Seagulls are loud, greedy, invasive, polluting and aggressive. They eat anything that moves and a lot of things that don’t. Hate them if you will, but seagulls are 100% badass. Here are the secrets to their astounding success—a one-stop primer to the wonders of seagull behaviour.
1. Communicate. Loudly.
Oh, I know what you’re thinking. “They screech and they squawk; you call that communicating?” Actually, yes. We may not be sure what they’re saying, but clearly they’ve got something on their minds. Stop and listen next time, and try to note down what you hear. It’ll be a call note or a long call, or a choke call, or an anxiety call, or a mew, a head toss, a copulation call (would that be a booty call?), an attack call or a departure call.
I’ve recently learned to recognize the alarm call. It’s a lot like their other calls, but there’s a certain urgency to it. Hear the call, look up, see a bald eagle. Every time. It’s pretty cool.
And I can personally attest to the uniqueness of the copulation call. I witnessed it all spring- it kind of goes ew-ew-ew-ew-ew-ew-ew. Once you learn it, you’ll recognize it a mile away. Follow it to the source and you’ll see two gulls copulating, guaranteed—followed shortly after by post-copulation calling. It kind of goes, “What, that’s it?”
Gulls are social creatures. Kind of like us, in fact. Most of the time, they act like they can’t stand each other. They squabble, they posture, they fight, they eat each other’s eggs… but deep down, they know they need each other.
There’s an understanding among gulls, an uneasy peace that’s built on a strict code of status and seniority. The top gulls, usually the most mature, are likely to get the best real estate at the centre of the colony. That way, when the predators come by to do their plundering, the poor lower-status saps get eaten first.
But here’s the thing: with all that tension and rivalry, they know when to band together. When the eagles attack, or the foxes charge in, a disciplined white air force takes wing, diving, screeching, and shite-bombing all intruders like a well-oiled machine. Shock and awe.
So cooperate. Remember who your friends are. And don’t forget, when things get tough, you can always eat the neighbour’s children.
I once knew a veterinarian who worked a lot with endangered species. She said that every species on the brink of extinction had a damn good reason for being there: they’re fussy feeders, they freeze to death in a stiff breeze, they only breed every third new moon of a leap year, and so on.
Gulls, on the other hand, are easy to please. Here in Vancouver, back in the day, our gulls would only nest on certain rocky islands offshore. Pricey real estate, as you can imagine, if you’re a gull. So around 1970 or so, they decided to branch out. The early adopters, the hipsters of the gull world if you will, moved to the mainland. Suddenly everybody had to do it, and their breeding success skyrocketed. Not long after, another gull pioneer had the bright idea of nesting on our flat apartment rooftops, which are basically artificial islands, just as secure as the old-school rocky ones. Dumb like a fox, these birds.
I used to work at the Vancouver Aquarium, and got to hang out with the marine mammal trainers a lot. They used to work so hard with their whales and dolphins, patiently training them, encouraging them, rewarding them with herring, squid, and more herring. The reinforcement schedule was basically 1:1—a reward for every behaviour completed successfully. That’s a high-maintenance program.
But meanwhile, lurking behind the trainers, were the glaucous-winged gulls. Waiting. For hours, they would hang back, hungry, biding their time. “Soon… soon,” their hungry eyes would say. And sure enough, sooner or later, the trainer would have a careless moment, and bang! The gull would lunge in for the fish. Sometimes it didn’t work. Sometimes the trainer would close the fish bucket in the bird’s face. Sometimes the trainer would smack the gull with a target pole.
Didn’t matter; they’d just wait for the moment to come around again. Seriously, the reinforcement schedule for that behaviour must have been 1:543 and still they persevered. And eventually, they got their fish. I once watched a gull snatch a fish out of the steely jaws of a 1600-pound rutting male Steller sea lion. I swear it did a victory lap around the entire facility.
5. Use your hidden talents.
Gulls have at least two superpowers. First, they can drink saltwater. Think about it: water, water everywhere, but when you’re a seabird, what are you going to drink? Well, seagulls just drink the ocean, and are able to pump the salt out through a gland at the base of their bill. Very few animals can do that: seabirds, crocodiles, sharks, and sea turtles. That’s gangsta, son.
And, despite their reputations as walking garbage dumps, they have one amazing power of discernment: they can sense paralytic shellfish poisoning before it’s too late. Within five minutes of eating a bad clam, they puke it up... and won’t touch that species of clam again.
Have you ever seen a snail kite? I didn’t think so. They’re beautiful birds, but picky eaters. They patrol the everglades of the southern US in search of apple snails, which are pretty much their only food source. When the apple snails decline, so do the snail kites. Bummer.
But gulls? Pretty much anything, anywhere, anytime. If it breathes, grows or moves, or did so recently, it’s dinner. Wild gulls, in wild areas, eat mussels, clams, gooseneck barnacles, fish and other birds’ eggs. But here in the city, they’re basically eating french fries and Cheetos. Their catholic food tastes (that’s small-c catholic, though the image of them eating communion wafers actually amuses me a little more than it should) are the single biggest reason for their incredible success.
7. Just do it.
If there’s one thing gulls do well, besides eating garbage, it’s making babies. They’re actually remarkably attentive parents, with both Mom and Dad doting on their two or three chicks for months before they’re independent. I got to witness this first-hand this year: two pairs nested on the rooftops across our alley. Cute. Educational. Charming. But holy baby Jesus, the noise.
And they are committed. With some of the less-successful species, you look at them the wrong way and the entire breeding season is a write-off. With whooping cranes, for instance, everything needs to be perfect, and I mean absolutely perfect or they just can’t. Humidity a little off? Bad weather? Too many flies? It’s over. Don’t even talk to them. But gulls? Pffff. A predator can walk into their colony and lay waste to their nests, and they just rebuild. And they’ll do it again, and again… an average of 4.7 times before they finally write it off for lack of time left in the season.
So for god’s sake stop feeding them.
Their high reproductive success, coupled with their incredibly flexible feeding habits, means their populations are skyrocketing. Here on the west coast, we have a 350% increase in gull populations in the last fifty years. And that’s a problem.
When they’re not eating garbage, they’re eating other birds’ eggs. (Sometimes they’re just eating other birds; I know a birder who was watching a gull stand beside a little sandpiper, perfectly peacefully on the shore, and suddenly, GULP. No more sandpiper.) If we don’t stop fuelling their garbage addiction, the problem will only get worse. Many of our seabirds are in trouble; the last thing they need is an artificially-inflated squadron of gulls hunting them down in breeding season.
Please dump your garbage in the dumpster, where it belongs. These supremely well-equipped birds don’t really need any extra help from us, anyway.

Hate them. They nest on my roof and attack me.
I like to see them in a wild habitat , away from garbage, just foraging off the land and sea at low tide. Their squawking is music to my ears as it blends with the crashing surf in wild places. When they are part of the natural environment along the coastal shores they are welcome additions to the landscape. When they are in urban areas begging food and excreting everywhere I have less tolerance for them.
I love gulls and crows. I live in Nanaimo and walk the seawall daily – if it wasn’t for gulls and crows – some days I wouldn’t have any birds to hear and watch.
Gulls are like dandelions. If they weren’t so plentiful we would be astounded by them. Absolutely beautiful when on the wing around the fishing vessels. Riding the currents or almost motionless suspended in the air they are remarkable studies in aerodynamics.
Loved this article! I am from Australia and belong to an irreverent Facebook group that was started during lockdown called #BirdTheFeckAtHome. Over 7,000 species have been seen by the 9k members from their backyards, whether it be a flat in Melbourne or a bird lodge in Ecuador, just as long as it is the place they live. It has provided information, friendship and humour that tided us through those dark days, but will keep going as it is such a great platform for birders worldwide. We have a member who is a scientist and keeps us on the straight and narrow when it come to taxonomy and, in particular, common names. THERE IS NO SUCH THING AS A SEAGULL has become a catch cry for the group, hence the interest in your brilliantly observant article on seagulls! All the best from Australia. Lindsay
Hi Lindsay- I love the name of that group. Seagull, however, is a perfectly good word in the English language. Seagulls exist. They’re a thing. They’re just not part of the standardized names of gulls. It’s not incorrect to say you saw a songbird, though there is no species called that, right? Same with gulls. To say there’s no such thing as a seagull is pedantic and a form of gatekeeping by birders against other people who love birds.
Interesting article, but the title literally got me laughing out loud which is uncommon.
I throw my garbage where it belongs, but I like to keep a bit of food on the balcony for finches or crows. The gulls obviously don’t care who the food is for and there was no sign (can they read too?). A gull came and ate some seeds off the plate. Then it stood on the chair and started moving in a way that let me foresee what was coming next, but it was too late to stop it. Splash! The chair was dirty, and by the time I asked that gull to leave it was too late.
If that happens to you, I suggest you hurry to get lots of water to wash it away. It makes cleanup easier.
