1991 Walter D Koening Melanerpes formicivorus Westgate HNHR (8 May) Meanwhile, the 2 helper ♀♀ would almost certainly appear to have gone, as a result of the ♀ turnover if not earlier: ♀1741 last seen 9 Jan gone by 12 March → DA 10 Fe6 ± 1 month ♀1889 " " 12 March gone by 6 April → DA 25 Mar ± 2 wks 12 May 640. Watching. (1) 6 da/yel #1585. 710. Going to road hole, though not enough to suggest eggs or laying yet. (3) ♂ LB-w/m #1582. (3) ♀ Red/LE-DA ??? Not quite #1415... OK. It is R-16/DA #1415. 730.♀ R/M #1473 here. Birds also still paying some attention to both holes in the vertical limb. 745. Leaving. Still looking promising but not there yet. 13 May 700. Still farting around in all 3 holes, at least. 800. Some mate-guarding (such as it is) data on back. 14 May 640-815. Some more (lack of) mate-guarding. Some Interest in all 3 holes continues. Wood chips still being removed from the road hole; I think they're close but not there yet. *Group Update* ♀91415, 1473 moved here ~15 April ± 2 wks (from Cazebo) These birds moved in after the former breeder ♀♀ here (who are presumably the mothers of the breeder 88) abdicated (invest avoidance!) and shifted to Gate (note that they'd been playing with This all winter). Actually, only ♀1571 definitely went through with this; ♀1688 has disappeared and could very well have gone elsewhere. Both events will sort of arbitrarily be placed on 1 April.
