Feb 9. 2 1/2 mi. ESE Del Valle for 100 yards or so and heard a soft teet. I located a tomnorse 30 feet upslope and fired at it with a .38- bird flew N and so did mate. I followed cautiously and heard another such note about 30 ft farther N, tomnorse on small branch in .38 range so I took it, (?,704). Then I waited fully 5 minutes, listening before I started looking for the mate. I whistled heur -- and obtained no response. Finally, walking along higher on the bank I saw the mate lying dead about 15 ft upslope from ?04. This bird, 703 or was a near-bicolor while the mate had a pale frontal patch suggestive of the Victoria County birds. The sketch map shows approx. relative positions of the birds. I am certain that all the birds along the creek from (2) to (3) were taken into account. (3) mesquite prickly pear steep bluff (4) (5) Onion Creek (6) (2) grain field (1) to Colorado River (1) - pair, 8:40 a.m. (2) - 699-700 taken ?9:15 (3) - unmated ?, 705 taken 10:30 (4) - point where 705 first sang (5) 701-702-10:40-11:10 (6) 703-704 taken 11:50
