Stellar’s Jay is most common in forested areas of the Rocky Mountains and Pacific coast. It is bolder than Blue Jay, regularly approaching campsites to steal food. The two species sometimes hybridize where ranges meet.
The subspecies macrolopha (south of the Rockies) has a longer crest and different head markings than birds of the nominate group (Pacific coast, northern Rockies).
VOICE Dozens of vocalizations; foraging birds deliver a raspy, rapid-fire sh-ksh-ksh-ksh-ksh-k and a drawn out descending shhhhhhrrrrrr
