This publication explains how to keep woodpeckers from becoming a problem or how to lessen the problem if one currently exists.

Although most people find a few ducks or geese acceptable, waterfowl populations can quickly get out of hand. One pair of geese can, in five to seven years, easily become 50 to 100 birds that foul ponds and damage lawns, golf courses, and crops. This six-page fact sheet provides information on controlling damage caused by Canada geese, ducks, and swans.

The open-water areas and large concentrations of fish at aquaculture facilities appear to be a virtual smorgasbord for wildlife that eat fish, including birds. This six-page fact sheet identifies birds that have caused problems at Pennsylvania facilities and discusses a wide variety of damage control methods. It includes a listing of control materials and suppliers.

Large numbers of birds around barns, livestock and poultry facilities, and farm buildings can cause damage and unsanitary working conditions. This six-page publication explains steps to keep birds from becoming a problem or to lessen the problem if one currently exists.

If you notice house finches at your bird feeder with crusty, watery, or infected-looking eyes, you are not alone. A condition called house finch conjunctivitis, discovered during the winter of 1993–94, is spreading through the eastern United States. Some sick birds recover, while others become blind and die of starvation or fall prey to cats and hawks. This four-page fact sheet discusses how to know if birds at your feeder have the disease, what happens to infected birds, which wild birds are affected, what you can do to prevent spread of the disease, what to do if you find dead birds at your feeder, and other issues.
