Walter D Koenig 1991 Melanerpes formicivorus H N H R 4 January 1050. The granary here is, of course, a locust, which are virtually impossible to count because of the bark. However, I gave it a whirl anyway and came up with 333 acorns. This at least places the granary into a ballpark size class; my guess is that it holds perhaps 1000 acorns and is ~60-70% full. 13 April 915.9 M/Dg #1580 in front of barn. 920.8 NOBA! Looks like a new 8 here? Haven't seen them together yet. *Group update* 8 March/Mo 81150 8 last seen 4 Feb, gone by 13 April → D.A. [illegible] + [illegible] 22 April 515. After the apparent turnover here I tried to find where roosting was. I finally tracked ≥1 bird into the high hole in the sycamore across from the lower barn near the telephone pole (the cutoff limb; 2 inches below the cut). Last night 1 bird went in, but then 2 more birds came by, eventually (after some commotion) heading off toward Knoll. This clued me into the possibility of some weirdness. The ambush this morning yielded a ♀ NOBA (now ♀1910) - not the ♂ NOBA I was hoping for. So who knows who this bird is - not me. Mark Stanback had mentioned he had a ♀ NOBA up at his feeder a few days ago, so maybe it's her? If so, presumably she's just wandering through (a real floater?). Unfortunately it means I still don't know where the Y birds are roosting. 26 May 1615. Checked the locust hole: empty (but birds were at it). 845. (6) babies and no unhatched eggs! - No! 5. See 29 May.
