1982 R.C. Numme Melanerpes formicivorus Bianca (11 Dec) the knoll perch tree. Further down the ridge, and especially in the VO furthest down, there are a fair # of acorns, and I've not seen any of the BO birds down there. What's more, the BO birds are carrying the acorns they gather back to Black Oak. So I would guess that Bianca is still occupied by NB birds. I saw a ♂+♀NB on the knoll chased by Black Oak birds, so those could have been the Bianca residents. 1115, yes, down in the core Bianca area I see a ♂NB and a ♀NB
