K Dixon 1952 Parus atricristatus Feb/19 17 mi. S Washburn, 3400 ft., Armstrong Co, Texas. I proceeded downstream but heard no more titmice by the time I reached a larger stream flowing in from the NW. This larger canyon was much broader, those being a terrace above the stream often 100 yds either side. wide on. Junipers grew dense on this bench and there were elms and mesquites (especially the latter) scattered throughout. Cottonwoods in some numbers lined the edge of the stream forming broken rows. I worked upstream about 1/4 mile after 10:00 and was accosted by a titmouse as I crossed the stream. This bird was in the cottonwoods and I located it foraging on trunk bark. I fired at it with a .38 and it flew. My second try was with a 410 at long range - bird flew, presumably uninjured. I crossed the stream again and worked S toward that wall of this broad canyon. I worked through junipers part way up the slope but heard no titmice and stirred up no response by whistling. I returned to the confluence of the two streams at 12:10 and heard a titmouse call there. I followed the inter- mittent vocality trying to locate caller. Bird would remain quiet for extended periods, then call at some distance from previous locale. I finally saw the bird in a cottonwood and fired at it with a 1/2 load - it flew N - then I heard accost to NW - same bird. This caller led me a merry chase up N bank, across ridges.
