1992 Waltu D Koenig Melanerpes formicivorus MPHF HUNTER (27 April) 840. ! Almost sure I had a brief look at a bird in the other nest tree with a large (normal) egg in its bill! Ang! Bird disappeared immediately. Would appear as though #1533 is laying, but somewhere else! Note, though, that it's not one of the 2 regular holes over in that tree either. Where are they laying? Or did I imagine this? No, I think not... 850. [illegible] #1613 on the limb; flew off. 930. Well, shit. What's going on here? Looks like both are laying; unfortunately, where #1533 is doing it is a mystery. Leaving for now. 940. Checked the hole on the way out - eggs are both still there. 1900. Watched roosting - found a new hole (upward- facing knothole) in the upper nest tree. Birds roosted there and in the high hole above the nest. 28 April 530. Opened the knothole. 615. I'm watching the knothole, Jim & the VCR are at the other hole. 800. Well! Here's the poop: no action at the knothole. However, 2 eggs were laid in the other hole - 1 by #1531 at 700-745 (ID by behavior of the bird at the hole, not by bands), and the other (#1533, presumably) laid late, at 749-800. I presume this is her "last" egg (i.e., that #1533 will skip tomorrow). Eggs were marked 1-4. Note that both #s came by themselves and had noone else visit or even check the hole while they were inside. Hence! [illegible]
