We don't have an early teal season in California, so I actually have no clue what it looks like.
But I do know how to find where all the action is: All you have to do is look at band recoveries, so I did just that, just for funsies, because I'm an OCD Dutch Virgo data nerd.
The map below is all the banded teal recovered by hunters in September of 2014 (data for 2015 isn't yet available). The color coding is really complex: Blue dots are blue-winged teal, green dots are green-wings and red dots are cinnamons. Click on the dot and you can see how old the bird was and where it was banded - you can even click through to its banding location.
One caveat: Sometimes the map will show birds being shot in weird locations, or in places where they shouldn't be shot, as in not in season. Keep in mind that all recovery information is reported by humans who might be confused about what they're reporting (the USGS Bird Banding Laboratory wants to know where you shot the bird, not where you live), imprecise (I've seen banded birds allegedly shot at busy urban intersections), or merely cagey ("I ain't putting no X on no stinkin' map!").
But imperfect as it is, it's still fun stuff. Enjoy!
