2002 2003 Walter D Koening Melanerpes formicivorus Lambert HNHR 12 April 1045. No stores left, best I can tell. Pretty quiet up here. 25 April 1220. Doug had reported a bird in the 2001 hole, so I checked it: in good shape but empty. 8 May 1205. Opened last year's hole again; still empty. 22 May 1030. And it's still empty. 17 August Presumably was a group here this spring (Joey saw 3 birds on 16 July) but we've failed at getting much of a fix on them since early spring. No nest and no stores, at the most! 2003 19 April 1130. Bird in hole (tag 1315): 1 fresh egg, marked (25.7 x 21.1). Stores here: yes. 21 April 1310. Check hole: still the 1 egg (!) 26 April 1225. Still the 1 egg - and it's developed! They're apparently incubating it! Wow. A real 1-egg clutch! 10 May 945. Hole empty. Yet another weather casualty, I dare say, directly or indirectly. 20 May 1215 Bird in (same) hole: Legg, not so fresh that I'd swear they're going to lay more. Size: 25.4 x 22.0 (as close to a ball as any I've seen!) Another 1 egg clutch! 30 May 915. 1 baby, ~2-3 do. Band ~ 17 June. Ambusher set as in case there are NOBAs. 10 June 1600. Hole empty! There are definitely still stores here, by the way. 18 June 1630. Bird in new hole, in lobata or Bradley's
