Warm Weather Friends
By Cori Carlson, Administrative Assistant
In Spring, we all expect to see lots of baby squirrels and baby birds. But here in Southern California, as the weather warms up, we also start seeing more activity from our local lizards. One of the most common species found in the Santa Monica Mountains is the Western Fence Lizard, appropriately named because they are often spotted running along fences. California Wildlife Center (CWC) admitted seven of these small reptiles last year. The majority of these patients were injured by a house cat or wild predators. In the past, we have also admitted lizards who were unintended victims of glue traps. While these lizards are being rehabilitated at CWC, our technicians provide a diet of mealworms, flies, fruit flies and crickets similar to what they eat in the wild.
Growing up to 8.4 inches in length, Western Fence Lizards are covered with gray, tan and brown scales. This camouflage, though, hides a secret which earned them the nickname “blue-bellies.” Adult males have bright blue patches on their stomach and neck which makes them stand out to females and helps attract mates. You will often see male Western Fence Lizards doing push-ups to show off their handsome colors and warn away other males during mating season.
Cold-blooded, these lizards regulate their body temperature by moving in and out of the sun. This is why we see them out during the day often sunning themselves on paths, rocks, and fences. Unfortunately sunbathing also can make them an easy target. An encounter with a domestic pet or natural predator can result in lacerations or puncture wounds. To help protect themselves from these injuries, the small lizards have fast reflexes (maybe because all of those push-ups) and are able to drop their tail to escape predators and regrow it within 3-5 weeks.
Western Fence Lizards are more than just good food for our local predators; they are directly beneficial to humans by lowering the occurrence of Lyme Disease. When infected ticks feed on these reptiles, a protein in their blood kills the bacteria that causes Lyme disease, cleansing the tick of the disease-causing microbes.
CWC has already received our first two Western Fence Lizards of the year. As we head into one of our busiest seasons, we are ready to admit many more. To keep our reptile friends healthy (and out there contributing to the health of humans), keep cats inside and consider alternatives to pesticides or glue traps in your garden.
I really enjoyed this article! The part about Lyme disease was fascinating.
Thank you for your kind words, DJ!
