1976 Walter D. Koenig Melanerpes formicivorus New 1500 Hastings Reservation (29 March) 930. 2 birds, including 844, flew up into tree 1. A chase ensued, in which one of the birds was forced out of the tree, flying over to the lower sap side. Left in tree 1 was an unbanded 8, presumably #371 but if so why was she chasing the 8? (unless he has "forfeited" his position here by having "returned" to 1800 since the stores ran out here).

After the first set a Cooper's Hawk flew overhead, perhaps explaining it. 940. 8 still atop tree 1, eating leaf buds. Just gave another two Garrick displays. 945. 844 flew into tree 1. No chasing or greeting; 8 flew to tree 2. Both in their respective trees for several minutes. 950. 8 hawking from tree 1. 8 not in evidence. 952. Found 8 - still in tree 2, probing into storage holes in outer snag pointing toward tree 1. 954. 8 flew to tree 1, not near 8 but with wake calling. 955. Both sitting in 1. Me going. 11 April 1000. Two birds seen flying from tree 3: I was 844 who flew to the upper sap side, the other headed toward Pump. Where there was an unbanded 8 (plus an unbanded 8) foraging a minute later. See Pump notes for more details. 18 April 1740. 36 birds seen in 1; somebody getting chased. Only 2, 8 (?) and a 8 unbanded after a minute. 22 April 1720. Watching. 8 unbanded showed up eventually in tree 1. 1732. A bird suddenly flushed from tree 4, right above me,
