NEW ORLEANS (AP) — The reward for information leading to the person or people responsible for killing an endangered whooping crane has increased to $10,000, according to wildlife officials in Louisiana.

Donations from various groups doubled a reward offered earlier, according to a news release from the Louisiana Department of Wildlife and Fisheries.

The 1 1/2-year-old crane’s body was found Nov. 15 in a rice and crawfish field in the town of Elton in Jefferson Davis Parish. A necropsy determined that it had been shot that day or the previous day.

A $6,000 reward is also still being offered for information leading to the arrest and conviction of whoever killed a whooping crane in November 2018.

Whooping cranes are among the world’s most endangered birds. The Louisiana wildlife agency and its partners have reintroduced more than 150 into the state since 2011, the release stated.

There are now about 75 birds in Louisiana’s flock, including three that hatched in the wild.
