Jenjang dan burung perancah (Cranes & Waders)
African Openbill
Anastomus lamelligerus
- tidak umum
- 38 km/h
- Risiko rendah
Its bill has a permanent gap, evolved to pry open apple snail shells. Looks broken, works perfectly. Like most things.
- Populasi
- No quantified global figure published; species is widespread and described as not globally threatened, with locally common to abundant populations across its sub-Saharan range (populations reported as broadly stable, though some regional declines noted)
- Habitat
- Extensive freshwater wetlands — marshes, swamps, lake and river margins, ricefields and seasonally flooded plains — with tall trees or shrubs nearby for nesting; occasionally uses moist savanna and burnt grassland
- Fakta menarik
- Its bizarre bill — with upper and lower mandibles that meet only at the tip, leaving a persistent gap between them — is not a nutcracker as once assumed; the curved lower mandible instead lets the bird pry beneath a snail's operculum to extract the animal without breaking the shell, an adaptation that becomes more pronounced as the bird matures.
- Sebaran
- Sub-Saharan Africa (widespread, though scarcer in parts of West Africa) and western Madagascar (two recognized subspecies: nominate lamelligerus and madagascariensis); makes regular trans-equatorial migrations tracking wetland/dry-season conditions
- Makanan
- Specializes on aquatic apple snails (genus Pila) and freshwater mussels (Ampullaria); also takes frogs, crabs, worms, fish, and large insects such as locusts and beetles
