1978 Walter D. Koenig Melanerpes formicivorus Y Hastings Reservation 14 June 1145. 8415 seen in the locusts in front of the barn chasing an Oriole. 15 June 1115. 8415 at the new hole in the '75 nest tree. 1635. 8415 and a ♀ (no wing streamer) sitting in front of the barn quietly. 18 June 8415 seen around here twice today along with 1-2 other birds, neither of whom seemed to have wing streamers. 19 June 900. 9434 (YLW) down ½ way toward Pump. Watching. A 2nd ♀ by the barn. 9434 looked pretty furtive (only behavior as seen). 905. 8415 & 9434 by barn now. 913. Voilé: 9434 just joined 8415 in front of barn. 925. Well, both banded birds are still here (8415 regularly, 9434 relatively scarce); (the 1ub ♀ apparently still hanging around but I was unable to get a good fix on her this time. No sign of them eating any stores. Things rather quiet, all in all. 2 July 900. I was standing at the Y when I looked over toward the knoll and saw a Cooper Hawk flying along. Soon I realized he was chasing after an A.W., who was no more than 40 ft ahead of him, Flying along without the usual woodpecker lift. The two birds circled around, once or twice with the woodpecker dropping suddenly and changing directions entirely, for over a minute, heading up School Hill. Eventually both disappeared from view for 20 seconds or so well & up the Hill, probably near the nest tree. Then the woodpecker reappeared, calling (krrr-krrr) [the first calls I'd heard] heading in the direction of Red House. I lost him soon afterwards. The whole time the hawk was no more than 50-60 ft behind him on his tail, and occasionally seemed nearly to nail him, coming within several feet. The woodpecker stayed up in the air, however, until he disappeared
