RE: WoodChucks in Upstate NY
Its Hawks & Coyotes - no doubt.
Also - I think the reduction in cow pastures & hedgerows in farmed fields in my area have reduced the best woodchuck areas. The overall lack of dairy farming in general as well.
Now maybe your area is different - but there were alot more woodchucks when I was young - now it seems I only see them on the road edges, and in rural yards.
Lots more Hawks too - I'd rather see hawks than woodchucks though.
