Earlier this spring I realized we had accidentally created some nice habitat for western skinks, an entertaining, exotic looking little guy with a beautiful blue tail. There was a lot of driveway gravel and random small rocks piled at the base of our crumbly basalt bank. I saw one weaving in and out of the rocks, and thought myself lucky to have a long look. Then I realized there was a second one, and they were playing hide and seek and chasing each other around, oblivious to me!! Ahh, spring.
According to Reptiles of the Northwest blue color in the tail is temporary – bright on juveniles, fading to grey or grey-blue in adults. I always see the blue tail disappearing in a flash. I have no idea how Alan St. John, author of the field guide, is able to capture them. But capture he does, and writes lovingly and entertainingly of skinks and other reptiles. A great read.
Weeks later I was gardening and flushed one out of the undergrowth. It immediately dashed for a rodent hole, but poked it’s head right back out again. We had a stare down, but the skink had the better skills, because if I looked away for one second, it would advance a centimeter and then freeze. I could not see it move, but there it was, inching forward. At the right moment it disappeared into the rockpile.
These guys are fast – like other lizards they can dash so fast that they can’t be caught, but are unable to keep up the pace, so their strategy is to dash, freeze, dash, and if all else fails sacrifice their tails, which can regrow if they are detached. The detached tail even wiggles to distract the predator while its owner gets away.
You can create habitat that snakes and other reptiles use by hollowing out a protected and dry place in a sunny area and covering it with stones and a little woody material. They will find the spaces beneath and this hibernaculum will be a refuge in the winter too for slug-eating garter snakes and others.
