1982 R.L. Munme Melanerpes formicivorus Plaque (16April) 0710, ♀494 lands at hole, enters immediately: 0712, ♂521 looks in, enters: Both ♂521, ♀494 in hole together. ♂473 looks in for 30 sec, flies off without entering. 0716, I hear tapping from inside hole. 0716: Uh-Oh, ♀496 enters the hole; 3 birds all down inside hole 0719 ♂521 looks out. 0722, One of the ♀ leaves with wood chips. Judging by the fact that this ♀ was not followed from the nest by ♂521, and by the fact that ♀496 has been removing a lot of wood chips the last few days, I'd say ♀496 left at 0722, ♂521 continues to look out. All 0724: ♂521 leaves, second ♀ (♀494?) looks out. She has a very thin black line from the closure of the bill through the white bar of the face. She leaves 0724, too: Checked hole by peeping: Anot unexpected new egg: There is some doubt about ownership, since both ♀♀ were in the hole while it was laid: But I'm fairly certain it was ♀494's for the following reasons: ① This egg, ever by peeper, was definitely shorter + rounder than yesterdays egg. (♀494's eggs are usually not as long + narrow as ♀496's). Definitely not a raut! ② ♀494 entered first + (presumably) left last. ③ ♀496 has been removing wood chips, Behavior not appropriate for a laying ♀. 0728 Back in the blind.
