I saw this jailbird jay while out walking in Bend. It perched on a rock behind the heavy bars of a fence around the Hayden Homes Amphitheatre.
This is a California Scrub-jay. Here’s a closer look.
In 2016, the American Ornithological Union (AOU) split the Western Scrub-jay into two species, the California Scrub-jay, Aphelocoma californica, and Woodhouse’s Scrub-jay, Aphelocoma woodhouseii. They appear very similar. This post by Andy Birch describes and shows the characteristics of each species.
