How Long Do Wild Animals Live?

Meet Our Geriatric Downy

We often see a geriatric Downy woodpecker at Winding Pathways. He’s at least five and a half years old. More likely six or seven.

How do we know? Well, back in the spring of 2021 Dr. Neil Bernstein brought a class of college students to our backyard, strung a nearly invisible mist net and soon started catching and banding birds. One was a male downy woodpecker. Neil gently attached a tiny aluminum band to the bird’s right leg and released him.

Spotting the Band

For several years we watched the bird eat suet from a feeder near our back deck.  When the light’s just right and the bird’s right leg is visible, we can see the band. Our last sighting was in late 2025. So, he’s been banded four and a half years, and was likely at least a year old when banded.

Could it be a younger woodpecker banded by Neil or someone else miles from our yard?  “Not likely. Downy woodpeckers are homebodies. He probably has lived right here in your yard continuously since he was banded,” Neil recently told us.

We haven’t been able to restretch a mist net and recapture the bird. If we could read the tiny numbers on the band we could confirm whether or not that it’s the same bird. It likely is.

Wildlife Longevity

Most wild animals live a shockingly short life. It wouldn’t be a good idea to sell a life insurance policy on nearly any wild animal. They die young. Wild turkeys live a few years. A cottontail rabbit is not likely to live to its first birthday. The same for most songbirds and mammals. A whitetail deer could live for eight or ten years but few reach their second or third birthday. Usually, wild animals succumb to a predator, die in a storm or are hit by a car. Many birds meet unfortunate deaths when they crash into windows or overhead wires.

Reproduction is Important

Since few animals survive long enough to reproduce, their species continues because those that do make it to reproductive age have many babies. That’s especially true with fish. A largemouth bass or bluegill, for example, could live for upwards of ten years.  They lay thousands or even tens of thousands of eggs, but nearly all die soon. Of the lucky few that emerge as young fish many are gobbled up by bigger ones. Only a few reach old age.

Longevity Champions

Reptiles may be the longevity champions, with turtles and tortoises sometimes living for decades, or even a century. A box turtle might live 35 years in the wild and much longer in captivity. But these long-lived animals lay few eggs and their babies mostly die when young. If they make it to young adulthood, they stand good odds to enjoy a long life.

Back To Our Downy Woodpecker

Our downy woodpecker has lived a charmed life. He’s not been snatched by a Cooper’s hawk, frozen in a blizzard, or died by an accident or sickness. The oldest known Downy lived for 11 years and 11 months. Most are lucky to live two years. Maybe ours will set a longevity record.

Helping Wildlife

His life may have been helped by having plenty of dead trees near our yard, the result of a massive windstorm five years ago. These old trees are filled with cavities that offer safe places to hide, escape storms, and raise a brood. Our Downy comes for regular helpings of suet at our feeder. That may help him.

We use the word “he” because male Downys have a blotch of red on the back of the head, making it easy to determine gender. Many Downy woodpeckers come to our feeder. We always look carefully to see if it’s our banded male.
