Down here in the SW part of Colorado I have seen almost every kind of duck. Some are not as plentiful, but we have tons of Mallards year round. The 3 varieties of Teal, Widgeon, Gadwalls and a few Pintails. All of the divers on the local lakes. Lots of Canadas year round. I have seen a few snows and specs too. If a person works at it, they can get some great waterfowl hunting here.Great shoot, didn’t realize you had that variety of ducks in your flyway there & that early.
