You see a loud, smart, black bird, hanging around with his gang of mates, giving you fearless looks, and constantly rummaging through the garbage (or your picnic) for a snack.
Must be a crow, right? Or at least a corvid relation?
But no, the grackle isn’t even distantly related to the crow. It’s a member of the Blackbird family, which includes the Brewer’s and Red-winged Blackbirds that we see in the Pacific Northwest, as well as Cowbirds and Orioles.
We went to Mexico last winter and as soon as we got out of the airport I started noticing these cheeky, opportunistic birds.
They seemed to be everywhere, always with a beady yellow eye to the main chance.
In the absence of any crows, the grackles began to occupy the part of my brain that is usually filled with corvid observations.
The grackles we saw in Mexico were of the Great Tailed variety (Quiscalus Mexicanus). Locally, they’re called Zanates.
In comparison to crows, they’re a lot more streamlined, with light gold-coloured eyes, and legs that go on forever. The males have a long, impressive (some might say, “great”) tails, and a have vivid blue and violet sheen to their feathers.
The females are much, much smaller (about half the size), with more modest tails and dullish brown feathers.

They’re so different that it took me a while to realize that they’re the same species — I thought for a long time that they were two kinds of grackle that just liked to hang out together.

We did see a dazzling variety of birds in Mexico (pelicans, spoonbills, herons, parrots, hummingbirds, chachalacas, caciques, woodpeckers, buntings, doves, cormorants …) but, for some reason the grackles kept calling to me. I guess I just can’t resist a bird that looks me right in the camera lens and dares me to press the shutter.
Buzz off, paparazzi!
Look out, make way for the Great Tail.
Like crows, the grackles could be pretty raucous. Here’s one making some sort of statement in the early morning near our hotel. Luckily we were up early anyway, on the search for the elusive red cardinal that paid a fleeting and tantalizing visit on the first day, never to be see again. But that’s an entirely different story.

Once I got home to Vancouver I planned to do some more research and write a blog about the grackles, but, what with one thing and another, the cheeky grackles slipped my mind and that mental space got recolonized by corvids.
Luckily I was reminded about grackles last week when I got an email from a friend who’s in Mexico now. She was wondering about the crow-like black birds she was seeing everywhere …
My interest rekindled, I started going through my photos from last year and doing a little more research. I’d looked up Great Tailed Grackles online when we were in Mexico —enough to identify them and glean a few facts — but our internet was a bit dodgy, and there were other distractions of course, so I didn’t get too far.

My recent online search for grackle facts turned up news of a fascinating study by Corina Logan of Cambridge University. The Great-Tailed Grackles she encountered in Costa Rica reminded her of crows, and spurred her to wonder if they shared any of that famous corvid intelligence. In 2016, at the university of California, she performed some tests to find out. A series of food acquisition challenges she set for them proved that, like crows, they were very good at deploying a variety of solutions to solve different problems. This particular skill is known, in bird scientist lingo, as “behavioural flexibility” and understanding it is an important piece in solving the bird intelligence puzzle.
Famous crow expert, John Marzluff, commented on the study, saying that Logan’s study “ clearly demonstrated variability that different individuals have when it comes to learning. That’s really cool. You’d see the same thing in people.”
So crows and grackles, apart from the casually observed similarities, also share a special avian ingenuity. I don’t know if they overlap in any territory and, if so, I wonder if they compete, or use their street smarts to divide up the neighbourhood like avian gangs.
Does anyone reading this live in a place where Great Tailed Grackles and crows both reside?
UPDATE: For an answer to the above question, see Crow vs Grackle.
With brains like ours, the sky’s the limit.
If you’d like to keep reading about grackles, I found an very entertaining article by John Nova Lomax entitled Eight Reasons Why Grackles Are Awesome, published by Texas Monthly. His attitude to grackles reminds me of mine towards crows here in Vancouver.
Postscript
I did see one member of the corvid family when we were in Mexico. The Urraca or White Throated Magpie Jay was sometimes to be found on our early morning bird watching walks. An impossibly exotic looking bird, with a “fascinator” head adornment, it would not have looked out of place at a royal tea party. I’d have liked to spend more time with this bird, but it was a lot harder to spot than the ubiquitous, and always entertaining, Grackle.
