Black-billed Magpie Description

Magpies with a black beak are medium-sized birds with a long tail that can account for up to half of their length. Magpies with a black bill weigh between 145 and 210 grams. Black is used on the head, upper breast, back, and tail. On the wings and lower breast, there are big areas of white. Their bills are large and black, as are their legs. At a distance, black-billed magpies are predominantly black and white, but their tail, body, and wings are covered in brilliant iridescent patches ranging from bronze to green. While both sexes have a similar color, females are around 10% less in size than males.

These birds have a length of 17.5-22 in (44-56 cm) and a weight of 187 g (6.6 oz). Their wings could range from 24 in (61 cm).


Like other corvids, black-billed magpies are opportunistic omnivores. They frequently graze on the ground, and their diet may be inferred in part from the little pellets they vomit shortly after feeding. They feed mostly on insects and their larvae, as well as songbird eggs and hatchlings. Additionally, they consume fruit and grain crops, as well as small animals like mice and meadow voles. Black-billed magpies forage for carrion and are frequently spotted eating at roadkill and human garbage along roadsides. To store food, black-billed magpies create little depressions in the ground or snow.


Black-billed magpies like rangeland and forested areas with open fields, which are typically located near bodies of water. Foraging requires wooded habitats and shrubby thickets for nesting and as a method of escape if chased, whilst meadows and clearings are utilized for foraging. The other habitat requirement is robust trees and bushes capable of supporting their quite large nests. These requirements are typically satisfied in riparian and edge habitats. These same characteristics apply to farmland and agricultural areas, which make rural human populations an appropriate home. Scavenging chances exist in agricultural regions as well, such as open compost piles.


Black-billed magpies have a strutting stride and regularly hop before taking flight. Horizontal flight is often characterized by slow, constant wing beats, but descending flight is characterized by a brief sequence of wing flaps interspersed with pauses during which the wings are tucked tightly to the body. This alternating rhythm results in an evocative J-shaped flight path.
