1977. Walter D. Koenig
Melanerpes formicivorus
Lambert
(8 October) Unfortunately, I messed up in closing the trap, letting one bird go—needless to say it of course turned out to be the ub ♀. In any case, I did measure and handle the other three (♂114, ♂283, ♂284). While I was doing that (745-815 or so) a small revolution had already started with >5 or so birds getting chased around in the area by the ub ♀ (who I saw later on). Some chasing was still going on at 900, 1 an hour after I’d let everyone go, but not nearly as much—the released birds seem to have been unable to calm things down very quickly. Nevertheless, despite the season it was clear that rep new recruits were readily come by and were already queuing up to get in the group as early as 1 hour after dawn!
900. Watching now. Still some chasing.
→ #97! (see below)
907. One intruder seen: ? Blue-white/Red-white #358 ♀ (caught at the Near Lambert revolution 7 April, not seen since). This bird flew to near the middle tree, then heated off away from me.
925. Leaving. Still chasing going on, but things do not seem to be escalating. Several ub birds seen, inc. ♂1♂ and ♂2♀.
*The banded intruder seen above at 907 may also have been (and in fact very possibly could have been) ♀97, a bird banded as an adult at Black Oak in 1972 and not seen there since 1973!!! Unfortunately I have no good way to tell at this point; clearly ♀358 seems more probable on a purely logical basis.
Purple: ♂202. Last seen on 26 January, gone by 7 April
→ Disappeared about 3 March 1977 ± 1 month
♂116. Last seen 7 April, gone by 11 May →
→ Disappeared about 24 April ± 2 weeks
