H.W.04 1964 Amophila aestivalis June 18 1 mi S Boykin Springs, Jasper Co, Texas 60 deg angle. 0733 - bird (?) which had disappeared into shrubs 5 min earlier flew up into small pine (15 feet tall) onto lowest dead limb (4 1/2 feet up). Gave loud "chink" just before landing. Stayed momentarily on this perch + then changed perches 4 times moving higher + into branches of pine 2 feet away. Then flew 70 yards low where sat on dead pine limb 15 feet above ground. Sang once + then began to preen @ 0740 - preened essentially continuously for ~30 min (0808) when flew off to NW + disappeared. Paused each time a Pine Warbler gave fill-like chatter series. Looked in direction of sound + then threw arc of 50-60 deg then back to preening. Scratches over wing. Tried playback of a few songs. Bird turned to face me + began to change direction on perch through of 60 deg. Head tilted cocked at 50-60 deg. Did not leave perch. Soon after stopped playback bird resumed preening. @ 0810 - heard series of 4-6 single song, rather lengthy (1/2 min) between songs. This from S. of preening perch at least 50-75 yards. Probably same ID but unable to follow movements. 0821 - one song from SE(?) >100 yards. (very faint) 0827 - tried another playback. Bird came in from SW at ~100 feet away in pine-dead limb 25+ feet up. Sang once. Head tilted cocked + head up, only shifted position slightly.
