1984 R.L.Mumme Acorn Woodpecker Dark Hollow 23 April 0630-0730, I confirm what Denise has been seeing. Dark Hollow now has is 1982 composition: ♂584, ♀695 M/Maute and ♀696 or-wht/or-Blt, all here + seen well. Also a lot of intrusion, including ♂721 M/Lw-Yellow from Plaque. 15 May After flushing a ♀ from the 83 nest hole, I return with the rope ladder but find no eggs. 16 May Watching here 0605: Su-uvagu-, at 0705 ♀695 entered the hole, left at 0725. I climb up and find 1 Fresh egg 26.1 x 19.1 mm. Nothing really unusual about the egg. All 3 birds (♂584, ♀695, ♀696) see well. By 1100, Nobody except ♂584 had entered the hole, though ♀696 had taken a good long look at it. With Beth watching with me, a long wait but 1145, ♀696 enters finally, then flies out immediately with the egg in her bill! Yeah! Carried to the 82 nest tree, but then I lost track. Yessir, ♀695 laid, ♀696 (the victim the previous two years) tossed! Beth's first egg toss 17 May Watching 0615 0740, Nothings up. Both ♀♀ paid brief visits to the nest, But no eggs laid. 19 May Watching 0555. 0608, ♀696 enters, ♀695 follows at 0615. ♀695 leaves at 0625 followed by ♀696 at 0630. Both ♀♀, there plus ♂584, were there in and out of the hole a few times. At 0640, I climb up to the nest and find one fresh egg, probably laid this Am between 0608 + 0630 Laid by ♀696. Didn't bring the calipers, but the egg is fairly round, heavily marbled, 4 birds here breeding male (♂584)
