For example, statistics show that captive finches generally have a 2.5 times greater lifespan than wild ones.Ĭompared to wild finches who live for about 4 to 7 years, the captive ones can survive for about 12 to 20 years. How Long Do Finches Live In Captivity And In The Wild?ĭifferent research has proved that pet finches have a longer lifespan than that living in the wild. Some species, like the European Goldfinch, are found to live for more than 27 years which may have shocked you. The wild ones have a lifespan of 4 to 7 years, whereas captive finches can stay for more than ten years. Most of the research done to date glorifies that finches in captivity survive more than ones living in the wild.

However, in this part of the study it was not clear if telomere length was the cause between the father's age and offspring longevity association. For example, only five percent of birds fathered by an older male survived past one year, but nearly 80 percent of birds with a young father survived past one year. However, the effect was stronger in birds with an older father. Results revealed that having an older mother and an older father resulted in earlier death for the birds.
The offspring of these matches were then followed and their age of death documented. For example, age combinations included young females bred with older males and older females bred with older males. To further investigate the effect that parental age had on offspring longevity, the team then bred 44 pairs of birds with different age combinations. Embryos fathered by older finches had telomeres that were 10 percent shorter than those of embryos fathered by the four day old finches, The Scientist reported.

The eggs were incubated for several days before the researchers analyzed the embryos inside. Breeding resulted in a total of 139 eggs. The birds typically live between five to eight years, so these were considered older males. In the study, the team bred 32 middle aged female zebra finches with 16 four month old males and then 16 four year old males, The Scientist reported. Telomere length is a good indication of longevity, as when they get too short cells that can no longer function properly. They protect our chromosomes from damage during cell division. Telomeres are often referred to as the "caps" at the end of our DNA. Researchers looked at the telomeres of zebra finch embryos conceived by either young or older male finches. The findings may help researchers better understand the association between father's age and children's longevity in humans. The chromosomes of finches born from older fathers have traits associated with a shorter life expectancy than the finches conceived by younger dads, revealed a new study published online in the Proceedings of the Royal Society B.
