Hi Jim & All, Mar 23, 2012
Further to your question about stomping by turtles I have pasted a =
2008 e-mail
START OF PASTE
All, Feb 17, 2008
I vaguely recall having mentioned this previously in some context,=20
but in the early 1970's while preparing sidewalls of soil pits for=20
mapping of apple roots we noticed that scraping the sidewall with the=20
edge of a small mason's trowel to smooth the surface stimulated=20
earthworms to emerge from the sidewall. This applied especially to rigid =
(shatters under pressure but slakes in water) or compact soil.
I now notice that making use of this response is called grunting=20
(Nat. Hist. 8-13, Aug, 1989). In northern Florida, earthworms are=20
collected for bait by driving a wooden stake into the ground and rasping =
against it with a notched stick or old car coil spring. The vibrations=20
induce the earthworms to emerge from the soil surface.
This is all old news but even older news to Wood Turtles in central=20
Pennsylvania & New Jersey who stomp their fore feet to induce earthworm=20
emergence (& stomping by Wood Turtles has been observed in Michigan and=20
Wisconsin). Gulls and Plovers in Europe catch earthworms in damp meadows =
by tramping rapidly with both feet alternately or by vibrating one foot=20
against the ground.
One Robin or one Ruffed Grouse can make an astonishing of noise in=20
dry leaves which leads me to wonder if this and the gait of robins are=20
also forms of grunting for earthworms.
And do out Wood turtles stomp ?
Yours truly, Dave Webster, Kentville
END OF PASTE
I don't recall where I read about wood turtles, plovers & gulls =
stomping but perhaps in the grunting article.

Subject: [NatureNS] re woodcock steps -- was Woodcock sighted this =
morning
A week or two ago, some of you might recall, associated with an =
Internet story someone had sent, was a clickable photo of a woodcock =
that provided access to a short video of a living woodcock on the =
ground, and, indeed when it moved, its steps were very weird and =
syncopated like the way that chameleons (real ones) move very slowly, =
putting up a foot and then rhythmically rocking back and forth before =
putting that foot down, then another very slow and deliberate step, and =
so on.
I have never seen this in the wild, but I have heard people's =
descriptions of the way woodcocks seem to rock back and forth on the =
ground. I even recall someone suggesting this is part of the foraging =
technique, to stimulate earthworms below the surface into upward =
activity.
Finally, I believe that wood turtles also have a stomping or rocking =
motion with their legs that may help with access to underground =
earthworms too?
Anyone out there know something about this??
Cheers from Jim in Wolfville

Forgot to add, I had to go on the NS Museum of Natural History site =
to
correctly identify the bird....nice website!

On my way to work this morning, a bird caught my eye on the edge of =
our
gravel road....it seemed to be moving funny, like it was hurt or
something, so I turned around and drove back, and it hadn't really =
moved.
It's back was to me, and it kept shyly "peeking" over it's shoulder =
at me,
then finally got up the nerve to head into the brush at the edge of =
the
wooded area. It was a pretty cool looking bird, albeit a bit clumsy =
I
thought. I had never seen one before. Wish I had my camera with =
me, I
would have gotten some nice pics!
