Coyote Rescued From Cholla Cactus

The red wolf is thought by some researchers to be in fact a wolf/coyote hybrid rather than a unique species. Strong evidence for hybridization was found through genetic testing, which showed red wolves have only 5% of their alleles unique from either gray wolves or coyotes. Genetic distance calculations have indicated red wolves are intermediate between coyotes and gray wolves, and they bear great similarity to wolf/coyote hybrids in southern Quebec and Minnesota. Analyses of mitochondrial DNA showed the existing red wolf populations are predominantly coyote in origin.
• Communication
The calls a coyote makes are high-pitched and variously described as howls, yips, yelps, and barks. These calls may be a long rising and falling note (a howl) or a series of short notes (yips). These calls are most often heard at dusk or night, but may sometimes be heard in the day, even in the middle of the day. Although these calls are made throughout the year, they are most common during the spring mating season and in the fall when the pups leave their families to establish new territories. When a coyote calls its pack together, it howls at one high note. When the pack is together, it howls higher and higher, and then it will yip and yelp and also do a yi-yi sound, very shrill, with the howl.
