Great Grey Owl (Strix nebulosa)
Puffin (Fratercula arctica)
Approaching Eagle Owl in size, but shape more elongated, with head being extremely large. Differs from Ural Owl in yellow eyes, concentric markings in facial disks, bold white bars between eyes and black "beard". Wings and tail long. Characteristic pale patch at base of primaries shows in flight, but the species leaves an overall darker impression than Ural Owl. Tail with dark terminal band.
Sound:Song: Cyclic, repetitive, very deep calls rising and falling in volume. Accented start and end of each "hooh". As the call fades away in volume, the speed accelerates. Sometimes disyllabic "ho-ho,ho-ho,ho-ho,ho-ho".

CCAdults in summer at close range unmistakable. Bill in juveniles almost black, and much less deep than in adults. Adults in winter plumage also show much darker bill and cheeks than in summer. At a distance head gives an all dark impression, with characteristic dark "shadow " in front of the eye. Head and bill less elongated than in other auks. Wings rounded with dark undersides. "Thighs" dark. Flight fluttering and energic, with shifting weight and angle.
Sound:Deep, but not so coarse as Razorbill. Smoother and more gliding changes in pitch, like a "slow-motion" laugh or distant chainsaw; "aaaahrrr, aahr, ahr arh".
