I have a 40-50 foot oak tree in my backyard that has become the home for HUNDREDS of sparrows. I have a large circle of bird droppings under the tree and on the roof of my house killing the grass and making things look generally gross.
For some reason, my neighbors and local police frown on the use of firearms or other loud sounds to scare them away. Besides, other than the fact it’s interesting to see a huge cloud of birds erupt from the tree, it’s temporary.
I’ve thought about putting hawk or snake decoys up to scare them off. Does this work? Does anybody have any ideas on how to keep the bird population to a minimum in my tree?
