walked yesterday at Great Meadows

Here are a few photos:

Turtle, Mound (nest), Snake (look closely), Frog, and can anyone tell us if those are Grebes in the last picture?   [Update: Thanks to an alert commenter those aren't Grebes, but are American Coots.  Here is the Wikipedia entry to further confirm: http://en.wikipedia.org/wiki/American_Coot - Thanks AlanB]
