Hi Gary & All, Oct 17, 2012
I don't know about chances but the part that interests me is ability of
a relatively small bird to cause lateral vibrations in an entire and
relatively massive tree (see following two examples and now three).
I suspect this means that, by control of the pecking stroke timing &
deceleration, much of the energy that would otherwise lead to brain damage
is harmlessly conveyed to the tree by resonance.

Hi Andrew & All, Dec 7, 2008
A year or several ago (all based on memory) I had a similar experience;
placed one hand against a Poplar trunk to steady myself while looking up to
locate the Woodpecker and felt the vibration in my hand. It was a Downy and
a fair sized tree; ~25 cm DBH.

SATURDAY MORNING — LITTLE RIVER FALLS
<snip>
I leaned back against a battered spruce tree. When I did, the pecking I
was hearing with my ears also vibrated in my shoulder. Huh? My woodpecker
was in the very tree I was leaning against.
