THE large-billed crow (Corvus macrorhynchos), with a glossy black plumage, has a robust body and a notably large bill, which sets it apart from other crow species. Measuring 50 centimeters long with a wingspan of around 1 meter, these birds are impressive as they glide through the skies of Shenzhen.

These adaptable birds can thrive in various habitats, including forests, woodlands, and urban areas, including parks and gardens near human settlements. This adaptability allows them to find different food sources and suitable nesting sites.

A resident species, it establishes territories within its preferred habitats and remains there throughout the year, taking advantage of Shenzhen’s favorable climate.

Large-billed crows have an omnivorous diet, consuming a wide range of food, but they are primarily scavengers. These opportunistic feeders scavenge for plant matter and small animals. Their diet includes fruits, seeds, grains, insects, small mammals, reptiles, and bird eggs. By consuming such diverse food sources, these crows play a crucial role in maintaining the balance of the local ecosystems.

Their breeding season generally occurs in spring. During this time, they form monogamous pairs and build nests in tall trees or elevated structures. The female lays a clutch of up to six eggs, which both parents incubate for about three weeks. They also care for the hatchlings together. The chicks grow quickly, and within a few weeks, they become independent and leave the nest.
