Purchase a model owl or hawk, and put it on display when the neighbor is feeding the birds. You need to purchase a model that suspends, has outspread wings, and, ideally, has a moving head. The hawk should hang from a fixture of your house or from a metal frame and sway naturally in the wind. This will scare off the birds.
Get a cat. Cats naturally prey on birds. The sheer presence of a cat will be enough to scare away most birds.
Install bird spikes along the ridges, posts, roof, and other flat areas of your house. This will discourage birds from landing and congregating around your home, reducing the amount of bird excrement your property receives. Bird spikes don't hurt birds; spikes just make it harder for birds to perch on designated areas.
Things You Will Need
- Model owl or hawk
- Consider trying an ultrasonic sound device designed to repel birds. The sound is inaudible to humans but can be effective in driving away birds. Some devices are more effective than others, so shop carefully.
