Kino Lorber has acquired all U.S. rights to Su Rynard’s songbird documentary “The Messenger” and will begin releasing the film in December.

“The Messenger” chronicles the struggle of songbirds worldwide to survive in turbulent environmental conditions brought about by humans as populations of hundreds of species have declined. The film contends that their demise will signify the crash of the global ecosystem along with the disappearance of honey bees and the melting of the glaciers.

The film will open in New York at Cinema Village on Dec. 4 and in Los Angeles at Laemmle Monica on Dec. 11, followed by a release in over 30 markets nationwide and a subsequent DVD and digital release next year.

Producers are SongbirdSOS Productions Inc. and Films à Cinq/ARTE. “The Messenger” won the prize for Best Conservation Program at the Jackson Hole Wildlife Film Festival.
