Appearance:

Very large tern, with deep, dagger-like, blood-red bill with dark tip. Large, black cap reaching well below the eyes. Grey upperparts and white underparts. Rather short tail. Outer primaries distinctly darker than the rest of upperwing, and outer underwing almost black. Unmistakable from the size alone, and leaves a gull-like impression, lacking the elegance of smaller terns. Immatures with paler bill and white forehead (as in adult winter), and markedly speckled back. Hovers and dives. Often rests on the surface, feeding like a gull.

Sound:

Easily recognized by its very harsh calls. Sometimes likened to the sound of a plate of steel being dragged across a concrete floor. Similar in harshness to Grey Heron, but more drawn, with an accented middle; "Kraaeeet", or with a double syllable start "ka-ha-kraaaeet". Immature birds begs with a penetrating, sharp whistle.

Appearance:

Similar to Great Spottet Woodpecker, D. major in all plumages, but can be separated by the following fieldmarks: Moustache stripe does not connect to the black neck like in D. major, but this is often difficult to observe. Note also that young D. major may have similar (but smaller) gap. Tail almost black with just small white spots at edges of base (bold black and white edges in D. major). Nostril coverts white. Vent more pinkish than red, while red neck patch of male reaches further towards the crown. Immature birds may recall Middle Spotted Woodpecker, but note black border between crown and cheeks and long, powerful bill (like Great Spotted). Chest of immature often with pink wash.

Sound:

Contact call similar to D. major, but softer and not unlike alarm call of Redshank. Drumming also similar to D. major but longer (especially in males) and with marked lowering of volume at the end (diminuendo).
