At 8:20 along the tributary to the E sang peta peta (windmills nest area). I walked S through post oak savanna which changed to mesquite - liveoak about 1/2 way to the SE trending main branch of the creek.

WIND moderate from SE AFTER 8:15 I heard no thrice in vicinity of big oak visited March 31 and think that singing S to W was the same bird oler than that date. I walked S to where the creek swings SE leaving whitish bluffs to SW.

Here at 7:20 - it was singing tur -- -- and I followed it along -- peta peta from east of creeklet at 9:25. I managed a shot at this bird with a .38 & missed - it flew to post oak 20 yds E of where I had shot at it calling ver vet vet over & over. Then bird flew S for several trees in succession singing "peer peer peer" keeping ahead of me, singing steadily. Then it flew into liveoak covered with staminate catkins,
