1981 R.L. Mumme Melanerpes formicivorus Low Hay Low Hay (4 April) ♀509 doing sonedrumming. Saw ♀587 drum once in the granary. 1545, a real fall at the moment: 1555, 2 inexplicable, ♂461 starts to tussle with ♀509, after sitting "with" her for quite some time. This attracted ♀587 from the granary, who gave violent chase. Then, all resident birds in the granary, waking, etc. ♀587 open wings, tail lifts as well. Intruders seem to have been temporarily routed from the scene. End 1600. Score Round 1 to ♀587. 5 April 1035, Revolution in full swing. ♀523, ♀509, 3 NBQQ here 2 NBQ seem to be cooperating. ♀523 is peripheral (broken tree SE of granary) as is ♀509 (2° granary). At least 4 x pursuits 5 ♀NB. One peripheral on the utility pole. Peripheral birds (♀523, ♀NB) do all the garricking. One big "to the ground tussle" I try to run up to capture them, but they take off just in time. On the ground about 1 min. 1118, ♀587 does all the chasing in the granary. In the 2° granary, ♀509 has a little sidechon with a ♀NB. ♂307 does a bit of chasing, especially it seems when on storage limbs, the 2 NBQQ that are cooperating seem to chase peripheral ♀Q, but themselves are being chased by 1300, a long fall to set up mistnets, ♀587 captured. ♀523, ♀509 still around, but doesn't seem like a pair of cooperating females anymore. 1400, Pause after catching ♀523 in the net. 1500, 1600 Caught 2 NBQQ, [illegible] Before catching the second one (♂642), we had seen rowings between
