Blue Jay (Cyanocitta cristata) Invasion of Cascadia

The Cascadia Bioregion, including Montana, Idaho, Oregon, Washington, and British Columbia, is outside of the historical range of the Blue Jay (Cyanocitta cristata), but they have been increasingly sighted in the region since the first one was sighted in Montana in 1958.

I am blown away by this map of recent Blue Jay sightings in the west. In 10 years we're going to have so many Steller's/Blue Jay hybrids. pic.twitter.com/D8kuDQflCx
