Appearance:

Summer: Black throat framed in fine white stripes at the sides, and a chequered black back. Winter: More contrast between dark and white parts than in Red-Throated Diver. Marked transition between dark neck and white front, and the dark grey crown extends below the eye. In all plumages: Heavier neck and bill than Red-Throated, and bill usually held straight. Visibly protruding chest when swimming. Head shape sometimes squarish. Usually shows big white flank patch.

Sound:

Song: a strong, very resonant, full bodied, low whistling with most syllables rising in pitch: "co clooo-eee, co clooo-eee, co clooo-eee". Also a short grunting "karr".

Appearance:

An energetic, small tringa wader. Most similar to Green Sandpiper. Differs by light underwings, larger white spots on back, diffuse border between speckled chest and white belly, narrower dark markings on tail and a supercilium that reaches behind eye. Plumage leaves an overall much paler impression than Green Sandpiper, particularly in flight.

Sound:

Totally different from Green Sandpiper. Flight call a soft, but explosive "whiff whiff" , sometimes with only one syllable. Display call similar to redshank but with only two accented beats; a fast melodious "dee-loo", repeated in cycles.
