No problem -
The Snake River Birds of Prey National Conservation Area (aka SRBOPA) (how's
that for a mouthful!) is managed by what is now known as the USGS Biological
Resources Division; Forest and Rangeland Ecosystem Science Center, Snake
River Field Station. The project that I was referring to was a 5 year study
on the effects of military training on raptors. A lot of good papers and
publications came out of that study, all of which are available through the
Butch Olendorff Memorial Library.

This is a great resource for publications on raptors and there is now an
online database (Raptor Information System, RIS) that allows you to search
through ~29,000 titles! (FMI e-mail <library at eagle.idbsu.edu> or go to
<http://www.ris.idbsu.edu).

As for the keys - here are the citiations and they should be accessible
through the RIS.

I don't have a method for Great-horned owls aging but I would be
learning more about your reference to "Snake River Birds of Prey project
came out with some great pictoral keys for aging Red-tailed Hawks,
Prairie Falcons, American Kestrels, Ferruginous Hawks and Golden
Eagles". Please send me information on this if you don't mind.

thanks,

Hello Tweeters:

Does anyone have a well-tested method of aging, or a reference for an
aging
key, for nestling great-horned owls (those not in-the-hand).

The Snake River Birds of Prey project came out with some great pictoral
keys
for aging Red-tailed Hawks, Prairie Falcons, American Kestrels,
Ferruginous
Hawks and Golden Eagles, but I don't know of any keys for owls. These
are
very useful as nestlings can be approximately aged with the use of a
spotting scope.
