Only seen for a few seconds. Landed in a tree's branches, and caught a glimpse of its blue body and its prominent black crown. Heard it call several times.
The Steller's jay (Cyanocitta stelleri) is a jay native to western North America, closely related to the blue jay found in the rest of the continent, but with a black head and upper body. It is also known as the long-crested jay, mountain jay, and pine jay. It is the only crested jay west of the Rocky Mountains.
