An iconic hotel in the heart of midtown Manhattan is buzzing with thousands of tiny new visitors. But watch out: They'll sting if you get too close. Honeybees have taken up residence at the Waldorf-Astoria New York, one of New York City's most famous institutions and a favorite stopover for many U.S. presidents. The hotel plans to harvest its own honey and help pollinate plants in the skyscraper-heavy heart of the city, joining a mini beekeeping boom that has taken over hotel rooftops from Paris to Times Square.
