![]() Setting upĪ birdcageis the perfect place for your new pet to perch or, if you are introducing a flock of new friends to your home, an aviary. If you have enough space it’s definitely recommended that you parent a couple of finches, mixed gender or same sex, or even more than two. Like most birds, finches love to live with their own kind. While they are usually hands-off pets, a finch is the perfect companion animal and has been known to perch on your finger. Not usually ones to stay quiet, your finch will liven up your life for up to 15 years. If you’re looking for a pet that will bring personality, beauty and song into your house without extensive upkeep, a finch is the perfect new friend for you. Home – 73cm x 46cm x 46cm cage Care and maintenance So you’ve welcomed a finch into your family – congratulations! Discover everything you need to know about how to care for your new pet finch, including advice on grooming, health care, nutrition and routine.ĭiet – Birdseed, crumbles, fruits and veggies Follow LiveScience for the latest in science news and discoveries on Twitter and on Facebook.

It's not clear why youthful telomere length - measured when the birds were 25 days old, still juveniles that had not yet reached sexual maturity - appears to predict their life span, Monaghan said. "It could be multifaceted and there could be many different causes, we are not saying (loss of) telomeres are the only cause of death." "This is one piece that we have measured, there are many, many things that contribute to aging in individuals," Heidinger said. 9) in the journal Proceedings of the National Academy of Sciences. The loss of telomeres may ultimately contribute to death by causing body systems to fail, but which systems and when are likely to vary, resulting in different causes of death for different individuals, they write in a study published on Monday (Jan. Many other factors - damage elsewhere in the DNA, accumulating damage to biologically important molecules, reduced capacity to replace lost cells, and so on - are also implicated in aging. The researchers did not track the birds' eventual cause of death, but they know these did not include accidents, predators, starvation or infection. Telomere length measured at other times during the birds' lives did not have the same strong correlation to life span as the initial measurement. In order to complete the study, the birds were allowed to live out their natural lives, with blood samples taken when they were 25 days old, then 1 year old, and periodically afterward. Telomere length can vary greatly between individuals of the same age genetic inheritance appears to play some role, as do environmental factors, which are linked to oxidative stress it occurs when the body produces more reactive oxygen molecules than it can neutralize. Telomeres prevent the uncontrolled cell division characteristic of cancer, but cells with short telomeres can become cancerous by evading this limit, according to Pat Monaghan, the senior researcher and a professor at the University of Glasgow. Previous studies have suggested this process contributes to the deterioration associated with aging. So, every time the chromosomes are copied the telomere shrinks a little.Įventually, with age, the telomeres shorten to a point where the cell can no longer divide, and most normal cells cease to function. They naturally become shorter over time, because when the cell's machinery copies its chromosomes it misses the very tip of the telomere. Telomeres serve as markers for the ends of the chromosomes. Each of our cells contains chromosomes, capped by telomeres, and when our cells divide - a necessary part of growth and the maintenance of our bodies - these chromosomes must be duplicated. And while it seems reasonable that telomere length early on could predict life span in humans, too, it's not yet certain, since no similar study has been completed in humans, according to Heidinger.Ĭhromosomes are threadlike strands of protein and DNA (deoxyribonucleic acid), which contain the instructions to make a living thing. For relatively long-lived vertebrates, such as zebra finches and humans, aging and telomere loss appear to go hand-in-hand.
