This picture taken on May 8, 2019, shows two newly born Chacoan peccaries in their enclosure at the Prague zoo, Czech Republic. Prague's zoo says two Chacoan peccaries have been born in the park in May for the first time, a welcome step in efforts to save a species that was once considered long extinct.
