Tawny Owl (Strix aluco)
Iceland Gull (Larus glaucoides)
Dark eyes and dark wedge dividing the facial disks. Bill pale grey, not yellow like Ural Owl. Plumage rather indiscreet, with colour ranging from grey to rufous brown. Body shape characteristic; tubby and barrel-like, with short tail and short rounded wings. Flight with characteristic frequent glides on arched wings.
Sound:Song a resonant descending "hoooooo". After 2-3 sec. typically followed by a slightly ascending, vibrating "hohohohohoho" and quickly another descending "hooooooo". Complete phrase: "hoooooo, hohohohohoho-hoooooo". May omit parts. Other often heard sounds; a sharp, short, disyllabic "kiu-wik". First syllable ascending then descending, and last ascending in pitch.

CCAll 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.
