Melanerpes formicivorus
Pump Hastings Reservation
3 February 1310. Walking up I saw ♀ M/08-18#432 in the Willow forest.
Despite this hopeful observation, a climb up into the tree
revealed that no stored acorns remain - all have been
pecked open (many shells remain in place) and eaten. This
even includes the acorns in the 2 small limbs I'd just placed
a few feet off the ground in the remains of the willow!
Apparently I can be hopeful that the group is still here,
however, at least for the moment.
1610. On the way back ♂ M/or#430 was sitting in the area.
They're hanging in there after all!
4 February 1400. I put 70 acorns up in holes in the Valley Oak here.
I had just flushed a color-banded bird from there, who may or may
not have been one of the 3 birds living here.
8 February Added another 72 acorns. A few were left from the 4th; the
others had all clearly been consumed by pecking woodpeckers.
13 February Added about 65 peanuts (raw) and 10 acorns. Saw no birds,
but there were once again practically no remains from the
last provisioning.
15 February A ♀ is sitting over near the granary here.
21 February Added 40 peanuts. The prior batch has been cleared out
quite thoroughly.
24 February 1010. ♂ M/DB-light#432 sitting in the Valley Oak granary.
1200. Gave these birds 102 more peanuts, which they
seem to avidly consume.
4 March 1630. Flushed one bird here on this amazingly wet day as I
came down and gave them 150 more peanuts.
11 March 1600. Added another 100 peanuts (all others were gone!) No AW
seen.
