You can only tell if a bird is hatch year or after hatch year based on physical appearance. It takes some time to properly identify the correct characteristics. I know the feathers of the tail can work earlier in the season but after that, during the bulk of the hunting, it gets much more difficult. I learned this last year in one of my college classes and I am no pro, nor do I want to give out descriptions of the features being that I am not sure of the age identification myself. I will go look for my old papaers I kept from last year to get a more precise answer.

Ok so one way to tell HY or AHY is to look at the tertial feathers that are located nearest to the body when the wing is outstretched. If they are rounded and wide, it is an adult male bird but birds can always lose feathers and replace them so it is never certain. If the 4 outermost primary coverts have a buffy edge that can help to identify an immature bird. For the tail feathers, look at the tip and if the feather continues to the end, it can be AHY but again, I learned these when we went to band ducks in September of last year so my memory is a little sketchy.

A good HSOforum to use for a guide of age, sex, and species.

There is no easy way. Fresh feathers every year. I was lucky enough to get to work on a Stellars Eider banding project in Izembek NWR in the 90's. We recovered unreadable aluminum bands where the numbers were impossible to read. They were able to come up with the band id through acid etching. That was pretty neat. One of the biologists was working on trying to age birds through measurements but never heard what came of this. Certainly, the 15 year banded birds were in no easy way different from the others.

    • The past week has had me having multiple close calls and missing a brute at 45 yards.  Tonight I talked my dad to give it another try and there were birds in the field when we got there.  Birds ended up leaving as we tried to sneak in.  A short 20 minutes later they were back and we watched and worked the big group of toms and hens for more than 2 hours before we got one to commit.  Dad shot him with his 20 gauge at 48 yards,(this thing shoots an awesome pattern).  The 3 year old was down and only flopped a few times.   Nice 1+ inch spurs, 10" beard and heavy.  A good evening for sure!
    • Sorry to disappoint guys, but this tom was not my first bird of the season. Apparently that's part of the rules. The score won't count towards the team. I don't have any measurements for the jake I shot so we will have a zero from me.    At least my freezer is full. 
    • Way to  go 1957 !! Congrats!!
    • sugar is not a drug. 
    • Another good day today out on Superior ,,,, Had my first double and triple in the new rig today ,,, the day didnt start out with perfect weather but the fishing more then made up for it ,,, The mud  covers a lot of water but fishing the tea  colored water and edges of the mud paid off ,,, the cohos grew 5 inches  from eating this years smelt,,,, had some go 23 inches today 
    • Say no to drugs, like sugar.  Yes, sugar is a drug.
    • I won't be able to post the scores for this week until maybe Wed. so if someone else wishes to do so feel free to do it. In fact for the entire summer season I'm going to be pretty much hit and miss. So don't count on me the lake is calling and I have no computer there. My scores will drop like a rock unless luck prevails.
    • That should make things interesting
