When we stopped for lunch on our Green River hike, a jay kept squawking at us from a Ponderosa pine tree. At first we thought he was a Gray (camp robber) jay, since those are known for hanging out around people, begging for food.
We baited him with a few crumbs (gee, can you believe there's yet another critter who wants our measly PBJ sandwiches?), and he cautiously flitted down, eventually gobbling up the treat. He was much more circumspect than the Gray Jays we have met. A closer look identified him as a Steller's Jay. Here are better looks at his bright feathers:
Also known as the Long-crested Jay, Mountain Jay, and Pine Jay, it is the only crested jay west of the Rocky Mountains. A Steller's Jay raises its crest as a threat display, or for showing off to attract a mate. Like all jays, the Steller's Jay has numerous and variable calls. Its alarm call is a harsh nasal "wah". It also imitates the cry of the Red-tailed Hawk and Red-shouldered Hawk. This tends to run off the competition at prospective feeding areas.
