J.B. Ruth 1969 Journal May 4 Laguna Dam 20 mi. N Yuma Arizona got up about 5:15 AM got to dam 20 miles from Yuma Arizona about 5:30. We drove out across to dam and turned left and drove along the island maybe 360 yards long by 80 yards wide. By 7:00AM we had gotten 5 Leptotyphlops humilis. I found all 5 under rocks on the surface in low places in clearings of tamarisk groves near the end of the island. Refer to R.C. Stebbins species account for more detailed account of this species. It is an overcast day with a slight breeze, On Laguna dam at 7:45 we see Rough winged swallows (few) and Bank Swallows flying low over the water coming out the spillway. Earlier at 5:30AM we saw many egrets standing on rocks just below the spillway where fishermen now stand. Yellow Parrots are seen, Several Black Phoebes
