K Dixon 1951 Bicolor 5. Mar 9. 1 mi E College Station, 370 ft., Brazos Co. Texas 9:52 one bird in oak W fence flew S[SE]; mate there was a [illegible] 9:55 peter peter peter from middle of woods where 2nd bird had flown a couple of minutes before. No more activity vocal. possibly because of my crashing over the leaves. I heard no more Adnice in next 15 minutes in those woods so I crossed road & clearing into woods to N. Passerines in general seemed to be less active than at this time yesterday. OVERCAST, calm. 10:24 - song from woods to S "peter peter" - I went back there but found no Adnice. 10: 48 teter teter teter from woods 50 yards farther S and tree* tree*tree* from woods E of firebreak. The one bird was well to the S (2nd property line at least) so I didn't try to locate it but moved N. In the area of woods with burned off ground growth (where I found pair after 10:00 yesterday) I heard song beaver beaver beaver at 11:15 and a similar song farther to the E NW. Then singer closer to me stopped and I saw a chase involving 2 Adnice in the woods some 40 ft away from me* The pursuit was earnest, involving tight turns" around tree trunks etc: NO CALL NOTES audible to me at that distance. Meanwhile song of distant bird continued. Was this a sexual chase or weather actually an interloper? Then song "beaver - -" from area where pursuit last seen but song lasted only a minute. No other call nor further activity. I moved on through the woods to S (clicksakes simultaneo 4-bird quadrel among 50 ft to S)
