    Abstract: A wind shield supported by a beehive bottom board prevents directly impinging wind from creating high-pressure differences across the beehive such as promote excessive ventilation. By providing an entry path that opens upward and follows a twisted path, proper ventilation and access to the beehive by the bees may be maintained. The wind shield may be quickly installed on a variety of beehive designs and easily removed during warm weather.
