It looks like someone may be seeking a solution to the perennial problem of hummingbird-feeder-hogging. If you’ve ever had a feeder like one of these you know what I mean. One feisty hummer claims it and makes it his or her life’s work to chase off any other birds (or insects) that have the audacity to approach. If you’re tired of daytime television it can be quite entertaining.
I don’t know if this works. It might…as long as one pushy hummer tries to claim them all.
