Hi Everyone,

Saw a strange bird at my pond yesterday. It was the same size of
a woodduck (which is about 3/4 the size of a normal duck), black or VERY
dark blue, had a neck like a goose, and flew into and sat in trees. I'm
thinking it may be a baby herring that hadnt developed it's colors yet. I'm
in western PA zone 5. Any ideas?

A night heron? I have one on my farm pond nesting this year, they do perch in
trees but I usually seem them lurking around the edges in underbrush. Do a
Google search for heron pictures.
BTW...they eat fish.
