OB:BP is a female, banded as a chick at Salinas State Beach in '09.
PR:AA was banded as a chick in '10 at the same location.
OY:RO was banded in 2011 as a chick at Moss Landing Salt Ponds.
I managed to take a LOT of images which I will be posting the best of to my website, but here is one I particularly like. It was the chick that had been banded at Salinas State Beach in 2009:)
