1977 Walter D. Koenig Melanerpes formicivorus Black Oak Hastings Reservation. 25 January 1200. Counted stores: Central area: 1466 Side area: 452 } 1918 Also removed a sample of 55 acorns from the central area. I was able to pick out discernable traces of color on 7 acorns in the one dead limb that were marked last year. Some of these were quite faint, however. 11 March 930. Counted stores: Central area 1384 } Side area: 321 } 1705 13 April 1030. There is a fair amount of apparently mostly intragroup activity here, especially in the side area. Involves 4-5 birds. 1040. 1030r/DB-3821. 1042. Some Carrick displaying, lots of wakas, but I don't see any chasing. A ♀ is paying attention to the hole over there covered by poison oak. 1045 Apparently some sort of interaction is taking place; there is possibly one intruder. At least 1 ub ♀ is here. 1050. The ♀ at the roost hole is @♀ub. 1052. There definitely seem to be a few more ub birds here than there should be; also I finally saw a couple chases. 1055. There in fact seem to be 3-4 ub birds here. 1130. The story as far as I can tell is this: there are possibly only 2 38, 3821 and an ub ♂. There are 4 or 5 ♀, however, none of whom are banded (best I can tell. Some chasing, Carricking, etc., is taking place, but if there has been a complete change of ♀♀ and these are replacements the brunt of the revolution probably occurred several days ago.
