Sorry if this is the wrong forum but there's not a birding forum. I see what I believe to be Black Crowned Night Herons feeding nightly along the susquehanna. I posted it here since I'm hoping to get pics of them tonight to confirm this. I was curious as to how rare these birds are? I did locate a rookery of black crowned night herons a few years ago here in lancaster and actually rescued a juvenile that ended up being rehabilitated. (fell from the nest at a VERY young age) I looked at them through binocs and they didn't look like yellow crowned from what I could tell. Unfortunately the binocs were horrible and it was getting pretty dark.
