A Louisiana man was sentenced to probation Friday for killing one of the state's oldest whooping cranes .
Gilvin P. Aucoin Jr., of Ville Platte, shot the endangered whooping crane in July 2018 in Evangeline Parish.
In a hearing before U.S. Magistrate Judge Carol B. Whitehurst, Aucoin changed his plea to guilty for a misdemeanor violation of the International Migratory Bird Treaty Act.
