2001 Walter Koenig 2002 Melanerpes formicivorus Buckeye HNHR 30 April Bird in new hole up in the same Valley Oak they've been nesting in. 1 May 1530. Opened the hole (now tagged #1309): 6 eggs, 1-2 days incubated. Measured then: ① 23.9 x 18.8 ② 24.0 x 18.9 ③ 24.4 x 18.6 ④ 24.1 x 18.5 ⑤ 23.7 x 18.8 ⑥ 24.2 x 18.5. Also set an ambush, since there's still apparently a NOBA (? ) here. 12 May 1645. 4 babies, ~5 do + 1 unhatched egg, Band ~ 27 May. Ambusher ready, 31 July 0500. Ambushed the nest hole, getting 5 birds, including (yes!) The 8 NOBA! 16 October Ambushed this morning, getting 4 birds in the old (low) nest hole, but no NOBA (there is apparently still 1 more 8 NOBA here). One of the birds I got was 82828, a 1997 nesting NSAB!! 21 Nov. 0700. Another ambush up at the nest tree yielded 5 birds (the low hole they didn't use this year), including 83433, 83432, 83627, plus 2 (count them! 2) NOBA 88s, both AHY, and thus presumably from that missed nest in 2000 unless 83065 isn't there anymore. In any case, hopefully this is the lot of them! 2002 23 April Plenty of stores here. 6 May Still stores, but none in a hole
