Blue Jays and peanuts

Blue Jays are always being called mean or aggressive, some folks don't like them....but if you really think about it, they are a pretty cool bird. Here's how I see them. In a ground feeder I put out peanuts in the shell for them. What a Jay will do is fly down, pick up a peanut, shake it, put it down an pick up another. They are searching for the heaviest peanut and then takes off with it. Jays will cache their food. They are highly intelligent and are problem solvers. So as you see there is more to this bird then meets the eye.....
