Here’s an old and spectacular favourite from El Hombre y La Tierra series by Félix Rodríguez de la Fuente. The golden eagle has actually been trained to pull/knock animals off crags. I don’t think it’s fair to be too critical as it follows the standards of nature films of the time, when filming was incredibly expensive and they didn’t have the benefit of today’s remarkable equipment. The scene was filmed in a private estate in Segura y Cazorla. The unfortunate animal is, I believe, a mouflon. The rest, too quick footed for the eagle, are Spanish ibexes (cabras monteses). Read commentary on the forum where it was first posted, and where Clive suggests this behaviour occurs in the wild in Grazalema.
