Pied Crow

Corvus albus
Pied crows inhabit most regions in Africa, certainly thriving in South Africa. Extremely intelligent and opportunistic, they share the jackdaw’s love of shiny things. They also have a special flying ability, with broad wings that enable great powers of flight. They are curious, they are great mimics, and they use tools.

Disrtibution

Pied crows inhabit sub-Saharan Africa to the Cape of Good Hope, Madagascar, the Comoros islands, Zanzibar, Aldabra, Pemba and Fernando Po, living mainly in open country where there are villages and towns nearby. This species does not live in equatorial rainforest.

Habits and lifestyle

Pied crows are very social birds and commonly forage in pairs or small groups, but also gather in large flocks where food is abundant. They sleep in communal roosts in urban parks in large trees with many hundreds of other birds. This bird is known for mobbing bigger birds: small birds of prey up to large vultures. It may itself be mobbed by smaller birds. It will also pirate seabirds for food. This species is generally sedentary within its large range. Some seasonal or local movements occur, depending on the range. Movements have been seen after breeding: adults are probably sedentary, while the young move to new territories. The pied crow, like many crows, makes the typical guttural “kraaak” sound, or short “krow” or deeper “rrawrr”. It also makes a dry rattle “tarrrrrh” or “torrrrrh”. Other sounds are nasal, throaty, hollow and flat, and often there is head-bobbing and movements of the tail at the same time.

Diet and nutrition

Pied crows are omnivorous, and eat numerous invertebrates like insects, spiders and mollusks, as well as small vertebrates including rodents, birds and birds’ eggs, lizards, frogs and fish. Small birds and bats may be caught in flight. These birds also scavenge at rubbish dumps and patrol for roadside kill. They eat plant material such as seeds, roots, fruits, dates, oil palm nuts, rice and potatoes.

Mating habits

Pied crows are monogamous, with pair-bonds probably lasting all their life. Courtship displays are performed at the start of the breeding season. The male struts close to and around the female, fluffing its nape and throat feathers. He also bows while he makes rattling calls. In response, the female performs a submission display, crouching and quivering her wings, which is a typical posture inviting the male to mate with her. The breeding season varies depending on the range and also the rains. These birds are solitary nesters. Both adults construct the nest, a bulky structure built from sticks and roots. Its deep cup becomes lined with mud, dung, wool, grasses, string and other material. Nests are often placed high in a tree fork, a telephone pole a, pylon, or a tall building, and rarely on a cliff ledge. 4-5 eggs are laid from September to November, according to the latitude. Both genders incubate but the female does most of it, over a period of 18-19 days. The parents feed and look after the young, which stay in the nest for about 35-45 days.

Population threats

The Pied crow has an extremely large range, and may be abundant locally. It is not currently threatened.

Population number

According to IUCN, the Pied crow is widespread and common throughout its range but no overall population estimate is available. Currently this species is classified as Least Concern (LC) and its numbers today remain stable.

Ecological niche

Pied crows have both a positive and a negative importance. Due to their varied diet, they can damage gardens and agricultural crops. On the positive side, they also eat carrion, thus helping not only humans, but the entire ecosystem in which they live.

Fun facts for kids

  1. Crows are very smart creatures. For example, they will tap birds’ eggs against a branch to crack them open. They have also been seen dropping nuts so that cars will drive over them, picking up the contents after the shell has been crushed. They have been observed dropping stones to crack open ostrich eggs.
  2. Pied crows follow bush fires to eat insects, and they follow the plough to forage for invertebrates.
  3. Crows are absolutely fearless, especially when chasing golden or bald eagles. They will drop stones, sticks or pinecones onto predators or people.
  4. Crows are also emotional animals, reacting to hunger and invasion with noisy vocalizations. They demonstrate happiness, anger and sadness.
  5. Almost all members of the crow family have been seen using tools. Ravens can learn to speak basic human language.
  6. The crow is considered a song-bird and has an extensive repertoire of melodies. Like humans, the more tuneful the song is, the more soothing are its effects. Some crows have been taught to sing songs from operas.
  7. Crows have excellent memories and are able to hide food in many caches, move it several times, and remember exactly where it is. For its size, a crow has the biggest brains of all birds aside from some parrots. The brain-to-body ratio is the same as that of chimpanzees and is not far from that of a human.
  8. Magpies, nutcrackers and choughs are basically all modified crows.
