This fall I was watching large flocks in "V's" flying very high. Hard to ID for sure but I thought they could be Trumpeter Swans, not Canada Geese. Their honking just sounded a bit different and the wing beat a bit slower.

Martha's always flipping fern leaves over to examine their spore patterns. It's of how they "propagate"  :o big word  ;D
But doesn't mean I know much more. Martha's into the plants. I'm better at birds, less so trees.
