After 54 Years, My First Western Skink

This morning at Oaks Bottom Wildlife Refuge in Portland, I saw something I’d never seen before.

A Western Skink, sunning itself on the stone steps along the trail. Brown body with clean longitudinal stripes, an iridescent blue sheen across the scales catching the morning light, a long tail flicking against the rock.

I’ve walked these steps for years. I’ve never seen one. This was my first.

I tried to move it off the step so it wouldn’t get stepped on by other visitors. It slipped into a crack in the rocks faster than I could blink. Then it was gone.

I almost didn’t recognize it as a skink. At first I thought it might be a garter snake — the long body, the longitudinal stripes, the way it moved. Then I noticed the legs. Five-toed front feet, small but visible. Reptile, not snake. Then I considered alligator lizard, which also lives here. But the scales were too smooth and shiny, the body too slender, and the iridescent blue sheen was the giveaway. Western Skink (Plestiodon skiltonianus). Confirmed.

What Western Skinks are

Western Skinks live across the Pacific Northwest from southern British Columbia down through California. They prefer sunny rocky areas with cover — exactly the kind of stone-step habitat at Oaks Bottom.

A few features that make them special:

• Iridescent blue scales, especially on the tail in juveniles. Adults retain a subtle blue sheen across the body in good light.
• Tail autonomy — they can drop their tail when grabbed, then regrow it. The tail sometimes wriggles separately to distract predators.
• Egg-laying with maternal care — unusual for lizards. Females guard their clutches of 2-6 eggs until they hatch.
• Lifespan of 5-10 years in the wild, longer in captivity.
• Diet of insects, spiders, and small invertebrates — they’re part of the natural pest control at Oaks Bottom.

Why this matters to me

The lizard had been there before. Maybe the same individual I almost stepped on this morning has been using that exact rock crack as its home for years. Maybe its parents and grandparents lived there. The wetland is full of life I haven’t trained my eyes to see yet.

I think this is one of the quiet rewards of returning to the same place over years instead of always seeking new places. The first ten times you walk a trail, you see the obvious things — the herons, the eagles, the wood ducks. The hundredth time, you start seeing the smaller things. The skink on the step. The tree frog under the leaf. The mink along the bank. Each one was always there. Your attention wasn’t.

This is also the soil microbiome practice from my last post applied to a different sense. Hands in dirt deliver M. vaccae through smell. Eyes on the same trail year after year deliver new species through pattern recognition.

Both are free. Both compound with consistency. Both reward the slow accumulation of attention.

A note for fellow walkers

If you walk the stone steps near the entrance to Oaks Bottom on a sunny morning between now and July, watch for Western Skinks. They sun-bask between about 8am and 11am when the rocks are warm but the air is still cool. They retreat into cracks instantly when you approach.

Most people walk past them. Once you’ve spotted one, you’ll never miss them again.

I’m 54 years old. This was my first Western Skink. The wetland is still teaching me what it contains.
