This website is run by the Bird Banding Laboratory where the data base resides. The online information supplied by the observer usually results in an immediate match to the data base where one can learn the origin of the particular bird being reported. Besides that, you can opt to have a certificate of appreciation printed for reporting “your” bird. That and knowing that somewhere you have made a bander happy.
One of the bands will be a numbered aluminum Federal band, whose numbers you probably won’t be able to make out. The colored bands on the other legs, if reported correctly (Left leg white over blue, right leg aluminum over yellow), may result in a match with the data base.

Subject: [Tweeters] Banded Caspian Tern at Discovery Park
A couple of us were birding Discovery Park, Seattle this morning and we spotted a Caspian Tern with leg bands. I don't know who to notify. I've posted a photo of it on eBird. I don't really have a telephoto lens, so it is hard to make the bands out in detail, but they might be clear enough for the person(s) involved in the study. Here's the link: http://ebird.org/ebird/view/checklist/S38477510
It was actually surprisingly birdy there today, considering the time of year and the heat wave. We tallied just over 50 species, including 3 Marbled Murrelets.
