K Dixer 1951 Parus bicolor Apr. 18 8 mi. E, 3 1/2 mi. S Del Valle, Travis Co., in Bastrop Co., Texas Complete overcast; light breeze from E. I reached this area, visited Apr. 8 and 15 by driving E from Del Valle 7.5 miles, turning S on gravel road 3.5 mile to first intersection, than driving E 0.5 mile. I reached the area at 8:20 and proceeded to the nest which lies by compass NNE of the first telephone pole E of the pond. At 8:26 a titmouse flew S toward the road as I approached the nest. I heard song from that quarter subsequently. At 8:33 a titmouse approached the meagrite from SW and perky within a foot of grand prominent limb - 3 birds in succession, then entered nest front with fecal sac (food in bill green) - simultaneously I heard song of 2 titmice peta peta and pee-pee-pee faintly to E. I walked S into property S of road at 8:40 WIND STRONGER FROM SE, to 10-12 mph. I crossed the pipeline & telephone wire, both of which extend E-W and on into mesquite with a few scrubby elms. I heard song exchange of two titmice lewa lewa of S to S (N bird silenced as I approached) I followed S bird 8:45 - 9:00 but had only one glimpse but impression of bluishish on frontal area. Song answered by birds to S and W, the latter perhaps the bleached & seen Apr. 15. Silence at 9:00 Bird sang again at 9:06 and I located it in dead elm & watched it as it moved actively through adjacent mesquite & elms. Song from N briefly at 9:10. Silence at 9:15 - song resumed at 9:17 with song from SW and NW also. Bird silent again at 9:21 after intermittent song.
