Works just as advertised. Sparrows hop all around it but don’t come in. Chickadees and finches feed as usual, but without the hassle of fighting with obnoxious sparrows. Rabbits soon clipped two of the hanging monofilament lines but fine wire replacements work just as well. Highly recommended.

Normally during the fall, winter and spring I have about 40 House Sparrows living in the bushes near my bird feeder and they tend to eat most of the bird seed and scare off prettier birds - I have even seen them eat safflower seed when no other choice is given. I installed the halo above my new Brome Squirrel Buster tube feeder 6 days ago and have yet to see a single House Sparrow feed from that feeder even though I have seen two House Sparrows on the ground in my yard! - so the halo alone does work!
