1982 R.L. Mumme Melanerpes formicivorus Gazebo 8 June Routine nest watch here, 0740-1040: ♂516, ♂571, ♀653 all took turns at the nest, but I saw no sign of ♀570. That would be too bad if she is gone, since I would like to get more data on the nest contributions by ♀ helpers that are unrelated to the breeding ♀. ♂571 incubated a lot today, in keeping with his now presumed breeding status. 10 June Another routine nest watch, also one on 9 June. Pretty clear now that ♀570 is probably not around ♂516, ♂571, ♀653 the only birds here. Also, ♂516 did a late incubation bout + stayed in, so ♂516 roosted in the nest. 16 June Checked the nest + banded the young nestling here: 4 nestlings, 3 of which looked pretty good, one of which looked very marginal. No trace of the two other eggs/nestlings, one of which was a runt. See nest record for details. 18 June ** GROUP UPDATE ** ① ♀570 disappeared ~ 10 May 1982 ± 1 month Last seen here 13 April. Clearly gone by 8 June. 3 July Surprisingly all 4 nestlings still alive + doing OK. They were banded J819-822. See nest record for details. 9 July Stroll by here at 0940. I find ♂571, of all things, pounding away at the feeder (=gazebo). Not sure what he was after. I also flushed a fledged juvie, but didn't see any bands. Also, Gazebo is certainly + without question OUT of acorns.
