1983 R.C. Mumme M. formicivorus Low Hay 16 May Watched here, 0545-0700: No eggs in the hole when I checked it at 0700, and only 9524 made 3 quick visits (though 9587 looked in a few times). Still domestic problems here: A ♂ chased 9524 fairly vigorously or at least two [illegible] occasions. 18 May 0545-0700, Looks like we could be getting close here. Both 9524 + 9587 spent a long time (~35 min for 524, ~20 min for 9587) in the hole simul--Wow! Hddo-. Anyway, both 99 were in Simultaneously between 0625 and 0655. However, I did not see 9587 leave, and I thought she was still in the hole when I went to check at 0700. I found the hole empty. However, while writing the above at 0715, I heard a big chase going on [illegible] (chase originated in the 1° gradary) To my considerable surprise, I looked up and saw two birds chasing a third bird that was carrying an egg! This bird was chased eventually to the 2° gradary, where I was able to scope it briefly (a ♀ for sure, but I couldn't see the bands) while it ate a bit of the egg before flying off. I was able to climb up to the limb where the egg was deposited, and I found a fragmented egg, all liquid gone, but length still measured 26.4. It fell apart before I could get width. What happened? Did a ♀ lay in a different hole? Did 9587 remove the egg when I missed seeing her leave? Did I miss the egg when I checked the hole? We will have to find out tomorrow.
