Distribution and Habitat
The white-breasted cormorant has a wide distribution throughout Sub-Saharan Africa, inhabiting both coastal and inland regions. It can be found along the Atlantic coast, ranging from Morocco to Guinea, and along the east coast from Angola to the Cape of Good Hope. Additionally, it is present in the vicinity of the Red Sea.
While this waterbird is adaptable to various environments, it is more commonly found in freshwater habitats in the eastern and southern regions of Africa. Freshwater rivers, dams, and other bodies of water serve as the preferred habitats for the white-breasted cormorant. These areas provide abundant food sources and suitable nesting sites.
The white-breasted cormorant is known to form breeding colonies, with significant nesting sites identified in Djoudj National Park in Senegal. These colonies provide a communal setting for the birds to raise their young, fostering social interactions and offering protection against predators.
In addition to its established distribution and habitat preferences, the white-breasted cormorant exhibits migratory behavior. Some populations are known to undertake seasonal movements, with individuals from northern and western regions of Africa migrating to more temperate and southern parts of the continent. These migratory patterns contribute to the species’ long-distance dispersal and allow for resource optimization.

Behavior
The white-breasted cormorant is known for its unique behavior. One of the most distinctive behaviors observed in these birds is their habit of standing with their wings outstretched. They do this to dry their plumage, which tends to get waterlogged when they swim and dive. This behavior not only helps them regulate their body temperature but also serves as a signal to other cormorants.
This species is also known for its vocalizations. They make various sounds, including calls and squawks, which are often used for communication and territorial purposes. These vocalizations play an important role in the social interactions and hierarchy within cormorant colonies.
During the growth stages, the white-breasted cormorant undergoes a breeding season. During this time, the colors on their head become more intense, serving as a visual signal of their reproductive readiness. The ability to fly and dive underwater is also a notable behavior of these birds. They are skilled flyers and can soar through the air with agility. In addition, they are excellent divers and can plunge into the water to catch fish.
In terms of diet, the white-breasted cormorant primarily feeds on fish. They are opportunistic feeders, taking advantage of fish-rich marine environments. Their hunting techniques involve diving into the water, chasing after fish, and catching them with their hooked bills. This species plays an important role in maintaining the ecological balance of their habitats through their feeding habits.
When it comes to reproduction, the white-breasted cormorant breeds in colonies and lays eggs. However, the exact number of eggs laid and the incubation time may vary and are not specified in the available factual data. Nonetheless, their reproductive behavior is crucial for the continuation of their species and has been studied by researchers to better understand their population dynamics.
