1991 Waltford Koenig Melanerpes formicivorus Westgate HNHR (19 May) As I pondered these mysteries, Danny came along to do a watch so I left him here, partly on the assumption that the egg should get tossed. (Presumably by 91473, but why hasn't she done it already?) 1215. Went down to check. Danny reports lots of visits by both 99; 91473 was in for ~20 min after I left this morning so I checked the hole again to make sure she hadn't laid late: still the #1 egg only. Hence, someone (presumably 91473) is showing laudable restraint here, leaving until tomorrow morning! 20 May Only 1 egg laid today, again (apparently) by 91415. Both eggs measured. No indication that 91473 wants to toss! Transcription: 613. Start! Noona around. 619. Bird tipped into hole. 8. 620.

Leaves! 714. 803. 91473 enters (91415) 805. 81582 at hole. 806. 8 leaves 810. Check hole. 2 eggs. Both same width; Both 91415. 21 May 830. This continues to be an interesting group! Watched this morning; 91415 gave every indication of dominating the proceedings and laying another egg; I wasn't so sure about 91473 but she was in for a bit late in the morning and so could also have laid. The result? 2 new eggs - both of 91415's older ones finally tossed! I guess 91473 finally woke up after all.
