1978 Walter D. Koenig Melanerpes formicivorus Lower Haystack Hastings Reservation 3 January Collected a sample of 100 acorns from the granary. The main tree here lost lots of small peripheral branches in the storm, but apparently no storage areas. What did fall was the top of the remaining Upper Haystack tree, where these birds used to perch a lot. It also did in fact still contain about 250 holes at the top, which contained about 80 acorns. 13 February 1115. Watching. 1120. Starting to rain. 1130. Several here getting acorns: (1)♂yel-Blk #390, (2)♂OrR#307, (3)♀wn-Blk/nn #170. (4)♀Lg/M #391. (5)♂DBRW #309. 1315. Leaving. The above 5 birds were around several times during the period. I have no idea what's up with the other 2. (The ub♀ has always been hard to see, but ♂236 has always been rather easy, even without his wingstreamer. Both could be off somewhere else, I suppose. ♂170 has been doing most of the defense of the granary, chasing Titmice, etc.) 15 February 1745. I flushed 3 birds (and there were probably more) from a hitherto unknown hole low in the '75 nest tree. 24 February 1045. Watching. 1050. ♂80rRw #307 have to displace a Titmouse. 1100. Now (2)♀Lg/M#391. (3)♂wn-DB/#170. 1125. (4)♂DBRW #309. 1135. Leaving. Too cold today. Still no sign of ♂236! I declined to count acorns here for the moment, but there are many, and so sign of any significant depletion for the moment.
