### Identification The African Openbill (*Anastomus lamelligerus*) is a medium-sized stork that, at first glance, appears entirely black. However, through a long lens or binoculars, a stunning iridescent sheen of bronze, green, and purple reveals itself across its shaggy plumage. Standing roughly 80–94 cm tall, its most diagnostic feature is its remarkable brownish bill. The mandibles meet only at the tip, leaving a wide, permanent gap in the center—as if the bird can’t quite close its mouth. Unlike the larger, heavier Saddle-billed Stork, the Openbill has a more delicate silhouette and dark, spindly legs.
### Habitat & Range Widely distributed across Sub-Saharan Africa, from Senegal to South Africa, this stork is a water specialist. You’ll find them in lush freshwater wetlands, floodplains, and the reedy margins of shallow lakes. They are highly nomadic, following the rains to find receding waters where their prey becomes concentrated. They rarely venture into deep water, preferring the "marshy soup" of vegetated shorelines.
### Behaviour Observing an Openbill is a lesson in patience. They are gregarious birds, often seen in small flocks or soaring high on midday thermals like dark, ragged kites. In the field, you’ll notice them walking slowly through floating vegetation, peering intently into the water. During the breeding season, they become colonial nesters, often building stick platforms in trees overhanging water, frequently sharing "heronries" with ibises and egrets.
### Diet The Openbill is a biological specialist, focusing almost exclusively on large aquatic snails (particularly Apple Snails) and freshwater mussels. They forage by probing the mud with their sensitive bill tips. Once a snail is located, they carry it to a flat spot or a floating reed bed to perform a "surgical" extraction.
### Fascinating Fact Contrary to popular belief, the gap in their bill isn't for crushing shells! It actually functions like a pair of surgical forceps. The gap allows the bird to grip a slippery snail shell firmly at the tip while its sharp, needle-like lower mandible reaches inside to sever the snail’s attachment muscle. This allows the stork to flick the meat out and swallow it whole, leaving the shell perfectly intact!
