1977 Walter D. Koenig Melanerpes formicivorus Gate (18 October) in order. The present listing is given on the back of this sheet, along with the changes I'm making, which are, basically, to assume that the 2nd unbanded ♀ that's now here (and has been for some time for sure) fledged here in June 1975 (rather than mysteriously appearing in fall 1975); and ② to further assume that the 2nd unbanded ♂ that's here now (and was first definitively observed on 23 November 1976 after one other unbanded ♂ was caught in March 1976) also fledged in June 1975. This gives this group 5 babies for 1975 - a not unreasonable guess as to how many they in fact fledged. Rather less likely is the further supposition that 4 of 5 of them still exist at Gate, but it still seems like a not relatively harmonious solution to the problem of accounting for all the birds here. If only I could catch some! Another change I'm going to do is to view the takeover of Gate territory as just that: an expansion of Group Westgate to include Gate; not a "movement" or "abandonment" of the Westgate territory by those birds and a move to "Gate". Thus, on my list, this group will now be "Westgate" again rather than "Gate". 29 October 1330. Going to try and see some of the babies here. ①♀ 1345. ①♀ub. Light not so good. 1400. ③♂/Red = #396. These birds are mostly up the valley a short ways (past the Gate on the Haystack Hill side) apparently getting acorns. 1405. ①♂, 2♀ or #238. 1415. Leaving. Things aren't working out. Come back in the morning.
