Another thread got me thinking. It is probable, I think, that buck age structure, though overall likely poorer here than in most states, is a bit variable across Michigan. One member postulated that half of the antlered bucks in Michigan are 2.5 years old or older, and I thought that sounded unrealistic in the extreme. jkhillsdale remarked that his opinion is similar to my own.
I went back and checked the logs of my hunts for the past 10 seasons. Based on hunting season observations, over that period, I have seen roughly between seven and eight 1.5 year old bucks for every buck I've seen that was 2.5 years old or older. Put another way, if I see 21 different bucks in a season, 17-18 of 'em will be 1.5 years old.
Now, I understand this is a "sighting" ratio, which would differ from a real census, as older bucks tend to be less visible. Also, field-judging is imprecise, though differentiating between a yearling buck and one that is 2.5 years old or older is generally a breeze. Still, even allowing for these things, I have a tough time believing that yearling bucks do not comprise a bare minimum of 75% of antlered bucks in my area, and likely, a higher proportion than that.
Now, I've also spent a fair amount of time at a high-volume processor in the area, and have also volunteered at check stations in the southern lower a few times, and my observations there have mirrored what I've seen on my farm. Similarly, that would represent a "harvest" ratio, in which yearling bucks would likely be over-represented.
In my hunting area, there simply aren't too many yearling bucks that survive their first hunting season.
Of the antlered bucks in your hunting area, what proportion do you believe are yearlings?
