Scales and stones, Part 2

We were working farther north in Sonoma County this morning.  On our walk back, we had some nice views of the local lizards and stones.  Here are a few of my favorites:

ADDENDUM (26 April 2019): Thanks to Lotsoflux's comment/question, I recalled another time when we observed Black Oystercatchers eating sea urchins.  Here's a photo showing examples of oystercatcher prey items at a site in Mendocino County in May 2013 (clockwise from top left) Mossy Chiton (Mopalia muscosa), Purple Sea Urchin (Strongylocentrotus purpuratus), limpet (likely a Shield Limpet, Lottia pelta), and California Mussel (Mytilus californianus).  [I positioned them for the photo.]
