Teal are legal to shoot in the regular season. I tried teal hunting last year and didn't like the crowds, so waited until the first part of the regular season to hunt them. They are counted like any other duck in the bag limit (6/day).
This is from the game and parks website (http://outdoornebraska.ne.gov/hunting/g ... _coots.asp
Daily Bag Limit: Six ducks (May include no more than five mallards (of which no more than two can be hens), three wood ducks, two redheads, two scaup (lesser or greater), one canvasback, and two pintail).
