This isn't a bird feeder, but it's a camera focussed on a peregrine nest in downtown Manchester, NH. There's nothing going on now, but you can mark the link for next spring if you are into birds of prey.

Here's a whole list of bird webcams, all over the world. I scrolled down and clicked on one in Ossipee, NH, that has info on their camera and system (I think it's a site for a sales rep.) It has at least one site for all of the New England states except MA, plus a bunch for NY.

Here's the page I got on google, and I noticed several that had info on how they built their set up, if that's of interest to you.
