1985 Walter D Koenig 14 Melanerpes formicivorus 1800 HNHR 15 May 1045. Weighed the babies. 17 May 1630. Injected the babies for DLW; weighed them at 1630, injections completed by 1638. 18 May 1730. Weighed and bled the babies. 19 May 1740. And again... 28 May Missy watched here 800-1100, after which I added two additional babies from Plague Annex. Day was foggy in AM. 29 May Missy watched on a nicer day (clear, but still cool), after which I returned the 2 babies to Plague Annex. 1 June Last watch day (Control Day #5). Afterwards I banded the babies as #1093-1095 27 June 940. Watching. There are 3 eggs in the hole, 2 by 8193 and 1 from 8787(?) 1050. By now 4 birds - 8193, 8985, 8770, and 8771, have been in the hole. 8985 was in the longest (mostly while 8771 sat outside the hole); nobody tossed, however. Right when 8985 finally left, 8771 climbed out of the hole and went over to 8774 who had just landed nearby and pecked 8771>8774 him, then jumped on his back and pecked him again. Otherwise, 8771 is clearly guarding 8785, 8770: 8193. I didn't see 8787 at all. 1100. Climbed up and checked the hole: still 3 eggs. If anyone tosses, it will have to be 8787 (or 8774!). 2 July Mark has been watching here every morning. There are now 8 eggs, with all 3 8's contributing (and with tossing too, but we were unable to pin down much on that score). See Mark's notes for details.
