Blue Jay

Look for

A large, crested, brilliant blue bird with black-and-white barring on the wings and tail, a white chest, and a black "necklace" across the throat. Big bird, big voice, big personality.

Size: ~11" — robin-sized but thicker and louder, with a striking crest.

Listen for

• Call: a loud, harsh "jaaay! jaaay!" — the sound every Southerner knows.
• "Queedle-queedle": a liquid, musical sound like a tiny squeezebox.
• Hawk mimicry: they imitate Red-shouldered Hawk and Red-tailed Hawk calls with near-perfect accuracy.
• Quiet songs: surprising soft whistles and warbles heard only up close.
• Softer clicks and rattles in family groups.

Where in Memphis

Everywhere with oaks. Backyards, parks, woodlands, feeders. Numbers peak in autumn as thousands of jays move through Memphis caching acorns.

Behavior

• Acorn-cachers. A single Blue Jay may cache 3,000–5,000 acorns per autumn, burying them across a wide territory. Many are never recovered — and many of the oaks in Memphis neighborhoods were planted by Blue Jays. After the last Ice Age, Blue Jays helped oak forests expand northward at up to 400 yards/year — faster than squirrels could have managed.
• Corvid intelligence. Like crows and ravens, Blue Jays are exceptional problem-solvers, use tools in captivity, recognize individual humans, and remember slights for years.
• Hawk-mimic trickery. Jays imitate hawks to clear feeders of competition, or to alarm other birds about real predators. They're working both sides.
• Complicated migration. Some Memphis jays are resident; others migrate from further north. A jay at your feeder in January isn't necessarily the same jay from June.
• Aggressive toward hawks, owls, and cats. They organize mobbing flocks to drive predators off, sounding the alarm for the whole neighborhood.

Story & folklore

The oak planter

This is the best fact about Blue Jays: they built the Eastern hardwood forest. Studies of post-glacial oak range expansion show that squirrels alone couldn't have moved acorns fast enough — jays cache acorns in open ground (ideal germination sites), forget some, and effectively plant them. Every oak-shaded Memphis street is partly a Blue Jay monument.

The devil's bird

Old Southern folk belief held that Blue Jays were absent from human view on Fridays because they were carrying sticks to the devil. Friday absences meant the birds were in hell, reporting on gossip. It's pure folk tale, but variants of it were repeated across the Delta into the 20th century.

"You can always spot a Blue Jay on a Monday, but never on a Friday" (old Tennessee saying)

The Memphis Grizzlies / Tennessee connection

Blue Jays aren't a Memphis mascot, but they're a Southern Baptist sermon staple — "noisy as a jaybird" and "flighty as a jay" turn up in Delta preaching and blues lyrics. They're also a Toronto Blue Jays MLB export — though that bird on the logo is a stylized version of the species found all over Memphis.

The "jaywalker" probably-folk-etymology

"Jaywalker" (a pedestrian crossing recklessly) may come from the old American slang "jay" meaning a rube or country fool — which in turn may trace back to the loud, brash Blue Jay. Etymologists argue about this, but the bird is definitely the source of the insult "jay."

Fun facts

• Blue Jays are in the corvid family — relatives of crows, ravens, and magpies. All corvids are unusually intelligent.
• The blue color is (again) structural — crush the feather and it's brown.
• Blue Jays mate for life and recognize each other's voices.
• Young Blue Jays are fed by parents for up to 2 months — long for a songbird.
• They sometimes "ant" themselves — rubbing live ants through their feathers, likely to spread formic acid as a parasite-killer.
• A Blue Jay can carry 2–3 acorns at a time — one in the gular pouch, one in the throat, one in the bill.
• The scientific name Cyanocitta cristata means "crested blue chattering bird."
• Oldest known Blue Jay in the wild: ~27 years. Exceptional longevity.
