1977 Walter D. Koenig Melanerpes formicivorus 1800 (2 June) phase of a larger more vicious revolution which I missed entirely. Right now, ♂334, a 2nd♂, and ♀260 are sitting quietly in the main tree. Looks like if anyone's getting replaced, it's dear old ♂43. 1425. ♂DB-LP/DB #193 here, ♀ is begging profusely (acting submissive), was still displaced once by ♀260 (but yet is not getting really chased). 1430. ♀260 and ♂334 in Main tree now. The School Hill 1st yr birds are apparently sticking pretty much to the other side of the territory. There are several other birds in the forest behind me, though. 1455. ♂m/2eb #191 here also; still no real chasing even by ♀260. ♂(u6?) tailless. 1500. Another bonus bird: ♂LP-DB/LP #347 (also from Poison Oak Hill!). 1510. Leaving. My tentative conclusions: ① ♂43 should have been seen if he were here, but wasn't. ② ♀260 wasn't really chasing anybody, but there really were only 2 ♀♀ here at all consistently (♀191,193); they were displaced now and again and did give lots of submissive calls. ♀260 was probably more interested in the ♂♂, whom she greeted with typical alacrity. ③ The 1500/School Hill crowd (♀♀296,297,298) were definitely only peripherally involved at best, by this point. ④ ♂334 was present the most in the main tree, followed by ♂♂ (tailless) and ♂347. ♂43 is most likely to be replaced by one or a combination of the above.
