Birdbath Cleaning

  • Why are grackles putting droppings into my birdbath? Is there any way to prevent them from doing this?

    I know it can be a pain to clean out your bird bath over and over again but there really isn’t anything you can do. After their young hatch, grackles keep their nests clean to prevent predators from finding it. Fecal matter from young birds is covered with a sac like membrane which allows them to carry it away from the nest to be disposed of. Birdbaths and swimming pools are attractive disposal sites because the water reduces the smell from fecal matter.
