Greene, H. 1989 June 9 (continued) Driving out from the ranch, we stopped to catch a large adult ♂ Holbrookia maculata < 100 m from the junction w/ Hwy 80. It was sunning on a rock ≈100m, on open red soil near scattered grasses -- as we approach to noose the lizard it ran ≈1m and frozen w/ its head in a grass clump. It struggled and gaped to bite when handled. Walked around to look for others, but saw only Cnemidophorus uniparens. Nest pulled in at a ranch gate a few miles further SW -- just over the hill from the long sweeping S-curve where I caught Sistrurus last year. Walked up to an abandoned cinder mine, from which I took photos SW, E, and NE of the valley. Saw two small adult (bright green) Crotaphytus collaris, one under tin and the other under an old tire. Tony saw a thraurus. There is a raven nest on some sort of rusty, probably mine equipment, causing us to speculate that one could have poached raven eggs after a lightning storm. There is at least one barn owl nest site in a box in the hill at the mine, with a pile of pellets and rodent bones below it. The soil here is a rich red-brown, about like the coat of some Herefords or perhaps a Santa Gertrudis. It is very dry now, the grass light yellow-brown.
