Chaparral/coast sage scrub animals

June 2016 Melrose coyote

Coyotes are the top predators in our coastal sage brush habitats.  And they don’t necessarily stay put.  Being highly adaptive, they will go where the food is which could be your backyard.  Increasingly, people are putting themselves in conflict with coyotes.  But there are things  you can do.  See the flyer from the California Dept. of Fish and Game:  Keep Me Wild 2013

Kangaroo rats aren’t actually rats but mammals capable of extracting all the water they need from their environment.  They drag their tails and, generally, hop on their hind feet.  You should be able to see their hind feet and tail drag in the photo:

Trapdoor spiders

At our April 12th hike, we saw lots of trapdoor spider holes.  Here’s just one:

These spiders (superfamily Ctenizoidea, family Ctenizidae) are medium-sized mygalomorph spiders that construct burrows with a cork-like trapdoor made of soil, vegetation and silk. Some similar species are also called trapdoor spiders, such as the Liphistiidae, Barychelidae, Cyrtaucheniidae and some Idiopidae and Nemesiidae.

Wood rats are an indicator species telling us that the habitat is reasonably healthy.  In the Calavera Preserve there are many wood rat nests most commonly found under laurel sumac trees.

This pretty caterpillar turns into a rather drab moth.  It likes to feed on our native deer weed among other plants.  We saw it early in March, 2013.
