I thought I was one of the best squirrel feeders. We live very near a park that is full of squirrels and I've been feeding some of them for years. Usually when they see me coming, there is a mob scene and it gets pretty hairy. These are the fattest squirrels you've ever seen. One female that I started feeding a couple years ago when she had babies will take the peanuts from my fingers and she is very gentle about it. The rest of them cannot be trusted and you had better have food ready, because they will climb your leg, or jump at you. Even the fattest ones can jump about six feet straight up.
The park is also full of crows and they also like being fed, but they are not quite as brave as the squirrels. Some of them will get within about eight feet of you. They follow me around the park. I don't think these park crows ever leave the park--there's probably fifty of them. There are also a few bald eagles that spend a lot of time at the top of the tallest fir trees. It's quite a society as the crows act as alarms for the squirrels when the eagles, or hawks start circling and looking for lunch.
