What: Wood frogs (Lithobates sylvaticus) have been singing in Centennial Woods for about a week now (sounds like a bunch of ducks quacking). Yesterday I was out and found several egg masses in various stages of development.
Where: Wood frogs breed in shallow seeps, cattail marshes, and vernal ponds (particularly fond of the latter) and just about anywhere else there aren’t fish to eat their tadpoles.
Other notes: There was a couple of inches of water on top of a thick sheet of ice at the bottom – must have frozen all the way through this winter. The little “pool” of water is at the bottom of a seep and slowly filters into Centennial Brook. The water on top is probably from increased flow of water as frozen ground water has been melting.
