Alaska Dept of Fish and Game has recently produced a pocket guide with color photos, drawings and descriptions to help determine the age of your marten catch. You can classify it as a juvenile or adult. It folds out to be small poster size to hang on the wall for quick reference. You can also print your own version from this link to their web page American marten Click the link at bottom to download PDF

For people outside of Alaska, the measurements used may not apply to their area!!

Got one in the mail yesterday.

White? Barb? A little help, here?

I contacted Alopex and told her the link does not work. If she cant fix it I'll have her email the material to me and I'll post an active link

Give this link a try for a PDF version.

Thanks guys!

I fixed the link. Herk Eng's link is directly to the PDF, mine is to the ADFG web site where you can then download the pdf.

Glad someone called them what they really are.
A 'pine marten' lives in Europe, not North American and is just one of the 8 species, world wide.

That's interesting!
