Another consists of a rough, short barking howl. This is a territorial signal, a warning to other coyotes that this country is the domain of a mature male. Still another will open with a female invitation howl--a high, keening wail of a female coyote in heat, announcing her libidinous availability. This should work especially well now, during the breeding season that extends from late January through mid March. We will also use a lost-pup howl, shorter and higher-pitched than adult vocalizations that can often suck in female coyotes. Finally, we have a wounded-pup cry, a tortured yelp that sounds exactly as though you just slammed your own dog's tail in a car door.
