Melanerpes formicivorus
1800 Hastings Reservation
12 February 1500. Counted stores: 1046. This doesn't include about
95 acorns in one of the dead limbs which fell since the
last count. This limb had about 200 holes (possibly 250)
and was actually one of the larger sets of storage holes
here up until its demise. I moved it over to the
fallen limb above the granary and put it up off
the ground so the birds may reclaim some of the
acorns remaining in it.
Other minor but worthy-of-note details: 1) I noticed
a new hole in a dead limb about 40' up over in the side
of the tree away from most of the stores. It looked like
a good candidate for roosting or a nest. It didn't
look easy to open. The limb is only 6" or so in diameter
and is permeated with fungus. 2) The 1500 birds are
still using the old nest tree here at will (see 1500 notes).
Also, while I was counting stores, I saw a bird fly from
the hillside up above the granary (toward LHay)
directly to 1500 (!). I have no reason to believe that
this group isn't still doing fine, however; they do have
a goodly number of stores stashed away here.
1520. On my way back to 1500 I saw a bird fly from 1500
over to the old dead roost tree over by Horsetail.
Whichever it was was immediately displaced by one of the
3 birds that were there (presumably the whole group).
30 March Ron reported birds here flying in and out of the nest
hole in the granary, so we went up and checked the hole
with the mirror. But, as suspected, nothing yet!
