K Dixon 1949 Parus wolweberi 2. Apr 23 Sawmill, 27 mi. NE Globe, 5600 ft., Yola Co., Ariz. After 10:00 AM I followed a pair of birds on the ridge top in juniper and oak not more than 12 ft high, scrubby yellow pines scattered. I saw the female hanging from bottom of a cavity peering in, then out then in again. I shot at her & missed. The male simultaneously was singing from a position 10 yards to NW. The pair foraged in an oak 10 yards north I prospect position following which I lost them. The most frequently used note was a soft somewhat plaintive see see dee and occasionally a soft pit, notes which I take to be contact or location notes, practically indistinguish- able from those of the Plain Titmouse. These birds flew from oak to oak. Perhaps half an hour later I was calling to a Slate Warbler downstate a few yards to the west. A Bewick Wren was answering and 2 Brittled Titmice appeared in a young pine beside the wren giving a call see see see dee (high pitched) and one individual gave a chattering note which I cannot transcribe. I collected one individual (#349 ) and the other remained in the vicinity calling occasionally but I was unable to take it. My impression was that the vocabulary is more like that of the Chickadees with none of the harshness nor the strength of the calls of the Plain Titmouse. Note with collection of #349. One of the titmice gave call see see see dee apparently antagonistic toward Bewick Wren in print with them. In general this species seems less pragmatic than P. inornatus.
