GAP Analysis Predicted Distribution Map

Steller's Jay (Cyanocitta stelleri)

Species Code: CYST

Legend: = Core Habitat = Marginal Habitat Breeding Range Map The green area shows the predicted habitats for breeding only. The habitats were identified using 1991 satellite imagery, Breeding Bird Atlas (BBA), other datasets and experts throughout the state, as part of the Washington Gap Analysis Project. Habitats used during non-breeding months and migratory rest-stops were not mapped.

The Steller's Jay occurs commonly in a variety of forested habitats and open or fragmented landscapes within forested zones, mostly at low to moderate elevations, but breeding into alpine parkland. It can be found in mixed forests, hardwood forests, coniferous forest, residential areas, and agricultural areas in forested landscapes.

Good habitat in core zones included all habitats except high-density development, estuaries, and bare ground below the Mountain Hemlock zone (west side), below the Subalpine Fir zone (east side) and above the steppe zones. Peripherally it occurred in the Mountain Hemlock, Subalpine fir, and Alpine/Parkland zones.

Generally, Steller's Jays occur in conifer forests characteristic of western temperate areas, and Gray Jays occur in forests with more boreal conditions, but there is tremendous overlap between the two species in Washington. Gray Jays tend to be more common than StellerŐs Jays at higher elevations, on north-facing slopes, and in cold, wet forests. The Olympic Peninsula Gray Jays prefer dense wet forests, which are less suitable for StellerŐs Jays. However, StellerŐs Jays now occur at higher elevations and more commonly on the Olympic Peninsula than previously, due to the presence of people. Structures, food, waste, and forest cutting favor StellerŐJays, leaving Gray Jays to inhabit the remaining unaltered coniferous forest.
