Abstract
An annual vole (Microtus sp.) index is an important part of Hamerstrom's study of the Northern Harrier (Circus cyaneus) in central Wisconsin (Hamerstrom, F., Auk 96:370-374, 1979). Vole trapping on her study area began in 1964 and 28,911 trap nights have been accumulated by Hamerstrom and her coworkers through 1981. On 4July 1981 I found evidence that a harrier had stolen a trap.
