S Adel, Lake Co., Oregon May 26, 1937 - On this the second day of collecting, observation and collecting was done farther from the immediate mouth of the canyon. Two of us went up along the east ridge of the canyon to something of a sagebrush covered mesa. Our third member went fairly high up the west side of the canyon - high enough to get into numerous small junipers. These extensions of habitats studied were of interest in com- parison to the lower habitats already studied. On the sagebrush mesa (low sagebrush of predominated one species [Lueff, '42]) Brewer Sparrows were decidedly abundant. Dr. Miller collected several Verper Sparrows and a Sage Sparrow - neither of which have been seen lower down, although the couple hundred feet of higher altitude give rise to little difference in vegetation. Some observations were made in regions of red or dark lava boulders. Rock Wrens were the most abundant and almost the only bird here associated. However the Rock Wrens seem pale to me and their association with dark lava might tend to disprove their possible protect- ive coloration. A single lizard was seen (will be collected, if possible, in future) on the dark red rocks. It was definitely red, or reddish coloration. This protective coloration,
