Large-billed Crow

The large-billed crow, also known as the jungle crow, is a remarkably adaptable bird found throughout Asia. Scientifically known as Corvus macrorhynchos, this species is easily identified by its prominent bill. First described by Johann Georg Wagler in 1827, it was initially grouped with the eastern jungle crow and Indian jungle crow as a single species.

There are nine subspecies of the large-billed crow, each with unique features that sometimes lead to their classification as separate species. These crows vary in size and body proportions depending on the region. They typically possess dark greyish plumage with glossy black wings, tails, faces, and throats.

The range of the large-billed crow is extensive, spanning northeastern Asia to Afghanistan, Iran, South and Southeast Asia, and parts of Cambodia. Their habitat preferences are versatile, encompassing woodlands, parks, gardens, and cultivated areas with trees. In the southern parts of their range, they tend to favor open country.

These crows are opportunistic feeders and will consume a wide variety of foods. Their bold behavior, especially in urban areas, can sometimes make them a nuisance, such as when they rip open garbage bags in search of food. For breeding, they build their nests high in trees, lay 3-5 eggs, and take about 35 days to rear their young.

The large-billed crow has a deep, resonant voice with a distinctive call. Despite their adaptability, they face threats from filarial parasites, pathogenic viruses like H5N1, and infections that cause enteritis. Nevertheless, their ability to thrive in diverse habitats and their bold nature make them an important part of the Asian avian ecosystem.
