What does a blue jay symbolize?

The short answer

Most meanings people give the blue jay come straight from how it behaves: it is loud, it stands up to hawks and cats, and it is clever. People read it as a sign to speak up, to protect what is theirs, or to be resourceful. Older folklore in North America is less flattering, and casts the jay as a trickster or a troublemaker.

The jay as trickster

In the Pacific Northwest, Chinook stories collected by the anthropologist Franz Boas and published as Chinook Texts (1894) feature Blue-Jay, a boastful, meddling character who gets into trouble and drags his sister Ioi into it. The bird of those stories is the Steller's Jay, the dark blue crested jay of western forests, not the eastern Blue Jay. The idea of the jay as clever, noisy and not entirely trustworthy runs through other Native American stories too.

Mark Twain turned that reputation into comedy in "Jim Baker's Blue-Jay Yarn", part of A Tramp Abroad (1880), in which a jay spends a day trying to fill a cabin with acorns through a knothole, and its friends come from miles around to laugh at it. Twain's narrator insists a jay has more vocabulary than any other creature and uses more bad grammar.

"Jaybirds go to the devil on Friday"

In the folklore of the American South, recorded among both Black and white communities in the nineteenth and early twentieth centuries, blue jays were said to vanish every Friday to carry sticks or grains of sand down to the devil. A jay seen on a Friday was supposed to be one that had just come back. Joel Chandler Harris refers to the belief in his Uncle Remus stories. It is one of the clearest examples of a bird being given a meaning that has nothing to do with its biology — jays are as easy to see on a Friday as any other day.

What a blue jay is actually doing

Blue jays mob predators. When a jay finds a hawk, owl or cat, it screams, and other jays and smaller birds gather to harass the intruder. That is the protective reputation. They also imitate the calls of Red-shouldered and Red-tailed Hawks, and nobody is entirely sure why; it may warn other jays, or it may scare other birds off food.

Their blue is not a pigment. The feather's structure scatters blue light, which is why a jay feather looks brown if you crush it or see it backlit. Blue jays cache acorns by the thousand in fall, burying them for later, and the ones they forget grow into oaks. Researchers have suggested jays helped oak forests spread north after the last ice age.

Jays can be shy at feeders despite their noise. They like whole peanuts, sunflower seed and corn on a tray or platform, and they will carry off several nuts at once to hide.

The jay as a personal sign

Modern readings tend to be positive: a jay as a sign to be bold, to say what you think, to look after family, or to plan ahead the way a jay caches food for winter. Those are interpretations built from behavior rather than from a single tradition. If a jay keeps appearing, the most likely reason is a source of food nearby, often an oak tree or a feeder with peanuts.

Blue jays in winter and on migration

Blue jays are partly migratory, and that is one of the bird's real mysteries. Every fall, loose flocks of jays move south along the shores of the Great Lakes and the Atlantic coast, and on a good day watchers count thousands passing a single point. Yet many jays stay put all winter, and the same bird may migrate one year and not the next. Researchers who band jays still can't fully explain who goes and why.

For people who feed birds, this means a jay at the feeder in January may be a local resident or a visitor from farther north. Jays are also easiest to see in fall, when they are busy carrying acorns and peanuts away to hide. The Toronto Blue Jays baseball team, founded in 1977, took the name from a bird that is common across southern Ontario all year.
