The Brown Noddy prefers to inhabit tropical and subtropical coastal areas, including islands and coral atolls. In Tanzania, it can be found on the Zanzibar Archipelago, which consists of several islands, including Unguja and Pemba. These islands provide ideal nesting sites for the Brown Noddy, with their rocky cliffs and sandy beaches.

Physical Characteristics of the Brown Noddy

The Brown Noddy is a medium-sized seabird, measuring about 35 centimeters in length. It has a wingspan of approximately 70 centimeters. As mentioned earlier, it has a dark brown body with a white cap on its head. Its beak is yellowish-brown, and its eyes are dark. The Brown Noddy has long, pointed wings and a deeply forked tail, which aids in its agile flight over the open ocean.

Breeding Behavior and Life Cycle of the Brown Noddy

The breeding season for the Brown Noddy in Tanzania typically begins in the early months of the year. During this time, the birds form large colonies on the cliffs and rocky outcrops of the Zanzibar Archipelago. The nests are built close together, often in crevices or on ledges. The female lays a single egg, which is incubated by both parents for about 30 days.

Once the chicks hatch, they are cared for by their parents. The parents take turns feeding the chicks with small fish and squid that they catch in the surrounding waters. The chicks grow rapidly and develop their flight feathers after about six weeks. By the time they are two months old, they are capable of flying and become independent from their parents.
