When setting up your feeders, try to keep them about 10 feet away from the cover of shrubs or a brush pile. Cats hunting birds may hide in cover that is too close to feeders. If you have heavy competition from squirrels, try putting up a separate feeder with whole ears of corn for squirrels. Baffles can also be purchased to discourage squirrels from getting into feeders. Aim the feeders so that the birds will not be flying into the windows of your home.
Birds can die as the result of window collisions.
If you have this problem, look at the window from the bird's view to see of there is a reflection on the window, or if another window on the other side of the house gives the illusion of a passage way. To reduce the transparent appearance of the window, you can try attaching paper or cardboard to the inside of the window. Commercial hawk silhouettes can work if you use several. If reflections are the problem, you will need to change the window's appearance by putting something on the outside such as strips of paper, ribbons, or mobiles. Another solution for window collisions is putting netting over the outside of windows.
