1993 1994 Walter D Koenig Melanerpes formicivorus Black Oak H.NHR 3 February 1530. Counted stores: Central area: 330 (1) Side area: Main Vo : 612 other Vo : 304 1246 This is a remarkably lackadaisical showing here - either there weren't that many acorns around (but what about Bianca's fall nest?) or they just didn't try very hard. Gravany space not more than 25-35% full, I'd say. 7 April 1000. A few stored acorns remaining here, but hardly a lot. None in any holes. 28 April 830. Stores still remaining. None in any holes, however. 12 May 1030. Ditto. Surely There's a nest here somewhere. Maybe a roosting expedition is in order. 18 May 1040. Watching here for a sign of something. 1130. Bird (♀) in poison oak hole. That's it, I'm afraid! 1140. Still no changeover, Incubating? I'm off. 24 May 1600. Finally checked the hole: 3 babies, ~23 do! Est Hatch date ~May! Est LED = 20 April! Good Thing I finally got up here! 25 May 810. Veronica up here for a watch. 1200. Banded & bled the 3 babies. 15 June 1000. A quick pass revealed no obvious sign of a 2nd nest. 1994 4 February 1300. Counted stores: Central area: 1580 Side area Main Vo : 1150 Other Vo : 440 3170. Pretty respectable for a change.
