B. Morphology / Distribution / Habitat Info

Morphology
The Large-billed Crow (Corvus macrorhynchos) is an entirely black bird typically measuring between 45 to 50 cm in length. It is characterized by its glossy, dark black feathers, which often exhibit a purplish or bluish-green sheen when viewed in light. Its most distinguishing feature, which gives the species its name, is its large, thick, and curved bill, granting it the ability to handle a wide variety of food items. It also possesses strong legs for walking and perching. Beyond its physical traits, this crow is noted for its high intelligence, demonstrating capabilities in tool use and complex problem-solving. It is also well-known for its loud, harsh, and often raucous calls (BirdLife International, 2024) 

Distribution
The Large-billed Crow has an extensive distribution throughout the Asian continent. Its range starts from the Indian Subcontinent in the west, extends across China and the Korean Peninsula, and reaches north into Japan. In Southeast Asia, its distribution includes Malaysia, Indonesia, and the Philippines. Due to its vast range and numerous subspecies, the Large-billed Crow exhibits geographical variations in size and coloration. Despite often being found in densely populated human areas, it is not classified as threatened and is listed as "Least Concern" by the IUCN (BirdLife International, 2024) .

Habitat Info
It can be found in dense forests, but it is also frequently present in agricultural lands where food sources are readily available. Crucially, the species has adapted well to human presence, making it extremely common in both urban and suburban environments. Its dietary flexibility supports its broad habitat range; the crow is an omnivorous scavenger, feeding on a wide variety of items, including fruits, grains, insects, small animals, eggs, nestlings, and also food waste from human areas (Nijman, 2011) 

C. Traditional Uses / TK-related Info

▪ Cultural symbolism – The crow holds a complex and often contradictory place in Asian culture. In traditional belief, the crow is commonly associated with negative omens, such as death, bad luck, or misfortune. This connection often stems from its all-black appearance, its scavenging habits, and its harsh calls. However, the crow's behavior also earns it respect; it is widely recognized as a creature of high intelligence, cunning, and remarkable adaptability (Al-Jahani, 2017)

▪ Environmental indicator – the crow acts as an important environmental indicator. Farmers and local inhabitants often rely on the presence, behavior, or nesting patterns of the Large-billed Crow as a reliable sign of changing seasons or shifts in local food availability (Dhaduk & Shingala, 2021). For example, increased activity or movement of crows might signal the onset of a new harvest period or a shift in insect populations 

▪ Folklore and literature – The proverb, "Gagak di hutan, hitam tak sama warna" (A crow in the forest, black but not the same color), specifically references the crow seemingly uniform appearance all black to illustrate a deeper truth, superficial similarity hides essential or hidden differences (Awang, 2017). 

D. Any related scientific studies, such as ecology/ conservation status/threats/diversity

Scientific studies on Corvus species reveal remarkable cognitive abilities such as tool use, problem-solving, and social cooperation. Ecologically, the crow plays a key role as a scavenger, helping to clean up organic waste and prevent disease spread. It is abundant throughout its range and listed as Least Concern by the IUCN.
