Subject: [NHBirds] Determining age of Great Gray Owls
There is a webpage that gives some good information on aging and variation
of Great Gray Owls. It includes comparative photographs and talks about
melanism and related things. One thing of note is:

To age them, a scope is essential. [But] If you are taking photos of
perched birds to determine age, the best photos are of the sides and the
back, showing the wingtips, secondaries, wing coverts and tail. At the bottom of the page is a link to
the homepage.

I thought the bird in Newport looked darker than the one I saw in Durham a
few years back.
