U.S. Customs and Border Protection has a problem with vultures — specifically, roughly 300 of them that are defecating and urinating all over a radio tower that the agency needs to communicate.

The excretion is coating the entire 320-foot tower in southern Texas, including the interior part that workers need to touch, according to a request for information that the agency sent to vendors. The government is seeking a “Vulture Deterrence Netting System” to be installed in August before the birds’ roosting season.

The migratory birds have been making themselves comfortable on the tower in Kingsville — about 45 miles southwest of Corpus Christi — for more than six years, a CBP spokesperson told Quartz, which first reported on the vultures. CBP did not answer questions from The Washington Post on Friday.
