If you have been finding dead birds in your pond that probably means it was attacked in the air and fell into your pond, so look out for big birds looking for food.

Birds play an important part in the ecosystem in a pond community, particularly ducks. Birds eat insects and fish. Ducks are a group of birds. Ducks are pond creatures. They enjoy water and are good swimmers. Ducks use ponds to hunt and raise their young. Ducks also mate in ponds. Many people enjoy watching ducks as well and use them as decoration birds and beautifying a natural setting. Most people who have ducks as pets have a pond to keep them.
Three types of forest populations that could not survive in a pond ecosystem are monkeys, ants, and birds.
How do you want to get rid of them? If your pond has fish that you enjoy, or if garden birds and other animals are in the area, I advise you are better to keep the cranes there. Otherwise, don't taint the water by trying to kill the birds with poison and the such.
