The recent high numbers of Short-eared Owls and Northern Harriers at the
Gage Road area in Addison County, I suspect is enhanced by very high
numbers of voles. I haven't been there myself this fall, but I've been
birding/dog-walking in several large cut-hay and stubble corn fields in
western Addison County. The vole signs in places are the highest
density I've seen (to my recollection) in quite a long time. There are
extensive runway systems, holes everywhere, and foxes and fox diggings
are common.
