1981 R.C. Mumme Melanerpes formicivorus Gate (30 April) Outside, I flush them out, and they fly off in a very tight pack of 3. I go up to the "nest" and find (once again) no eggs. But the bottom has a much nicer cushion of wood chips than I remember from past checks 1520, watching for awhile here. ♂♂ still definitely hot following the ♀. May even be showing more tight packing than previously. ♀601 is missing again 4 may Nest check at 1700.

Saw pre-roost mounting between the ♂♂ (with no aggression) Late, I saw ♀519 fly to a ♂ and give a precopulatory
