There were many of these... Foliage reminded me of Fremontodendron but they were no more than knee high.
Found this guy at the bottom of a moist compost pile. My gloved finger shows in the second photo. His tail was apparently bitten off and healed. Remarkable he was there since the garden is surrounded by pavement and buildings.
I came upon this pair, the snake had his jaws clamped around the frog. As I took photos, the snake opened it's mouth suddenly, but neither moved for several seconds. As I took more pictures, the snake finally took off and the frog hopped away. I wasn't sure if I was happy for the escaped frog or sad for the snake without lunch.
Daily in my back yard, one or two of these pass through on the same path, but rarely land, despite my native garden. What are they looking for?
