Remember those endangered piping plovers that captured Chicagoans’ hearts? They’re back — as the stars of the documentary “Monty and Rose,” screening this month during the One Earth Film Festival.

The festival had been scheduled for Aug. 23-24 at Montrose Beach, where a pair of endangered piping plovers established a nest this spring. 

Organizers of Mamby on the Beach want to move the music festival to Montrose Beach, but conservationists are pushing back because of two endangered birds living at the site.
