I haven't heard any coyotes since sometime in midwinter here in southwestern New Mexico. Other people are remarking on this too, so I don't think it's usual; does anybody have a plausible explanation? I've heard only one rumor regarding this, that some ranchers have been leaving out food for the coyotes laced with some kind of sterilization drug; and I got that rumor third-hand.
It could just be that this year's babies are still too young to go out hunting, so the mamas are home in the den and only the older males are fetching the food... but would that explain no yelping at all? And the rodent population, especially that of rabbits, seems way larger than usual.
Any insights appreciated -- jc
