K Dixon 1951 Parus bicolor II. Mch 14, 9 mi NW Bryan in Robertson Co. Texas. The titmouse was singing from trees at the edge of the pasture at 10:30. It moved S rapidly along this 'edge'. At 10:40 it was still singing at the edge of a clearing (asterisk on map) The bird continued singing peta peta peta; its nest was erect but little chestnut showed on its flanks (covered by wings.) The bird appeared to be alone. After 10:40 the bird sang more rapidly. At 10:44 it flew E to the other edge of the clearing and continued singing there. I left at that time. I worked W into deep woods. Cattle grazing there. SUNNY, CALM. The woods here consisted chiefly of post oak, in some cases draped with Spanish moss. Some of the trees bore catkins. Undershrubs included hawthorn and 2 species of Ilex (both evergreen) The latter according to John Wood inside in areas of disturbance such as grazing. He thought that the climax consists of post oak woodland with grass covering the ground beneath and the undershrubs scattered. At 11:07 I heard a song "riddle-ye riddle-ye riddle-ye riddle-ye" given several times. I saw a pair of Cardinals and a titmouse in the area after song had ceased. (Source of song??) The pair of titmice foraged on twig bark but chiefly by hanging upside down to pick
