I love all my backyard birds - even the house sparrows that flock in dozens & empty the feeder I refill in about 20 minutes flat, even when they kind of yell at me when the feeder is empty. recently I bought a bird feeding station kit where I can hang about 4 different feeders, it includes a suet cage and a tray and also a small bird bath. I also got a woodpecker feeder for adding peanuts and sunflower seeds.
The problem was some of the sparrows decided they liked this feed better than their regular mix. It was fine for the most part, but they were aggressive towards the woodpeckers and the nuthatches. The poor downy woodpecker below, tried and tried, but couldn't get a morsel when the sparrows were there.
After a lot of research into sparrow spookers, I settled to make a Magic Halo! Most of the commercially available ones are for keeping away all birds and this is the only thing I found that helps to keep sparrows away from feeders. I used a plastic bowl, drilled a few holes in it and dangled 6 jewelry wires from it. And it really worked like a magic! It's been a few days since I have put this up and the sparrows are sticking to their feeding station. Almost all the other birds - woodpeckers, nuthatches, chickadees and a few red-winged black birds and grackles have been visiting the woodpecker feeder without having to fight with the sparrows! Every once in a while there is an errant sparrow on this feeder, but they hardly stay on.
A blurry photo from inside the kitchen doors to show the sparrows sticking to their station & the ground :) Now I am tempted to get one of these stations for the front yard too!
