Appearance:

All white wingtips like Glaucous Gull. Told apart from latter by rounded head, longer wings and shorter, more slender bill. Bill shorter than half the length of head, and lacks prominent hook. Primaries extends well past tail in sitting birds, and the whole rear of the bird seem slimmer. Eye bigger than in Glaucous Gull, with a more "gentle" expression. Comparison with nearby Herring Gulls fruitful. Iceland Gull often smaller than Herring Gull, and less heavy, while Glaucous Gull usually larger. Impression reinforced by Iceland's agile maneuvering.

Sound:

Like Herring Gull, but tone sharper.

Appearance:

A medium sized owl, which can give a very pale impression in flight. Quite similar to a Long-eared Owl with folded tufts, but differs in bright yellow eyes, darker wing-tips and heavily streaked breast in contrast to pale belly.

Sound:

Song: a series of 6-10 deep "ho"s evenly spaced. Much faster than long eared owl, and rising in pitch until the final "ho". Calls: a raspy, drawn, mewing "eeeeeeeeeah" (about 2 seconds), rising in pitch with accented ending.
