Seagulls live at … well, sea. They also roam far and wide and get to some dizzying heights.
So when they gather, on mass, on the sea in a safe harbour, not flying anywhere, just bobbing around, often in the marina or just outside, gathered in a circle like a knitting club……. They know something you might not.
The Wind is coming and relatively soon, even if it’s completely calm now, it won’t be for long.
They know, they’re probably been out there and felt it or seen it building from upon high.
