A good dome protector for my Birdscapes long glass hummingbird feeder was needed so I thought I'd try this baffler. It is wider than the Hummzinger Humbrella and covers the long glass type feeders more than sufficiently from the rain, and it gives the hummers extra protection as well.
Since we don't have squirrels, there is no need to remove the plastic center of the cup (where the two hooks are placed) as stated in the instructions. If the center portion is removed, it causes the dome to tilt such that the squirrels lose their balance. With the center intact, the baffler is sturdy and helps prevent the feeder from rocking too much during windy days. We have hummers that winter here and this baffler is the answer to our long glass feeder needs.
Nothing outside of a battle tank is "squirrel proof", but this pivoting baffle keeps most squirrels off my feeders and lets me see the birds better. I use it on top of my feeders to stymie the "jumpers". When they land on it, it swivels down and they slide off while being kept away from the feeder by the size of the baffle. The birds seem to like that the baffle also keeps them and the feeder dry during rain.
