Asian Openbill
Begur Kere,Karnataka
Back in West Bengal, we used to see a lot of Open-bill Storks in the Rajarhat area. In Bangalore, we don't see them as much. These birds need shallow water to find crustaceans or snails, which Begur Lake provides. That’s why we see this bird in flocks, searching for food. It’s fascinating how they find snails by dipping half of their beak into the water. Once they catch their food, they hold it in the open part of their bill and fly away to a safer spot to eat peacefully. Generally, when a stork catches something, other storks try to snatch it, avoiding the hard work of hunting. Open-bill Storks are no exception.
Information of Asian Openbill
| IUCN (International Union for Conservation of Nature): | Least Concern |
|---|---|
| Approximate size(adult): | Length about 68–81 cm; wingspan 105–125 cm; weight ~1–1.3 kg. Medium-sized stork with greyish-white plumage and a characteristic gap between the upper and lower mandibles of the bill. |
| Resident/ Migrate from: | Mainly resident in South and Southeast Asia, with some seasonal local movements following water availability. |
| Migrate to: | No long-distance migration; some populations move locally to wetlands during dry season or for breeding. |
| Breeding season: | In India: generally July to September, coinciding with monsoon and availability of freshwater snails (primary food source). In other parts of range, timing may vary slightly with local rainfall. |
| Breed in: | Nests in colonies, often on trees in wetlands or sometimes in reedbeds. Nests are made of sticks, lined with leaves. Clutch size is usually 3–5 eggs. Both parents incubate and feed the chicks. |
| Habitat: | Freshwater wetlands: ponds, lakes, marshes, paddy fields, and shallow rivers. Avoids saline or deep water bodies. Often found foraging in groups in flooded agricultural fields. |
| Diet: | Specialized feeder: primarily freshwater snails, supplemented by frogs, insects, and small aquatic animals. Uses the gap in its bill to extract snails efficiently from shells. |
