Parus Apr. 20. Mayhaw Creek, 15 mi. W Bastrop, Bastrop Co., Texas Failing to find the supposed ? in the elm grove, worked on crossing the streamcourse w the farm bldgs. At 10:55 I heard a bitmoresinging peter -- from magnite- scrubby elm up a slight rise. At 10:59 I flushed 2 doves with the usual whirring call. The bitmorse ceased his song and gave a rather anxious-sounding note geep, then, high-pitched. It was geep-geep, second note lower pitched, then -- -- 2 calls presently, then just single notes of rather plaintive quality. This continued until 11:04. Three minutes later, this bird commenced to sing peter -- from scrub to N and I was able to take it (#58) at 11:10. I proceeded N toward pipeline - SUN BREAKING through, WIND FROM SOUTH, to 10mph in gusts. I encountered a bird I thought was a thrush in the S of stumps where I first saw this bird on Apr 15. I had no satisfactory view but bird gave a call deh deh, then a very strange call (the same bird I believe) whuh whuh whuh huh hō hō hō hō hō Hoarse Like Sreech out in rhythm but of quality of setting her Bird called from N pipeline but I lost it at 11:25. No song except Minus by 11:38 as I wrote note I left area at 11:45
