Lurking Vultures

Strange problem:

Roughly 300 vultures are roosting on a radio tower that federal agents operate in Kingsville, Texas, “nesting on the tower structure on the railings, catwalks, supports, and on rails and conduit throughout,” U.S. Department of Homeland Security officials said in a plea for contractors to submit “vulture deterrence system” ideas.

...“They will often defecate and vomit from their roost onto buildings below that house employees and equipment,” a CBP spokesperson said of the birds’ six-year conquest of the tower, according to Quartz. “There are anecdotes about birds dropping prey from a height of 300 feet, creating a terrifying and dangerous situation for those concerned.”
