Appearance:

Largest rail in VP. Clearly bigger than coot, and almost twice the size of Moorhen. Generally unmistakable with its dark, violet blue plumage, long, robust legs and heavy bill. Under tail coverts white. Red frontal shield and bill, pinkish red legs. Immature birds with duller coloured legs, duller plumage and faintly greyish/whitish underparts. Trailing legs obvious in flight. Swims readily.

Sound:

Rich repertiore and very vocal. Sounds range from soft, mewing and laughing to hard, extremely shrill trills. Generally louder, and shriller than congeners. Often merges into, or starts with diagnostic, extremely hard trill "krrrrriiit".

Appearance:

Differs from Common Tern in shorter head, and blood-red bill. Legs shorter, but tail streamers longer (extends well past wings in sitting birds). Underparts of primaries with sharply bordered dark trailing edge (diffusely bordered in Common Tern). Both primaries and secondaries transparent to sunlight. Crest less apparent than in Common Tern and underside greyer. Cheeks white just below the black cap, often in contrast to grey lower cheeks. Juveniles lacks buff coloured back.

Sound:

Similar to Common Tern but higher pitched. Typical call a series of high pitched "tip-tip-tip", and longer, ringing, high-pitched "kriiiiii" calls. The drawn out "kree-aaahh" call falls less distinctly in pitch than Common Tern.
