1989 1990 Walter D Koenig Melanerpes fornicivorus LA2 (2 August) Other areas: 500 (few acorns at the moment) Total ~ 5000. 1990 18 January 1540. Counted stores: Main tree: 4280 Other areas: 786 These birds have done an amazing job of recovering from the fire: the burned tree has holes densely packed in all sorts of places - all drilled since the fire. I'd put capacity at about 5300 - there aren't many unused holes at the moment. 2 April 1055. 2 birds in the "Top" tree flew back to LA2. I checked last year's hole in the Black Oak just past there, but the limb broke and the hole is gone. Lots of acorns left here. 22 April 1000. Chasing! Some genicks! A power struggle? ①♂ Or/DB-wh(n) in granary. I take it back: this looks like ♂BTE-wh(n)/LB #1234 from Big Tree. He is pretty well ensconced in the main tree here. ②♀ -LB/Red #1371 drumming next to ♂1234. Possibly 6-8 other birds here. Does this mean the end of ♂611?? ③♀NOBA, drumming; now chased out. Holy! Wow! ④♂ Mr./Bla-Dea #611 is here! ♂1234 must be a son.... This is perhaps merely an unprovoked uprising? ④♀M/Red #1753 (seen well) in back area defending one of the trees. ②nd ♀NOBA. 1100. Not sure what's up, but ♂1371 and ♂611 are definitely both here so there's no vacancy, at least. But, I saw no sign of ♂1116 or of either
