1979 Ronald L. Mumme Melanerpes formicivorus Bianca Hastings Reservation 24 March Start watch from hide 1610. 1640 ♀ Anna's Hummer drinks from sap wells on Blue Oak, where Walt says Bianca birds have been sapsucking. Anna's there < 10 seconds, but checked several wells. Pair of Nuttall Woodpeckers (♂ silver banded on right leg [illegible] light green (?) on left) worked over sap wells several minutes. Also two White-Breasted Nuthatch, ♂ + ♀ (Walt says a nest nearby) working sap holes, about 5 minutes. Banded ♂ Nuttall flies off, but ♀ (unbanded) continues to work sap holes. 1700 and she's still there, now about 15 minutes 1703 ♀ nuthatch back. ♀ Nuttalli' supplants ♂ Nuthatch, ♂ Nuttalli' doing much valley oak drilling and tapping in [illegible] behind me. 1710 Plain Titmouse arrives, checks out a few holes 1712 ♂ nuttalli calls, ♀ finally flies off. ♂ Nuthatch still around. End 1715. Red-breasted Sapsucker, too. 12 May Up here with Walt, we saw a genuine low-intensity revolution. I had only my 20x scope, but according to Walt, there were two of the Arnold's ♂ plus two (and briefly a third) unbanded ♀♀. One of the ♀♀ seemed to have the upper hand, continuously chasing and supplanting the other. The ♂♂ did almost nothing, and the ♀♀ seemed to follow them around. The ♀♀ especially (it seemed) the subordinate ♀, drummed, garricked and yabbled quite a bit. 22 June Start watch 1015, Two birds seen here, one a ♂ which
