If caught feeding on these animals or on large livestock, the opportunistic prairie wolf most likely took advantage of an already dead animal. Coyote females may be courted by several males but choose only one mate. Pups are born with eyes and ears closed and without the ability to regulate their body temperature. Eyes open in about two weeks, ears in about three weeks, and temperature regulation improves from birth. Pups stay with Mom and Dad for several weeks, learning to hunt successfully before trotting off to fend for themselves.
Infant mortality is high.
Distemper takes its toll, as does human predation. Heavy roundworm infestations can also kill pups. Some youngsters may be killed by older pairs or by resident packs if they trespass on occupied territory. Coyotes are very vocal. Their yips, barks, and howls pierce backcountry skies and are more and more often heard in suburbia as their range extends even to residential backyards and New York City's Central Park.
