Just in case you are in a hurry, Texas Parks and Wildlife Department has posted the hunting dates for 2016-2017.
Because spring squirrel season is still open in some counties, the department could not put the dates where it normally does for now. Instead you have to go to http://tpwd.texas.gov/regulations/outdoor-annual/hunting/general-regulations/2016_2017_hunting_seasons if you want to get a head start.
A change to setting migratory season dates in the spring is probably what got the department up and running early. In the past all hunting seasons were closed before dove and waterfowl seasons were set in the summer. That is not the case anymore.
And for those wondering, the general deer season opens Nov. 5 statewide.
