    Why aren’t you removing the cowbird egg so the phoebe’s can survive? The Cornell website advises that you can. I remove them whenever they are in my phoebe’s nest.

  • Holly Faulkner says:

    Hi Jennifer,
    Because cowbirds are native to the U.S., they are protected under the Migratory Bird Treaty Act and in most instances it is unlawful to use lethal control without a permit, including the removal of their eggs from a nest. However, unpermitted control of cowbirds is occasionally permissible under special circumstances outlined in the Migratory Bird Treaty Act. We recommend contacting your local wildlife authorities if you have questions.
