A white parasitic bird that supposedly originated by the sea but is now more commonly found roosting at McDonald's awaiting a discarded french fry or clamoring with its pals in a Taco Bell dumpster; a 'seagull'.

While widely regarded as harmless, these birds are known to be dangerous and attack unsuspecting fast food chain customers in large groups known as "militias".
