Western Whiptails were active along the trail from O'Shaughnessy Dam to Wapama Falls from 9:30 to 11:45AM. These lizards are more commonly observed in open habitat, running from bush to bush.

This lizard is most often heard before it is seen. They are excellent leaf litter "swimmers." In quiet moments, listen for feint rustling in the leaf litter (most commonly oak).  They will periodically peek their heads out for a look on the surface. This individual was observed close to the picnic tables near the rest rooms at Hetch Hetchy. A blue-tailed juvenile was observed cruising in the leaf litter near Hodgdon Meadow employee housing.

    Mar 30 2015 I spent many summers near Yosemite in my youth. Today I brought my kids here to "see the beauty of nature". While stopped at Tunnel View we saw a Weatern Skink, a "swift" blue-belly, a beautiful golden eagle, and later at the Mariposa Grove we saw a weasel! The kids were so happy and excited to see the nature of the Yosemite area.
