Saving Our Wildlife
February, 2014

Call it the Circle of Life or Survival of the Fittest-wild animals in the wilderness die of starvation, diseases, and predators. This is a natural part of life and most wildlife rehabilitators take a hands-off approach and let nature take its course. For instance, at Ano Nuevo I saw baby elephant seals lying on the beach in extreme distress. The ranger explained that marine mammal organizations don't rescue these animals, as heartbreaking as the situation is. Instead, their mission is to rescue those creatures harmed due to human causes, such as caught in fishing nets and choked by plastic six-pack rings.

About 90% of the animals brought to wildlife rehabilitators are injured, sick, or orphaned due to human-caused circumstances, whether intentional or inadvertent. Oil spills, habitat loss, and forest fires caused by campfires are responsible for devastating harm to wildlife, requiring the intervention of specialized rescuers. However, with just a little caution and foresight, ordinary people can do much to prevent accidental deaths and injuries to localwildlife. It can be as simple as putting decals on your windows to prevent birds from flying into them. By increasing public awareness, wildlife rehabilitators hope to encourage people to alter habits and thought processes, thereby reducing the need for rehabilitation.

Driving alertly and within the speed limits, especially at night, can save the lives of the deer, opossums, raccoons, and skunks that are too often road-kill. Car collision injuries are the most common seen by wildlife rehabilitators, including a red-tailed hawk just admitted to WERC that was side-swiped and suffered a concussion. 

Glue traps and poisons are indiscriminate killers and often end up being responsible for the death of wild birds, mammals, and reptiles that die from struggling to free themselves or from starvation when they can't. This screech owl got stuck in glue while hunting a trapped mouse. The skin ripped off its foot and the wounds became gangrenous. Sadly, it was necessary to euthanize the bird. 

Anti-coagulant rodent poisons don't kill the rodents immediately. They eat the bait, run out into the fields, and entice predators such as owls, hawks, bobcats, foxes, coyotes, and even neighborhood cats and dogs. These animals then digest the poison too. Tragically, that's not the end of it-carrion-eating scavengers such as opossums and turkey vultures may eat the dead animals and die themselves from third-hand poisoning. There is even fourth-hand poisoning such as the litter of baby opossums that all died after they had nursed from their poisoned mother. It's ironic that those predators affected by secondary poisoning can do so much to control the rodent problem. A more humane (to wildlife) method of rodent control is the old-fashioned snap trap.

While outdoor cats may control the rodent population in barns and fields, they do much more damage to the bird population. Free-roaming pets kill millions of wild animals every day. A cat's saliva can contain toxins and even a scratch can be deadly to the animal. Cat-bites are the second most common reason for admission to WERC, including a mourning dove currently in rehabilitation with a neck wound and missing feathers. 

Every spring, wildlife rehabilitators across the nation receive countless orphaned and injured baby birds and squirrels because they've lost their nests due to yard maintenance. Even trimming trees around the nests can be damaging because the nest's covering may be lost, exposing the babies to predators and hot sun, wind, and rain. It's against state and federal laws to remove, destroy, or disturb most nesting birds and squirrels, and their nests, eggs, and young. And remember to check the grass before you begin mowing, roto-tilling, or weed-whacking-animals such as rabbits and some birds nest and hide their young in the tall weeds.

The saddest of all cases in wildlife rehabilitation are those animals that are deliberately killed or maimed. That was the case of the crow that I found struggling on my driveway recently. A bb had pierced a hole through its wing, fracturing the bone, and causing the wound to become infected. The intelligent bird was euthanized to put it out of its agony. WERC has seen its share of animals that were gunned down: A mother bobcat dead from a gunshot wound. Next to her were her two kittens, one already dead of starvation; a turkey vulture shot out of a tree on Christmas eve; a great horned owl whose wing was riddled with buckshot causing permanent damage; a red-tailed hawk nicknamed Hope with at least 6 pellets in her wings, neck, and beak; and a mother opossum carrying babies. The surviving bobcat was rescued just in time and was released after 7 months; the vulture's wound was much worse than first suspected and he was euthanized; the hawk required long-term care but was eventually released; the owl could never be released but he was fortunate to become an educational animal at Happy Hollow Zoo; and although the mother opossum died, her joeys survived.

A WERC staff member once stopped several teens shooting birds out of trees at a local school because their cat was "too lazy to hunt". It's critical for parents to supervise and teach their children responsibility and correct usage of pellet and bb guns, whether used for target shooting or for legal hunting. 

Better to "shoot" with a camera. Your photo of a deer or egret will last longer than a memory. Let the wild critters live long and prosper!
