Steller's Jay

Cyanocitta stelleri

Steller's jay is a bird native to western North America and the mountains of Central America, closely related to the blue jay found in eastern North America. It is the only crested jay west of the Rocky Mountains. It is also sometimes colloquially called a "blue jay" in the Pacific Northwest, but is distinct from the blue jay of eastern North America. The species inhabits pine-oak and coniferous forests. Source

Movement and weather

Each season it is first heard regularly where daytime highs are around 17°C (typically 5 to 33°C, from 14 areas). That range is wide, so temperature alone does not explain when it turns up.

Over the weeks it was present in the past year, its centre in North America ranged from 27°N in June to 49°N in April, about 2,400 km apart.

Arrival dates

The week it was first heard regularly in each region, after at least six weeks away. Dates differ from south to north, so a region has a range.
