Careful what you call a cackler. The West coast boys get pretty upset when anything east of the Rockies thats a small goose is called a cackler. Honestly, we dont have any true cacklers. Hutchies, richardsons, ect but no true cacklers. As for the MVP population I dont know, I am a dump husker but I will say that the last few years with warm weather we are holding a ton of little birds compared to honkers.
