This may have been mentioned before but I just found the Cornell cams at
www.allaboutbirds.org. They have owls, kestrels, hawks, ospreys, a pond cam and a great feeder cam. My youngest cat loves to watch that one and I've seen Canada geese, blackbirds, blue jays, woodpeckers, goldfinches, doves, and the ever popular squirrels so far! There is a lot of info about all kinds of birds and helps identify birds you may have seen but don't know how to identify. With our falcon season slowing down it's a great place to watch and learn.
