Description
The pied crow (Corvus albus) is a distinctive crow found across most of sub-Saharan Africa. It is a large crow, approximately 46-50 cm (18-19.7 in) in length, characterized by its contrasting black and white plumage. The upper parts, wings, head, and throat are predominantly black with a metallic sheen, while the neck and underparts are white. Its eyes are dark brown, and it has a strong, black bill. It can be confused with the larger white-necked raven (Corvus albicollis), which has a white neck and thicker bill, but lacks the white on the underparts.
Diet & habitat
The habitat preference of the pied crow is diverse, ranging from savannas and grasslands to urban areas. They are particularly common in areas where human settlements exist, as they are known to exploit the food and nesting opportunities these areas provide. Pied crows are omnivorous and opportunistic feeders. Their diet includes a variety of items like insects, small reptiles, amphibians, other birds’ eggs and nestlings, fruits, grains, and human food waste. They are also known to hunt in pairs or small groups and can exhibit intelligent hunting tactics, such as using tools or working together to distract prey or predators.
Behaviour
Like many corvids, pied crows are known for their remarkable intelligence. They can solve complex problems, use tools, and even recognize themselves in mirrors, a rare ability in the animal kingdom. They are also highly social. Pied crows often form flocks, especially outside the breeding season, and have been observed participating in playful activities, such as sliding down sloping roofs or playing with objects. Additionally, pied crows are capable of mimicking a wide range of sounds, including human voices, which is quite rare for wild bird species.
Nesting
The breeding season of the pied crow varies geographically, but it generally takes place during the dry season. These birds are monogamous, with pairs often remaining together for several years. They build large nests in tall trees or on man-made structures like telephone poles. The nest is constructed using sticks and lined with softer materials like animal fur or grass. The female typically lays 3-5 eggs, which are incubated primarily by her for about 18-19 days. After hatching, both parents feed the chicks, which fledge around 35-42 days after hatching. The young birds may stay with their parents for several months before becoming fully independent.
Status
The pied crow has a large range and a stable population trend. The adaptability of this species to various environments, including urban areas, has helped maintain its population numbers. It is listed as least concern on the IUCN Red List.
