San Felipe, S.L. Lower Calif. Mexico. March 26, 1926. rattlesnakes while I was walking between bushes on the open desert. They were & wound around one another in a round heap and did not rattle even when I had stepped within a foot of them before I had saw them. They did not rattle or unwound until Lamb had come up and made a motion at them. Both were small but had 7-8 rattles. Perhaps by coincidence their rattles went together. We also killed a jack Rabbit also, one a male and the other a pregnant female large with young. We saw three Great Blue Herons flying about a half a mile inland and regularly on some ironwood trees. Upon upon- ening their nests in some ironwood trees we found them empty. #I shot a pair of great catchers from a mesquite bush right next to camp in the afternoon. Caught 2 & spermophiles at the traps in the afternoon. Saw two large lizards in the bushes during the noon time.
