Many people have asked me: Is it OK to take down an abandoned bird’s nest? Generally, the answer is no. First, in many states it’s illegal to remove a nest, depending on the species of bird and what stage of use it’s in. It’s often hard to know the status for sure; your removal could be breaking the law. For your personal health, a bird’s nest is nothing like a decorative craft store one; it’s often loaded with parasites, bacteria and mites that can be harmful to humans. Even if a nest is absolutely abandoned, birds are notorious recyclers; it’ll get torn apart and the pieces will be used by other birds for new nests.
