A flock of whooping cranes who are being guided by an aircraft on their way to Florida have arrived in Kentucky.
The endangered birds began a migration in early October from a wildlife area in Wisconsin.
A release from the Whooping Crane Eastern Partnership this week says the cranes have entered Union County. It is the 13th group of birds that have been involved in a project that is working to reintroduce the species in eastern North America.
The birds are following two ultralight aircraft on a journey through Illinois, Kentucky, Tennessee, Alabama and Georgia to reach their wintering habitat at St. Marks National Wildlife Refuge in the Gulf Coast.
The birds can be viewed on a live webcam here.
