1980 R, L. Mumme Melanerpes formicivorus Plaque (4 May) believe that the bird chasing her was ♀496! A real switcheroo! A quickie mount by ♂473 of ♀496 after tail-up mating by the ♀. ♀494 was present, and moved over also tail-up, Saw ♂521 fly off toward the Y. 0925, all 4 birds in top of Plaque tree, looking pretty happy, They may pull it off yet! 0930, ♂521 + ♀496 alone in Plaque tree top, ♂521 mild supplant, but not bad at all! ♀496 poking around the top stub of the nest tree, digging away at that hole start. She still garricks occasionally, even from nest tree. 0945, ♀494 removes sandust from hole start. Hope they don't nest there! → Watching from the cabin (idly) at 1840, another prolonged copulation between ♀496 and someone (I have to suspect ♂473).! Bird heard digging around in the cabin Blue Oak (fresh start there), plus I saw all 3 birds remove acorns from the utility pole holes. Perhaps they'll nest there, 5 May Start 0705. ♀494 works on "nest hole" (top of upper VO) for 50 sec, ♂521 barge-gleans caterpillar! ☺. 0735, 2 ♀NB intruders here, much chasing, confusion. Couldn't really tell what was going on, who was chasing, Big Magpie fight ♂521 chases! 0818, another mount or copulation between ♂473 + ♀496. As he mounted her, ♀494 flew over (♂521 was in sight, but not concerned). There followed what looked like some confusion & pecking, and I was unable to get it in the scope. Don't know if the mount resulted in a good cop. 2 ♂473 follows of ♀496. End 0830
