Appearance:

Large Tringa with upcurved bill. The mainly white and pale grey plumage (and head) gives it a pale appearance. Upper parts speckled in black in summer plumage. Upper side of wings rather dark, back lighter grey with conspicuous long white wedge. Tail white, with diffuse grey barring. Back of juveniles with v-shaped scales/fringes. Legs greenish to grey-green. Wing beats quite deep and sometimes with "slow motion" like quality.

Sound:

Most heard is a characteristic, trisyllabic "tew-tew-tew" (sometimes two or four syllables). Can resemble redshank, but pitch more stable, and not falling notably. Each syllable is clearly separated and equally emphasized. Song a clear disyllabic "cloo-eeee", repeated in cycles but each phrase clearly separated. At close range a short creaky sound is audible (between each phrase). Redshank may sing in a slightly similar way, but in continuous, linked phrases.

Appearance:

All black swift with small white throat patch. Very difficult to separate from Pallid swift and Plain Swift. Pallid Swift; brownish plumage tone (best seen against darker background), bigger throat-patch than swift, scale pattern on body more prominent, wing-tips slightly rounded, "saddle" darker than wings, and more contrast between darker outer primaries and inner. Plain Swift; throat patch smaller and more diffuse than swift, wings and body more slender, tail noticeably deeper forked.

Sound:

A shrilling trill "zreeeee" of about 1 -2 seconds length, gradually rising in pitch with accentuated firs half, then falling from the middle of phrase. Often continued with a dry lower pitched "trrrrrr" before calling again. Very vocal at breeding area, and often a flock will call together. Despite being quite similar to Pallid Swift, the call is probably the best field character to separate the two. Pallid puts the stress on the ending of the call, followed by a quick fall in pitch (dynamics like moaning with a quick release). Plain Swift calls similar to Common Swift, but differs in slightly fluctuating pitch during the call, and a loss of resonance towards the ending (thinner sounding).
