Where to see them

Did you know…

  • It breeds on floating nests anchored to water plants.

    From Black Tern

  • It is the only European tern that is almost black in breeding plumage, a striking contrast with its white and grey relatives.

    From Black Tern

  • It does not plunge-dive like the sea terns: it works the surface of the water in light flight, picking insects off it, a feeding style closer to that of a swallow.

    From Black Tern

  • Its nest is a floating platform of plant matter anchored to the aquatic vegetation: it rises and falls with the water level, a solution that lets it breed in wetlands of shifting level where a fixed nest would be drowned.

    From Whiskered Tern

  • It hunts without submerging: it works the surface of the water in slow flight, picking off insects and fry, a style very different from the plunge-diving of other terns.
