Murray 1948 55 Journal May 9 San Jose de Comondu, 700 ft., Baja California Today I have seen a verdin, canyon wren and a costa hummingbird which has a nest in a large tree behind the house. The nest is located on an outer branch, about 4 ft. high and poorly concealed. Saw a Streptosaurus mediusi and Cnemidophorus t. rubidus, both among the smaller rocks on the hillside. This hillside is lava talus in great quantity, with pitahaya, pitahaya dulce, cardon, lumboi, ocotillo matorra and a number of other brush forms growing to a varying degree. In some places there are quite large boulders. On this terrain behind our house to the south, put out 50 live traps about 50 ft apart. Tonight we all went out to shoot bats in open fields among the palms. The others got Pipistrellus and Eptesicusfuscus. The pipistrelles were moderately common, began flying before dusk fell and stopped earlier than the others. Saw as many as 13 turkey vultures circling both high and low overhead. In the afternoon Gust shot what I am sure is Streptosaurus repens on a rock.
