There are a few things you can do to clean bird poop if you see it on your property. First, try to get as close to the bird as possible and try to catch the poop in a cloth or a paper cup. If that is not possible, try using a vacuum cleaner with the hose attachment and sucking the poop out of the bird’s mouth. Finally, if all of these methods are not successful, you may need to call a professional to clean your property for you.
