Effect of Prey on Predator: Voles and Harriers
Abstract Nesting of Harriers (Circus cyaneus) in central Wisconsin was strongly linked to vole (Microtus pennsylvanicus) abundance during 3 of 4 peak yr within a 16-yr period. Heavy application of DDT on the study area was believed to be the cause of the damped response to one vole high.
