features
The white cap noddi, like all other noddis, has gray to sooty-black plumage with a sharply defined silvery-white cap. However, its plumage is slightly darker than that of the other two Anous species. The tail is wedge-shaped with a slightly tapered central control feather (tail feather) and there are small white markings on the lowered eyelid .
The maximum body length is 37 cm, the wingspan up to 76 cm.
behavior
Brooding
White-capped noddis breed in colonies in trees or shrubs. They lay their only egg in a self-made nest made of grass, roots and guano (sea bird droppings). The breeding season is between September and December.
Hunting / food
White-capped noddis hunt only during the day, from early morning until just before dusk.
The food mainly consists of fish , which the noddis grab from the surface of the water . However, they also grab small aquatic animals from the surf near the coast. They fly very quickly and with great agility.
voice
The white cap noddi harshly shouts "Kir" or rattles "Chor". A screeching “Krik-rik-rik” can sometimes be heard in flight.

- Blaunoddi ( Procelsterna cerulea ),
- Graunoddi ( Procelsterna albivitta ).
