    You ever watch a seagull at a shore flying in extremely gusty wind? They don’t get credit for being the incredible flyers they are.

    In a cold whipping New England winter wind that abruptly switches directions seagulls manage to gracefully hover over the shoreline, smoothing out all that chaotic energy to methodically comb through the shore wrack from 50 feet in the air.

    When was the last time you actually looked carefully at a seagull wing? It’s just funny to me, seagulls have this identity as the rats of sky but their bodies are basically designed like high speed luxury cars. They might not be the fastest bird, they might not be able to do crazy dives (well they usually don’t anyways), but in terms of high speed handling in challenging conditions they are superbly designed in a way most other birds can’t even remotely compete with.

    Check out this video with slow motion shots of seagulls achieving a stable hover in super gusty winds

    This flight position with the wing “elbows” bent back like this is obviously exploiting a similar thing to swept wing designs in aircraft. Bending their wings like this allows transitioning in a blink of an eye from an extremely high glide straight wing geometry for soaring or arresting a drop from a lull in wind to an extremely aerodynamic high speed wing tuck. Other birds can do either of these things, and adopt similar high speed tucks (especially in dives) but seagulls and other related seabirds are just so incredibly good at using their ability to radically change their wing geometry in split second reactions to create stability out of chaos. It is one thing to be able to soar like a vulture, but to also be able to acrobatically fly in gusty winds around sheer rock cliffs is no small feat even though it is a common sight for many people.

      One time the Canada day fireworks were cancelled because it was too windy, so instead I just watched the seagulls. I swear they were playing in the wind, a bunch were going around a loop, catching the wind and getting carried up over a hill, then looping back around and gliding back to the bottom of the hill to go again. It looked like fun.

      Here’s the thing. You said a “jackdaw is a crow.”

      Is it in the same family? Yes. No one’s arguing that.

      As someone who is a scientist who studies crows, I am telling you, specifically, in science, no one calls jackdaws crows. If you want to be “specific” like you said, then you shouldn’t either. They’re not the same thing.

      If you’re saying “crow family” you’re referring to the taxonomic grouping of Corvidae, which includes things from nutcrackers to blue jays to ravens.

      So your reasoning for calling a jackdaw a crow is because random people “call the black ones crows?” Let’s get grackles and blackbirds in there, then, too.

      Also, calling someone a human or an ape? It’s not one or the other, that’s not how taxonomy works. They’re both. A jackdaw is a jackdaw and a member of the crow family. But that’s not what you said. You said a jackdaw is a crow, which is not true unless you’re okay with calling all members of the crow family crows, which means you’d call blue jays, ravens, and other birds crows, too. Which you said you don’t.

      It’s okay to just admit you’re wrong, you know?

    Malt vinegar is disgusting and ruins fries and the meals of everyone around you because of its smell.

    I’ll die on this hill.
