22 July 22 July Up about 7:15 am. Skies completely overcast as it was yesterday. Walked along the river where we saw the turtles & then checked out a box canyon feeding into the river valley. Saw nothing but a few Urosaurus ornatus. Went over to the west side of the Rio Yaqui just south of Norillo, Sonora so that Jim could check the gopher situation and compare it to the east side. He got Thamnophis unbrivius on the west side just as he had gotten it on the east side. I did a lot of checking along the river and finally saw or caught the following. 406 Sceloporus clarki: Several seen on the trees and this one specimen taken off the rocks. 407-417 Urosaurus ornatus: many seen. very common. The lizards seem more wary & harder to catch on both this side of the Rio Yaqui & the other than at other place. Got the following series off the wooden railing of a corral. Field No. Sex. SVL TL Throat color. 407 F 48 46 orange 408 F 49 - faint orange 409 F 50 84 faint orange 410 F 49 71 yellow 411 F 54 87 orange 412 F 51 66 faint orange 413 F 51 79 faint orange 414 M 51 53 yellow
