Feb 13. 3 mi. EST Del Valle, 400 ft., Travis Co., Texas oblivious of singing bird. I took this bird (725), wounding it in such a way that it was voiceless. No response from any other bird and I continued to sing. Detached film and took him (726). Mate relationship is assumed on the basis of advanced state of ovary of 725 and fact that she was taken about 20 feet from song posts of 726. I heard no other tidbits in the area W of the pasture although Dr Miller took me across the draw on the slope W of one where 726 sang. Density in ridge-top oak-juniper seems to be sparse.
