Yooper, there is a catch to that observation. When coyotes are feeding young they need more food so there will be an impact even before the young are ready to hunt. Coyotes bred in Jan and Feb, with a 60-63 day gestation period they could be out of the den by may and June, fawns are easier to catch than adult deer but it takes more of them to provide enough food. The pups won't directly affect the fawn population but they sure do indirectly affect it. In addition, if, as research suggests, when coyotes are pressured by hunting they have larger litters, it would require even more fawns to feed the pups and themselves. Is there a point of diminishing return in the goal of reducing coyotes to save deer? It just may be.
