If they are wild birds, keep the dog food INSIDE. they should not bother the pool, though.
Take away any food
Fishing line is not a humane way to keep birds away from areas a person would like to restrict. The fishing line can kill the bird.
One way to keep bees away from picnic food is by putting out bee traps around the area. Keep food covered and put away food right away.
Tinting the glass won't help, but you can get hawk silouette decals to stick on, and that will usually keep birds away.
A model of a cat may intimidate birds. A real cat would be even better.
Birds make nests so they can keep their babies safe. Also to have a home to stay away from predators. (which would be carnivores like hawks, voltures or other animals that eat birds.)
Check the local hardware store for a plastic owl. This will keep birds away. No poison too.
Many birds fit that description. Most birds will chase away rivals, but a few are especially territorial. Northern Mockingbird- Can be very territorial, especially during nesting season. Will chase away birds, squirrels, and humans with hisses. Nuthatches- Mates will keep out other pairs in order to get the most food. Chickadees and Titmice- While small, a flock of these tiny birds will mob against a larger foe and drive it away.
No. Germs are everywhere, therefore it is impossible to keep food away from germs. No matter where you put your food, there will be germs.
12 gauge shotgun? Or less lethally, stay away from them? lol
to use for a home for the eggs and to keep away from predators
Put spikes on the window sill. Just kidding. Try putting food somewhere far away from the window sill. Maybe it will draw the birds away from the sill and towards the food. That might not work. If you are already feeding them, then try stopping. The spikes are a real solution. There are strips of plastic spikes that, when properly installed, the birds will see and will avoid. How the strips will look on the sills is another problem.
