Overview
The Pink-backed Pelican is a bird species with a striking appearance, mainly due to the pinkish hue on its back that gives it its name. It is one of the smaller species of pelicans, but it’s still a large bird, known for its long bill and a large throat pouch used for fishing. Pink-backed Pelicans exhibit fascinating social behaviors, often seen in large groups and displaying coordinated fishing techniques that can be awe-inspiring.
Native to Africa, the Pink-backed Pelican is found in various water bodies, including freshwater lakes, swamps, rivers, and coastal inlets. Although it prefers fresh water, it can adapt to more saline environments if necessary. Despite being a strong flier, the Pink-backed Pelican rarely ventures far from its habitat, which means its distribution remains localized mainly to sub-Saharan Africa and parts of the Arabian Peninsula.
Pink-backed Pelicans are noteworthy for their adaptability to environmental conditions, cooperative hunting strategies, and exciting breeding rituals. However, like many other species, they face threats due to habitat destruction, pollution, and human disturbance. They are a remarkable species and an essential part of the ecosystems in which they inhabit.

Physical Description:
Pink-backed Pelicans are large birds characterized by a long bill with a sizeable gular pouch for catching fish. Adults have a predominantly greyish-white body, with a pinkish hue on their backs and wings that gives them their name. They also feature a white crest on their heads and a yellowish-orange bill, contrasting sharply with the grey and pink of their bodies.
They stand on short, webbed feet, which aids them in swimming and catching fish. Their bodies are aerodynamically shaped, optimized for flying and swimming, and their wings are long and broad, suitable for soaring and gliding over long distances. The plumage of juveniles is browner than that of adults, and they lack the pink coloration they acquire as they mature.

Native Habitat:
Pink-backed Pelicans are native to the wetlands of sub-Saharan Africa and parts of the Arabian Peninsula. They prefer a range of aquatic habitats, including lakes, swamps, rivers, and coastal lagoons. Although they are adaptable to different habitats, they particularly favor shallow freshwater bodies with slow-moving or still water, which are ideal for their fishing technique.
The habitat of these pelicans is characterized by an abundance of vegetation, particularly trees, which are crucial for their nesting sites. Pink-backed Pelicans generally nest in colonies on trees or bushes near water bodies. However, if trees are unavailable, they have been known to nest on the ground or rocky islets.

Diet & Feeding Habits:
Pink-backed Pelicans are piscivorous birds, primarily feeding on fish. They have a fascinating way of procuring their meals; these pelicans often engage in cooperative hunting, forming a semi-circle on the water surface and beating their wings to drive fish towards shallow water, where they scoop them up in their pouches. Their diet is not exclusive to fish, though; they have also been known to eat amphibians and crustaceans when available.
Interestingly, Pink-backed Pelicans often fish in the early morning or late evening when the fish are closer to the surface. Their pouch helps them scoop up the fish and strains out the water before they swallow their catch. The size of the fish they can consume is quite broad, ranging from small fish just a few inches to larger fish about a foot long.
Mating Behavior:
Mating Description:
The mating ritual of Pink-backed Pelicans involves elaborate displays by males to attract females. Males will puff out their throat pouches, toss their heads, and display their wings to attract a mate. The bond is strengthened once a pair is formed through mutual preening and bill touching.
Pink-backed Pelicans nest in colonies, often with several nests in the same tree. Both parents participate in building the nest, which is a large structure made of sticks and lined with softer material. The female typically lays 2-3 eggs, which both parents incubate by tucking them under the webs of their feet. The eggs hatch in about a month, and both parents care for the chicks.

Social Structure Description:
Pink-backed Pelicans are social birds that are often seen in groups. They not only nest in colonies, but they also hunt cooperatively, using synchronized movements to corral fish. This social structure benefits them as it increases their fishing success and protects them from predators.
Within the colony is a clear hierarchy, with dominant birds typically occupying the center of the colony, where survival rates are highest. Young pelicans often form their groups, separate from adults. While they are generally peaceful birds, conflicts can arise over nesting sites or food, typically resolved by displays of aggression rather than physical contact.
Groups:
Population Trend:
The Pink-backed Pelican is widespread throughout its range, but there is no data regarding exact population numbers in the wild. They are locally abundant in many areas, such as the Rift Valley lakes. The population appears to be stable, with no signs of significant decline.
This species has adapted to some human-altered habitats, such as man-made lakes or reservoirs, which may help them maintain their numbers. However, they remain sensitive to environmental changes, especially concerning water quality and the availability of nesting sites.
Population Threats:
Despite their current stable status, Pink-backed Pelicans face several threats. Habitat loss due to wetland drainage, deforestation, and human encroachment is a significant concern. Pollution, mainly plastic pollution, poses a threat as the pelicans can mistake plastic items for food, leading to ingestion that can harm or kill them.
Disturbances caused by human activity can also be detrimental, especially during the breeding season, as they can lead to the abandonment of nests. Overfishing can also negatively affect their food supply. While not commonly targeted for hunting or trade, incidental capture in fishing nets can cause injury or death.
Conservation Efforts:
Despite the threats they face, the Pink-backed Pelican is currently listed as Least Concern on the IUCN Red List due to its wide distribution and seemingly stable population. However, ongoing monitoring and research are crucial to ensure this status does not change.
Conservation efforts for these birds mainly involve habitat preservation and the reduction of human disturbances in nesting areas. There are also initiatives to reduce pollution, especially in and around water bodies. Educating local communities about the importance of these birds and their role in the ecosystem is another essential step toward their conservation.
