1981 R.C. Murme Melanerpes formicivorus Mary Blom One (18 May) 'Nest' check 1300. The 2 eggs that Walter reported in the pond-facing hole are gone! Hole empty. Definitely a false start. 20 May Start 0555. 0655, Nice dominance interaction between ♂493 + ♂622. The 2♂♂ and the 2♀♀ were all together on top of the big Blue Oak (with the holes) 20 m E of the small dry cattle pond. ♂493 gave ♂622 some very sharp, hard pecks (4-5), to the head of ♂622. At the same time I believe that I saw ♀648 chattering to ♀649, Would like to nail down that relationship. Looks like ♀649 has a nice strong double mustache on both sides of her head, while ♀648 has a much cleaner face, with only the slightest hint of a single stash. End 0800, No interest in any holes. I believe that I saw somebody really trying to peck ♀648 away from a main storage limb, with ♀648 chattering away. Wasn't sure if it was ♂ or ♀ aggressor. 22 May Watch 0610-0745. No interest in any holes. Only thing of note was dominance intention: ♂492 pecked hard at ♂622, in the granary. 24 May Start 0610, 0700, Up until now ♂492 + ♀649 have been alone in the granary. ♂493 + 622 (process ♀548) → Fly in from Blom 2. ♂492 then pecks hard, even climbing on back, at ♂622. ♀649 present, 21m away, in top of granary, 0730, Quitting. Birds all up on Haystack flat. Still no interest seen in any holes. When will they?
