KDixon 1949 Paris wallweberi Apr 24 Sawmill 27 mi NE Globe, 5600 ft. Gila Co., Ariz. flew to a nearby scrubby oak. This call is identical to that given by a Plain Titmouse which is frightened. This bird then picked something from the foliage of the blue oak with yellowing leaves and, holding it between his feet, hammered at it with 4-5 blows then flew to another perch half a foot higher. As I fired the bird moved, then fell to the ground. When I started to pick it up, it flew off to the west and I never found it. Head was bloody on one side so survival is doubtful. (See NW ranger station) Apr 25 About 8:15 AM I heard a singing a song similar to the Wren's while his mate (presumably) answered with a rickadee note. After a few minutes the birds were silent and I heard them no more during the 15 minutes that I walked over this oak-juniper S-facing slope. An hour later I heard the singing from the same slope but there was no song from a rival male. I have never heard such in the case of 4 or 5 males I have heard here. Pairs must be distributed thinly in locally favorable habitat. The Bridled Titmouse I have seen have always used the oaks. I have seen no Plain Titmouse here although Russell collected one and saw another about 75 yards from a pair of Bridled Titmice in oak-juniper woodland. In this particular habitat the Bridled Titmouse appears to be present in greater numbers for reasons which need further study.
