling in small bands and sometimes gathering in larger groups. [13] They are one of the bird species that is able to learn new vocalizations and have become a dominant model species in the study of vocal learning . [ 14 ]
Different social environments during early life can have an effect on the level of adult neurogenesis in the HVC. Male zebra finches that are housed separately during their early life show decreased adult neurogenesis in the HVC and Area X compared to socially reared male zebra finches during the sensitive period.

One specimen has been estimated to be 1,550 years old. [70] A specimen, "Ming" of the Icelandic cyprine Arctica islandica (also known as an ocean quahog), a mollusk, was found to have lived 507 years. [71] Another specimen had a recorded lifespan of 374 years. [72]

The average life expectancy in the U.S. is 77.5 years, according to the Centers for Disease Control and Prevention. But Americans outlive their health spans by 12.4 years, the study found.
The results of Secora et al. (2012) of interhemispheric switching as an explanation for this phenomenon in Bengali finches is seen to a degree in zebra finches, however, they suggest it may be far more pronounced in Bengali finches. [9] The Bengali and zebra finch are closely related oscine songbirds that have been pivotal to the study of song ...
