1979 Walter D. Koenig Melanerpes formicivorus Black Oak Hastings Reservation 3 January Took a sample of 25 acorns from the granary, replacing them with my own. 6 February Counted stores: 478. No sign of any birds here, however. 9 March Still stores here, but no sign of any birds. 10 March 1045. 3 yel / 4nt #102 in perch tree, flew over to Al area (!) 11 March 1700. Once again, a bird up in the perch tree (probably 3 102) flew over to Al, then back. In addition, a 2nd bird was involved somehow, seen at the end preceding the 3 back to the Black Oak area from Al. 23 March 1 3 sitting in the sap tree which the birds here used last year (between the perch tree and the central storage area in a live oak) at about 1430. 19 April 1015. Watching. Nobody immediately in evidence, but there are stores here. 1035. 3 here briefly sapsucking, then took off. 1100. Now 2 38s and 1 3 here; 3 3 sapsucking. Are not who I expected: 1 3 Bilk/or #426 and 2 3 M/-wn(w) #321. Humm. (both these birds had moved to Bianca, or so I thought). 1112. 3 is hard. 3 3 or-wn/M ...this would appear to be 3 320, not seen here since last spring, and deleted long ago. I still need a convincing look, however. Meanwhile, what's happened to the real Black Oak birds? 1120. Now 4 birds here - 3 in sap tree and one in perch tree. 4 3 yel/la #102. Hum. Sapsucking with other 2 38s. 1130. Looks like about it. I'm moving to see what, if anything, is up at Bianca. I'll have to know more before I can figure out what to do here.
