1977 Walter D. Koenig Melanerpes formicivorus 4 Hastings Reservation 2 April 830. 0♂ RRL #322 in locusts; no chasing to speak of by the barn, but there are still 4-5 other birds on the knoll. Also in the barn area now: ②♀ Orlw #16, ③♂ Red/M #364, ④♂ DB-LP/DB #261. 900. On the knoll are the 1500-School Hill birds again - seen were ♂296, and ♂298. Monica watching here; as she will continue to do for just about every day until we find a nest here or are interrupted by Plague's nest. See her notes for daily reports. 23 April 1000. ♂297 (School Hill (?)) and ♂326 and 2-3 others still up on the knoll here; possibly beginning to be chased [by the residents]. Watched here this evening. At 1905 3 of the birds in the small Blue Oak sap tree by the knoll (no doubt the 1500-S.Hill complex) headed off together toward the lower end of School Hill (about at the old unused tree) followed several minutes later by a 4th bird. The Y birds, meanwhile, were apparently in the Valley Oak by the fence just over on Borquist's the whole time, for Monica saw 3 of them depart simultaneously about 1915 and I saw all 4 arrive together in the Squareone, where they no doubt roosted. 30 April This morning several of the wing-streamered Y birds were in the '75 nest tree, while 3-4 others (presumably the "1500" birds) were further out on the knoll in the perch tree. There was a lot of calling here yesterday (when Monica wasn't able to watch) and I suspect that it all relates to the gradual recovery of the knoll by the Y birds, which has been under the control of these others since I trapped them on the 20th. They were showing
