1977 Walter D. Koenig
Melanerpes formicivorus
Bianca Hastings Reservation
15 January Counted stores and took acorn samples:
Woonkoll: 408 (35)
Main tree: 208 (65)* The entire primary storage limb
from the '76 nest hole up has fallen with a loss of the
remaining acorns (600+) and 1500-2000 holes. Remember
that they just lost 1000+ holes from another limb here in
winter 74-75. Very interesting.
"New area": 273
Blue Oaks: 182
Old tree: 188
25 January Saw 8140 when I came over to look at the downed limbs
again. I can see no evidence that the acorns are being
removed; i.e. that the birds are reclaiming them at all.
Also, it looks as though no good roost/nest holes were lost (except
for the 1976/7? hole which was split in two).
