I was excited when I first saw it--a mystery foot (small raptor?), and banded. I should be able to track this down!
But after a little research I realized that what I needed was the standard aluminum band that every banded bird receives, the one with the information on it. The Ontario Field Ornithologists link page has a bunch of links to sites that deal with banding. The two biggies are the USGS page and Environment Canada's Bird Banding Office.
I think what we have here is a colour code of some kind, keyed to the species and research purpose for which this bird was banded. The standard band must have been on the other leg--now probably in the scat or other casting of a turkey vulture, coyote, fox....whoever.
The rule in the photograph is marked in centimetres. I am hoping that if I can identify the species, I might be able to track the research purpose from that.
The foot has four toes, three forward, one back. There is a claw on each (one has broken off).
The nail itself is about a centimetre long. The middle forward toe is 3 centimetres, the side toes, 2 centimetres and the backward facing toe, 1.5 centimetres (all measurements not including the nail).
So that's it--a colour code and a foot, both out of context. Please leave a comment if either means anything to you--or if you have an idea about how I could track this further.
