Depends on how much competition for food is driving the amount of movement of each individual across space…….Coons that just spend all winter going back and forth short distances to corn feeders to make a living are gonna likely have lower mortality than ones that have to scavenge across large areas to meet their food needs…..Typically with most any specie the more something has to move and the further it has to travel…..the higher the mortality rates are gonna be…..We’re likely propping up much higher coon populations through Feb 11 and then sending that inflated population off onto the landscape to pillage and plunder during the early spring….I would imagine that the higher populations start exploiting other available food sources during this time period….It would only stand to reason that more coons exploiting resources in the spring would equate to more nests being raided.
