Description

The black noddy has a length of , a wingspan of and a weight of . It has dark plumage and a pale crown. There is a small white crescent under each eye and a white spot above. It has long tapering wings and a truncated tail. The sharply pointed bill is black. The feet are fully webbed and are black in most subspecies but orange in ''melanogenys''.

Behaviour

These birds may have become known as "noddies" because of the behaviour of both sexes as they constantly dip their heads during their breeding display. They are very tolerant of humans even to the extent that they can be picked up off the nest. They feed on fish and squid which they gather by flying low over the surface of the sea and picking them up. They may associate with other seabirds in areas where predatory fish are driving small fish to the surface. The nests of these birds consist of a level platform, often created in the branches of trees by a series of dried leaves covered with bird droppings. One egg is laid each season, and nests are re-used in subsequent years. The trees used for this purpose are various but the ''

'' is most often used, and in large trees, there are often several nests. The guano produced by these birds adds large quantities of nutrients to the soil which is of great importance to the plant communities on coral islands.

. At sea it is usually seen close to its breeding colonies within 80 km of shore. Birds return to their colonies, or to other islands, to roost at night.

Cultural significance

This is one of the landfinding birds whose daily foraging flights were traditionally employed by Pacific navigators to locate unseen atolls.
