1987 M. Stanback M. Formicivorus BKOK HUNHR 10 April 1030 Bird at P.O. hole on arrival. Went inside. 1500 Climbed. Empty - there were wood peelings + a little moss inside. I left it. Too much P.O.! 12 April 1630 - 1730. Spied unsuccessfully. A bird seemed to flush from the hole toward Lower Bian. I set the blind. A nice new hole is being built facing wsw. in the tree just S of the lower snaggy tree. It's in the base of a stump. 13 April 1420 Damn, I'm good. The far hole in the BKOK is the one. 9 1190 was working feverishly on it, bringing out mouthfuls of chips. 8 426 could also fit inside, so it must be getting ready. There was also a third bird in attendance. See map on back. → 14 April 1230 Came by and bird was in hole. Put up string. 15 April 1230 Bird in hole on arrival.
