Medora, N.D. (AP) Theodore Roosevelt National Park is inviting volunteers to participate in the annual nationwide Audubon Christmas Bird Count.
The count in its 115th year is the world's longest-running citizen science event. Information gathered helps scientists learn more about how birds are faring throughout North America.
Birders should bring their own binoculars, field guides and warm clothing.
The area to be covered encompasses a 7 1/2-mile radius around Medora. More than 65 different species have been sighted during previous counts in the area.
Interested volunteers for the Medora area count should gather at 8 a.m. Saturday at the south unit visitor center.
