1983 R.C. Mumme Melanerpes formicivorus Many Plaque (27 April) the main granary. This bird proved to be 9496, and I saw her eat some of the egg for about 1-2 min before flying off. Philip reports that 9496 took the normal egg to the main granary, but wasn't sure what happened after that 28 April Boring egg-laying watch at Plague. A ? (9496?) was in the hole when F arrived at 0615, and after she left at 0627, F climbed up to the hole & found a 9496-shaped egg (25.4 x 18.4). Nobody returned to the hole before 0830, at which time Denise relieved me. Is one ? (9494) taking the day off? Could she have laid elsewhere? (I checked the 82 hole (empty) and Bos Berry told me there was no woodpecker activity up in the canyon area?) It's also possible that 9494 laid before 0600 and 9496 threw it out, then laid herself. I'll try to get here earlier tomorrow to see what time laying occurs. 1045, Denise has reported both ?Q in the hole alone twice each, so it looks good that 9494 did not lay today & will not toss 9496's egg. 29 April Good day at Plague! Both ?Q lay (see reverse + nest record), and yesterday's egg (by 9496) remains, meaning no reciprocal egg tossing by 9494, even though she had ample opportunity.
