There are areas of NY state that were loaded with chucks back in the 70's and 80's that are very nearly devoid of them now. Other areas are still loaded with them. I don't know what caused it but it ain't coyotes as there are just as many or more yotes in the areas that are still full of chucks as the areas where they're nearly extinct. It isn't a lack of good habitat either as there are still plenty of good hay/alfafa fields in the devoid areas. I think I remember you saying you used to shoot chucks in Schoharie and Delaware Counties and So did I. I agree they aren't there in huntable numbers anymore. You need to go North a bit to find them now. The farmlands of central NY from Cortland to Syracuse still has good numbers.
