LL Wolf 1964 Aimophila aestivalis June 19 1 mi S. Baykin Springs, Jasper Co, Texas Head 10-20° below horizontal & looked in direction of nest. Back to above horizontal - repeated several times + then dropped to ground below pine. Can hear occasional chips as could when in small pine. 0953 - up into small pine. ♀ over to smaller pine tofts about 10-15 feet. Then sat on live branch 8'' above ground among needles at end tuft. Looked at ground + generally maintained horizontal axis. 0917- ♂ flew to SW 75-100 yards + sang several times - followed there by ♀, 0921- ♂ still singing. - appears they noticed some disturbance likely caused by me looking for nest. 0923- ♂ quiet. 0951- Although not quite simultaneously heard ♂♂ sing 100 ±(?) yards to SE followed by ♂ from SW mere where last saw ♂ I am watching. When ♂ (#1-mine) stopped then ♂ #2 started again. Enough time between. Probably to get back & forth, but doesn't seem likely. 0937- ♂ #1 began singing 0945. ♂ #1 still singing, but sounds as if he moved slightly to N. Now fairly sure that ♂ #2 is due to ventriloquistic effect of song of ♂ #1. 0950 - ♂ #1 silent:
