K Dixon 1952 Parus bicolor Feb 6. 15 mi W Bastrop, 600 ft, Bastrop Co. Texas CLEAR; WIND FROM N, stray but shifted to W by 9:00 and then back to E by 9:30. I reached the brook near the dam at 8:23 and processed partway downstream to road, then S'd into elm grove. I worked back and forth, and worked into small (middle) elm grove. Flock of chickadees and kinglets here at 8:45 -- Field Sparrows also. I moved into W-most elm patch and scanned there for 20 min. No sign of a titmouse. [As I consider now, the first I taken yesterday at the E edge of that grove was the resident (#678). The lone bird I find at about 10:40 was his mate in all probability. The status of the other J(679) is problematical.] I worked in elms to E after 9:30 CLOUDING IN; wind from north, velocity variable. 9:50 -- as I came upon bird flock on N bank of brook below dam, I heard vet vet vet of titmice. The silent member of the pair seemed to be leading the way, keeping with the tinglets and warblers. I circled to S once, then again as scold heard from one bird and other not seen. The silent bird was still leading the way and I went ahead too far (into N bank area W downed log in meadow [scene of dispute Feb 3]). I worked back at 10:00 and saw bird believed to be the J in mesquite N of brook and SE of elm where I last seen. He called vet-vet-vet and seet-seet (coupled, nearly melodic) seee-chejay once, a sputtery peeta (one phrase only) then the hissing phleet-phleet.
