Uruk-hai are a crossbreed of Men and Orcs, given an Orc's bloodthirst and strength, and a Man's ability to function during the day, though they hate the sun.

The also look more like Men than other Orcs do, allowing them to pass as goblin-looking Men in Bree and the Shire.

Or that's the theory, anyway.
