Reproduction in the coyote is a very delicate process, as females are completely infertile for ten months out of the year, and males are sterile for eight.  The process begins with several males vying for the attention of a single female.  However, unlike in many other species, they do this passively; they linger near her for up to several weeks until the female makes her choice for a mate.  After she chooses, a complex duet of howls between the two ensues, announcing this new bond to any other coyotes within range.  Coyotes appear to mate for life, though this is difficult to confirm in wild populations.

Although six to eight pups are born, only about two survive until theMiller, L.  (image).  <>.
