Barrow's Goldeneye birds fly close to surface of water for some time after the running takeoff typical of diving ducks. Not as gregarious as many other waterfowl. Relatively tame. In western mountains may nest as high as 10,000 feet above sea level.

The forehead rises abruptly from a short triangular bill to a crown that appears flattened, and the nape is puffy. Female bill color varies with season and may be mostly dark with a yellow tip in the winter; the amount of yellow gradually increases to the point the bill may be entirely yellow or have dark.
