💡 Everyday Comparisons for Size, Mass & Speed
- 💡 Just as a person fishes with a fishing rod, it uses stick tools to fish larvae out of wood (Comparison).
- 💡 Such larva-fishing behavior was observed in dry forest on the west coast of New Caledonia (Gouaro-Déva Provincial Park) (Royal Society paper).

📖 1. Overview
The New Caledonian crow is an omnivorous forest bird living on only two islands of New Caledonia, famous for making and using tools.
🦴 2. Anatomy & Morphology
Its bill is unusually straight compared with other crows so it can grip tools firmly, and the overlap between its two eyes' fields of view is wider than in other studied birds, letting it watch the tip of a tool right in front of its eyes.
🔍 3. Ecology & Behavior
It uses sticks or leaf stems to fish beetle larvae out of rotting wood and also crafts complex tools cut from the barbed edges of pandanus leaves. This bird is known to make three distinct types of tools in all.
🇰🇷 4. Connection to Korea
No direct record connecting this species to Korea has been found.
