1992 Walter P Koering Melanerpes formicivorus MPHF HNHR (28 April) this would appear to be a clear case of restraint on the part of ♀1533 ending egg-tossing. See back for my best guess as to the sequence of events here. 29 April 620. Watching. Nest still with 4 eggs (3N, 1R). ♀1533 enters hole. 717. ♀1533 enters; ♀ now looking out (♀1531?) 714. 1 bird left. ♀1531 Yes 750. 2nd ♀ (1533?) looking out, leaves. 752. Going to check hole. Only 1 new egg (#5)! Can't be sure, but, given ♀1533's late laying yesterday, my guess is that it's ♀1533's. (Egg also did not seem that warm; i.e., as if it had just emerged from ♀1533). 30 April 618. Watching. 653. ♀ leaves! Bummer - no ID on this bird! Well, surely it was ♀1533, who is now preening atop the other tree as if she'd been confined for some time (i.e., in the hole). 700. 6 eggs (5N, 1R). Other evidence this egg was ♀1533's: bird in hole early, never looked out until she left. Very unlike ♀1531's behaviour any of the past several days. 800. No one else came to hole. Either ♀1533's going to lay very late or she's taking the day off. Leaving. 1800. And the answer is: Late! Now 7 eggs. See back for measurements. 1 May 620. Watching. No one looking out of hole, but someone could be inside. 645. ♀1533 looks out & leaves (ID's on branch preening after her exit).
