Gyrfalcon (Falco rusticolus)
Marsh Sandpiper (Tringa stagnatilis)
Largest falcon. Heavily built. Grey upperparts and white, speckled underparts. Juveniles with browner plumage than adults, blue-grey legs and longitudinal streaking below. Diffuse moustache-stripe, and the whole head seems dark at distance, lacking a defined cap. Rounder and broader wings, longer tail and bulky belly distinguishes it from Peregrine. Underside of wings with dark coverts in contrast to pale base of flight-feathers. Extremely powerful, but slower flight action than Peregrine.
Sound:A coarse, drawn out, Peregrine-like "kaaawt", with emphasis on ending, is repeated in series. Much slower paced than in small falcons, and deeper and with different attack than in Peregrine. Also shorter, coarse warning-calls.

Small, but tall and elegant Tringa. Body the size of Wood Sandpiper, but stands as tall as Greenshank. Tibia especially long. The needle-like, straight bill adds to the elegance. Pale face, especially at base of bill. Back grey in adults, with star-shaped speckles in summer and narrow, pale fringes in winter. Immatures with broader fringes and overall darker upperparts. In flight the long legs trails far behind the tail, and the narrow white wedge on the back is conspicuous. Wings are dark with no bars, and shows as the darkest part of the bird also when on ground (especially in adults). Surprisingly quick and easy take-off. Posture generally erect and tall, particularly when nervous.
Sound:Song a slow, melancholic whistle "tu-lee-uu", with the middle part highest in pitch (and with falling glissando). Similar to Spotted Redshank in structure, but with a clear tone (little risk of confusion). Flight call/contact call similar to singular instances of alarm call of Redshank, consisting of a single note rising abruptly in pitch in a split second and then falling; "kieew". Lingers a bit at the ending of the note, giving it a clearer glissando than in Redshank.
