1977 Walter D. Koenig Melanerpes formicivorus Black Oak (5 May) 19 November 1976 over by lower Arnold 2 during the ♀-replacement there. Gone, apparently, by 22 December, → Disappeared by about 6 December ±2 wks. 6 May 1430. Things rather quiet here; nobody in holes. 10 May 1700. Relatively lots of wakea calling coming from here. Nobody in holes, but 5 birds flushed from the central area as I walked over to it. 13 May 1245. 24 birds, all wakeaing as I approached, flushed out of the central area. Counted stores: 1256, all in central area. 22 May 1400. ♂ in the infamous '75-'76 nest hole both on the way to and back from Bianca. Definitely could be it. 24 May 1615. Bird in the hole again. Must be it. 27 May 1120. Bird in hole; hole opened; 4 eggs. 31 May 1110. " " " . 5 June 1540. " " " . (♂) 14 June 1900. Opened the hole+measured the babies, of whom there are only 2. 17 June 1310. Watching from hide. 1325. Cooper Hawk flew by, eliciting several alarm calls by at least 2 invisible AW in the area. 1420. There are birds here- I keep hearing them in the forest behind me. But nobody's come into view or gone to the nest yet. 1435. Finally, (♂) m/ds-yec(n) #321 fed the kids. 1540. I'd say this doesn't seem to be a real big feeding period. I'll have to try again another day. Counted stores: 737 . 19 June 1115. Watching from hide. None apparent offhand.
