Buffalo (or more accurately, bison or cattle) and cowbirds have a symbiotic relationship because both species benefit from the interaction, though the balance can be a bit one-sided. Here's how it works:
Type of Symbiosis: Commensalism (mostly) one benefits, the other is largely unaffected.
Why it happens: Cowbirds feed on insects: As buffalo move through grass, they stir up insects like grasshoppers and flies.
Cowbirds follow and eat: Cowbirds follow the buffalo, eating the insects that get flushed out. This gives them easy access to food.
Buffalo benefit slightly: In some cases, cowbirds may also eat parasites off the buffalo's skin, offering a small grooming service. But this isn’t always the case, so the benefit to the buffalo is minimal or inconsistent.
So, cowbirds rely on large grazing animals like buffalo or cattle to help them find food, and the buffalo usually don’t mind or even slightly benefit. That’s what makes it a (mostly) commensal relationship.
