1992 Walter D Koenig Melanerpes famicivorus Keep Out HNHR 1 January 1615. Counted stores here: Main tree: 680 7695. Other area: 15 30 March *Group update* Everyone gone except for 81127 and 2 NOBA ♀♂ behaving fairly new on 3/25. 20 April 1830. Here watching roost. 1910. 3 birds here; lots of pre-roost mounting. All roosted in The hole in the granary. 8 would be easy to ambush. 29 April 1130. Fair amount of activity here; even a little chasing & drumming. ♀NOBA seen (1, anyway). 1135. Definitely either a couple of persistent intruders here or some residual "power struggle" activity. Maybe the ♀♂ aren't completely settled here after all. 2 July 600. Caught 81127 and (finally) ♀NOBA (now 2125) in a hole in the Live Oak (2nd nest hole). ♀ wouldn't come out - finally had to saw the hole open to get her! 25 August Valerie found 81754 dead on the ground slightly up the canyon from the granary (Maybe 100-150m up away from the granary and Hastings). She had seen the bird earlier (on 20 Aug) up in a tree, dead. It's not at all obvious what happened - he's tried up and contorted now and has no obvious wounded wound. ?? What happened? 3 December Another unexplained casualty: a ♀NOBA, dead in a hole in the burned Live Oak; she'd been there quite awhile, perhaps a month at least. What's going on here?
