The Michigan general season runs through May 31 st and is one of the last seasons open in the country. I have filled my tag on the last day of the season at least four times and two of those were my absolute best birds with inch and a half hooks for spurs. Rob Keck of the NWTF told me that "The late season is your best opportunity to take a mature boss gobbler if you can hold onto your tag that long. A couple weeks earlier birds like that are still henned up and you'll more than likely tag a 2 yr old." Food for thought, and a great reason to stay positive and not be bummed about drawing a late tag.
From my experience, several late season pointers come to mind.
1. With heavier foliage you can get a lot closer to a gobbling roosted bird than earlier in the year. I still don't like to get much inside 100 yards though as you might flush other roosted turkeys. Likewise, because of thicker foliage, a gobbler honoring your calls may be much closer than you think.
2. Early season, turkeys are feeding on seeds, green shoots and whatever they can find. With the late season and warmer temperatures, insects come into play. Freshly plowed fields are prime targets and birds will often head there to feed straight off the roost.
3. Speaking of insects, mosquitos come into play as well. Invest in a Thermacell unit so you can concentrate on hunting, not swatting bugs.
4. With late season comes much warmer weather. Turkey movement slows when temps soar and they tend to loaf in the shade when its hot. My best late season hunting has been early in the morning when it's still cool and birds are active.
5. I haven't noticed anything specific about late season decoying. Decoys are always a hit or miss proposition. I got my gobbler on the final day last year using the Pretty Boy and a couple hens. I did have to wait until the first cutting of the knee high hay so the dekes could be seen along a field edge.
If you think of any other late season questions I'll keep an eye on this thread.
Good late season hunting!
