Bird
Large-billed Crow
Corvus macrorhynchosAlso known as Jungle Crow, Thick-billed Crow, Japanese Large-billed Crow
Large-billed crows thrive in diverse environments across Asia, from wild montane forests to dense urban centers where they drop hard-shelled nuts into crosswalks for traffic to crack. Their remarkable problem-solving abilities and bold foraging strategies allow them to dominate urban ecological niches. Distinctive deep vocalizations and massive arched beaks make them prominent, highly visible members of local wildlife communities.

Interaction riskLow
- Low
- Moderate
- High
- Very high
- Why interaction risk is low
- May dive-bomb or scratch when defending fledglings; maintain distance from active nests.
- Why it is dangerous
- Adult crows aggressively defend nests by dive-bombing, pecking, or scratching perceived threats to their fledglings.
- How to recognize a risky encounter
- Listen for deep, guttural caws and look for birds displaying flared wings or perched near stick nests.
- What to do
- Wear a hat or hold an umbrella overhead when passing under active nests, and do not approach fallen fledglings.
Responsible observation
- Observation: Watch urban parks during late afternoon to observe massive communal roosts assembling.
- Nesting Caution: Give active nests wide clearance in spring, as adults vigorously dive-bomb intruders.
- Identification: Look for the heavily arched, massive black bill and steep forehead profile to distinguish it.
