Melanerpes formicivorus
(8 August)
1857. #261 probing inside the bark/wood interface of the dead Black
locust at the barn, inserting his tongue numerous times in
this area a particular spot without tapping with his bill. 3 times he seemed to pull something
quite small out, which he then apparently stored in a nearby
round storage hole which necessitated moving 3-4 inches over
to his left. After reaching and inserting his bill in this hole, he
would return to the crevice to continue probing some more, often
turning his head up to 90° in order to gain a better angle. The
third time he moved over to the storage hole, however, he worked at
it a few seconds longer than previously and pulled out what appeared
to be part of an old stored acorn, which he quickly moved up the
limb with and began to drill at.
1910. Nobody else as yet. Leaving.
830. Noticed that the rotten limb where they nested this year
has broken off at the location along three through the hole itself,
probably after the rain and during the storms of a few weeks ago.
The birds themselves were apparently in the valley on the side of
School Hill.
3 September

and picking green acorns. #16 was seen along with one of the

Disappeared about 24 June ± 2 wks.
