I know that because I know the Owner of Wildlife technologies and he has spent millions in filming coyotes and other animals and capturing all types of animal vocalizations from around the world.

He Films in HD and then sells his films to major companies like MGM, Discovery channel and stuff like that.

He has a coyote video out along with a Moose video, there is another coyote video in the works right now. He let me see a teaser of it last time I was at his house, it will be like no other video out.

He also makes the best sounding E-caller available today.
