Index of Subjects 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. Yt, Dave Webster Kentville START OF PASTE/////////////// 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.

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. <SNIP> Andrew Steeves Wolfville, NS END OF PASTE/////////////// ----- Original Message ----- From: "Gary Murray" <garymurray@ns.sympatico.ca> To: "nature ns" <naturens@chebucto.ns.ca> Sent: Wednesday, October 17, 2012 6:26 PM Subject: [NatureNS] Ruffed Grouse drumming > > Hi all, > > I heard a Ruffed Grouse drumming this afternoon whilst out for a stroll in > the woods near home.
