#1. Blue Jay Habitat and Range Facts

Blue Jays live in wooded urban and suburban areas. These areas include parks, backyards, and forest edge habitat. Blue Jays are often found near their preferred food sources, which are Oak trees (acorns are a major staple of their diet) and bird feeders.

Blue Jays are permanent residents across the eastern and central United States. Parts of the western population may be migratory. Blue Jays are also found in southern Canada.

The scientific name for a Blue Jay is: Cyanocitta cristata. Cyanocitta is the genus name and derives from the Greek words: 'kyaneos' (meaning blue) and 'kitta'/'kissa' (meaning chattering jay).

There are four subspecies of Blue Jay:

  • Northern Blue Jay (Cyanocitta cristata bromia): Largest of all Blue Jay subspecies. Found from Southern Canada to Northern United States.
  • Coastal Blue Jay (Cyanocitta cristata cristata): Medium sized, most vivid colors. Found from North Carolina down the Atlantic Coast and east into Texas.
  • Western Blue Jay (Cyanocitta cristata cyanotephra): Medium sized. Found from Wyoming and Nebraska to Western Kansas, Oklahoma and Northern Texas
  • Florida Blue Jay (Cyanocitta cristata semplei): Smallest of all Blue Jay subspecies. Only found in Southern Florida
