It was a snakey day in the Park today! Greg Nemes kicked off the Junior Ranger program with a session on snakes. We didn’t see any live specimens that hour, but he found a toad to show the kids.
A short time later, Ranger Allison was removing a rattler from the bridge over Stokes Creek, and throughout the afternoon at the VC, lots of visitors came in to report rattlesnake sightings. (Also seen that day: a bobcat and a mountain lion!)
Spotted this handsome striped reptile out on the trail. The California kingsnake (Lampropeltis californiae) is endemic to the western United States and northern Mexico, and is found in a variety of habitats, including woodland chaparral, grassland, deserts, marshes, and even suburban areas. It is non-venomous, and kills its prey by constriction.
Wild California kingsnakes are typically encountered at a length of 2.5-3.5 feet (76 – 107cm), though they can grow larger. This one was smaller, maybe 18 inches / 45cm long.
During the rains we had a surprise visitor, a blind snake! It’s our first time seeing this earthworm-looking reptile. Rena humilis is found in the southwestern United States and northern Mexico. It lives underground, sometimes as deep as 20 metres (66 ft). Having no need for vision, its eyes are vestigial, just two light-detecting black spots. The skull is thick to permit burrowing.
Its diet is made up mostly of insects and their larvae and eggs. It is found in deserts and scrub where the soil is loose enough to work, so I’m not sure what it was doing in our living room! I moved it outside, and noticed that my hands smelled like mushrooms afterwards. Very earthy.
This was the second little snake in our empty pool before Hurricane Hilary blew into town. Two new-to-us reptiles in one night! Very cool.
Fun visit last night from a tiny, rarely-seen snake! Very exciting.
Yesterday was our annual brush-clearing day. Sadly, the labourers did not share our respect for rattlesnakes.
I asked my herpetologist buddy about this pulsing behaviour, and he said he had observed it in several species, including gopher snakes. No good theory on why they do it. He added that there’s a ton we don’t know about snake behaviour.
After stopping in a shady spot to paint a profusion of Sticky Monkey-flowers, I came around a corner of the trail and surprised a California Striped Racer. It tried to climb the trunk of an oak but didn’t get purchase and fell to the ground! I have never seen a snake ‘fail’ like that, and we were both momentarily stunned. Faster than I could whip out my phone, it recovered and raced off through the undergrowth at its signature speed. Sorry for disturbing you, little buddy!
After my hike in Solstice Canyon, I had a little sit down on a rock by the creek. This fella saw me before I saw it, and froze while I took photos and did a rough sketch (completed at home). Then we both went on our merry ways.
