Description
The white-necked raven (Corvus albicollis) is a large bird, notably smaller than the common raven (Corvus corax), with a body length of about 50-54 cm (19.7-21.3 in). This raven is native to Eastern and Southern Africa, its range extends from Kenya and Uganda in the north to South Africa in the south. It is characterized by its white neck patch, shorter tail, and a more robust, arched bill compared to other raven species. The bird’s plumage is predominantly black with a purplish or bluish iridescence. It can be confused with the somewhat smaller pied crow (Corvus albus), which also has a white neck. The pied crow also has a white belly, and a slender and more typical crow-like bill.
Diet & habitat
Habitats of the white-necked raven include open woods, mountainous regions, and cliffs. They are often seen around human settlements, taking advantage of food scraps and waste. This raven is an opportunistic feeder, known for its varied diet that includes insects, small mammals, fruits, grains, and carrion. They are also known to prey on the eggs and young of other birds. This species exhibits intelligence in foraging, often using tools and demonstrating problem-solving skills. These birds also display complex social behaviors, including cooperation among members of a group and the ability to learn from others. They have been observed playing ‘games’ with other species, showcasing their understanding of social interactions.
Nesting
The breeding season of the white-necked raven varies geographically but generally occurs during the local dry season. These birds are known to form monogamous pairs. Their nests are typically built on cliffs or high trees and are made of sticks lined with softer materials. The female lays between 3 to 6 eggs, and the incubation period lasts about 20 to 25 days. Fledging occurs approximately 35 to 42 days after hatching, with both parents involved in feeding and caring for the young.
Status
The white-necked raven is widespread, common and adaptable, but its numbers are believed to be decreasing. Climate change, because of its affinity to high altitude environments, as well as habitat alteration and human interference could pose risks. It is currently listed as least concern on the IUCN Red List.
