1993 M. Stanback M. Formicivorus 2 MPHE HNHR 13 June 0830 Saw 1962, 2080, + 2081 (I think) across road towards Radioactive. Flycatching like mad. 16 June Walt reports 5 eggs fresh 22 June 1100 RL = 7.6, LL = 7.0, RW = 6.7, LW = 4.0. There was 1 unhatched egg (no pipping, no peeping). I Figured by the time it hatched, it'd be a goner, so I removed it. Back at the lab I opened it. Quite alive, but still had large yolk sac, had not pierced air sac either. It had ~ 24 hrs to go I'd guess. I made a tissue sample (#2327) since I'm keen to see if T implants have any effect on paternity. Sorry little guy, Est hatch async: 11.6, 10.0, 8.7, 5.0, 4.0 24 June 1300 RL = 19:0, LL = 14.3, RW = 15 = Mv, r = 8.8 Runt looks OK (sort of), but I'm still convinced that a chick hatching 24 hrs after him would die. New Est For 23 June: 12.6, 10, 10, 6, 4
