Here is a re-post of information on blue Corvids. The Corvidae family of birds also include crows, ravens, nutcrackers, and magpies. Information listed clockwise from photo.

Blue Jays are found mostly in the eastern two/thirds of the United States and southern parts of Canada, among oak and pine wooded areas, home gardens and feeders.  Blue Jays are a crested jay with distinct white spots on wings and tail, along with a black necklace. They are noisy with harsh and musical sounds, like most others of the Corvidae family. They are also known to mimic Red-Shouldered and Red-Tailed Hawks.

Pinyon Jays are found in arid Pinyon-Juniper forest areas, as well as yellow pine wood areas in the western U.S. Their distinct markings are a short tail, spiked bill, and blue all over. They are very social birds, rarely seen solo. They feed on mostly Pinyon pine seeds.

Western scrub jays are found in the western United States and Mexico. They are common among Pinyon-Juniper and Pine-Oak forests, brush and shrubs in desert, canyon, and mountain foothill areas. They prefer brush to forest terrain. They will eat insects and spiders in the summer, berries and seeds in the winter. Scrub jays really enjoy acorns, if available, they will bury them for later consumption, which contributes to revived oak forests. They are like many in the jay family and can be loud while away from the nest.

Stellar’s are crested with dark heads, blue bodies and bright blue patterned wings, they are the only jay with a crest. The inland form have white stripes near the forehead and eye. They are harsh, loud, and distinct with their voices, you usually know when they are around. The Stellar’s are amazing imitators of squirrels, dogs, and mechanical objects. They can be found in coniferous forests and coastal areas. I see these birds deep in the woods, near pond areas, even in my yard once in a while.
