The first time I saw a grackle, I mistook it for a crow for a split second. It was only when I noticed its long tail and absolutely furious facial expression that I was like, “Oh.”

While grackles are typically pretty gregarious birds, we have a single male boat-tailed grackle (Quiscalus major) that visits the back yard here. He’s very pretty — black at first blush, but iridescent shades of peacock blue, bronze, and violet when the sun hits just right. Unlike crows, he also has light eyes. (Which, I think, lends to the whole expression thing.)

He’s usually very difficult to get a picture of, since he’s nothing if not wary and easy to startle. Lately, he’s been coming closer to the kitchen window and displaying more curiosity. I thought it might be a good time to write a post dedicated to these beautiful, interesting birds.

Grackle Folklore

Most grackles move in large groups, called “plagues” or “annoyances.” This might seem unfair — worse than a murder of crows, even, or an unkindness of ravens — but it likely comes from their ability to decimate corn harvests. They’ll show up to follow behind plows in order to grab the turned-up worms, insects, and mice that wind up in the furrows (which isn’t really a bad thing, if you’re a farmer) but they’ll also descend on ripe corn to feast on the grain.

Grackles can be a bit of a problem for bird feeders, too. Smaller than crows, they’re quite happy to avoid the work of digging up worms and bugs and instead go for the nice, nutritious seed in a feeder. Where a crow or other, larger bird will ignore things like thistle and millet, grackles will dive right in. This can end up leaving nothing for seed-eating songbirds, so many people aren’t too stoked about seeing a crowd of grackles turn up in their yards.

Nonetheless, these birds have an important role. Unlike many small songbirds, which primarily feed on seeds and don’t dig up burrowing insects, grackles help control pests like invasive grubs and worms. During the time of year when seeds are the most abundant and make up a larger portion of their diet, they also help propagate them in their feces.

Not everyone finds these birds to be nuisances, either. In the late 1400s to early 1500s, the Aztec Emperor Ahuitztol purposefully introduced great-tailed grackles (Quiscalus mexicanus) into the capital Tenochtitlan and the Valley of Mexico. These birds were taken from the Aztec provinces of Totonacapan and Cuextlan in the Totonac and Huastec regions of Mexico, and received plenty of human intervention to help them establish themselves and grow their numbers in their new home. They were well protected and well fed, which allowed their population to take root.
These birds were named teotzanatl, which roughly translates to “divine” or “marvelous grackle.” Certainly a far cry from calling them a plague or annoyance!

(This is far from the only case of something like this happening. Aztec emperors kind of had a thing for bringing in exotic plant and bird species, and even importing special gardening staff to help their new acquisitions thrive.)

Interestingly, these grackles were protected — not only by guards, but also by public shaming. It’s uncertain why this was so necessary, unless attempts to hunt the birds were legitimately an issue. This could have been because they’d become pests, or because their feathers were considered very valuable. Probably both.

Grackles are also the subject of an ancient legend. In it, Zapate the great-tailed grackle was unable to sing. Being a very clever, tricky bird, he stole songs from the sea turtle. This left the turtle without a voice, and the grackle filled with… well, all kinds of noises.

While they aren’t members of the corvid family, they share crow, raven, and magpie’s intelligence. They’re able to solve puzzles, catch fish, and will even clean the grills of cars in order to get at the tasty, tasty smushed bugs.

Grackles also seem to be uniquely equipped to detect the Earth’s magnetic field due to natural deposits of magnetite in their little heads. This may be helpful for navigation and migration.

The Symbolism of Grackles

In general, these birds are said to represent caution, resourcefulness, and community support. Be cautious, however — the appearance of a grackle is also considered a symbol of misfortune.

As with a lot of birds, you often have to pay attention to what they’re doing when you see them since their behavior can color their meaning.

For example, a bunch of grackles can represent friendship, community, and support. A single grackle, not so much.

A grackle foraging or stealing food can be a sign that you need to be resourceful. You may be entering a time when you’ll have to survive by your wits.

These birds also engage in a behavior called “anting.” There, they crouch and spread their wings over anthills. As the tiny insects scurry over them, they pick off mites and release formic acid, which helps repel pests. These birds will also fumigate themselves with everything from stolen moth balls to discarded cigarette butts — whatever keeps the feather mites away.
If you see a grackle anting or fumigating themselves, it may be a sign that it’s time for some reflection, spiritual cleansing, or actual decluttering. You might need to schedule some time to take inventory, clear some of the chaos from yourself or your environment, and make a fresh start.

No matter whether grackles are a welcome sight to you or not, these are brilliant, beautiful birds with a fascinating history. From dumpster scavengers to the protected birds of an imperial house, they have lived closely with humans and fulfilled many roles for ages.
