Minnesota just had its first early teal season. By written accounts in a local weekly outdoor column, there was a crap load of violations. And those were only the ones who were caught. There was likely a lot more. Hunters must not have been able to accurately identify teal from wood ducks, which do not yet have full plumage here and are very similar in size. Additionally, the legal shooting hours didn't start until sunrise as opposed to the general waterfowl season which is 30 minutes before sunrise. I presume this was instituted to better help identify teal, which didn't work.
I hope it is not continued next season. We have an early teal season, a youth season, and an early goose season all for a few weeks prior to the general waterfowl season. It sends birds outta here real quick. The governing agency here has catered to specific demographics at the expense of everyone else.
