Beobachtungsdetails

A returning individual from last year, confirmed by iris pattern and mirrors on p9 different in each wing. Best guess was and is a California Gull with Herring Gull influence, with recent hybrid ancestry made more likely by mix of colors in orbital ring and pale-speckled iris. Noting that iris, leg color, and wingtip pattern are basically identical to last year, supporting that these features are not likely to be influenced by immaturity.
