Each year, flocks of lesser flamingos arrive at Langebaan Lagoon to feed on the rich algal blooms that develop in the warm, sheltered shallows. This year, sightings have been exceptional — with counts of over 2,000 birds on some days in the northern section of the lagoon.
Why Flamingos Come to Langebaan
Langebaan Lagoon offers flamingos exactly what they need: shallow, calm water with abundant cyanobacteria (blue-green algae) and diatoms. These microscopic organisms are the primary food source of the lesser flamingo. The lagoon's protected status within the West Coast National Park means the birds can feed undisturbed for weeks at a time.
Lesser flamingos filter-feed by sweeping their uniquely shaped, upside-down bill through the water, using a highly efficient lamella system to separate food particles from water and mud. Watch closely on the live stream and you'll see this distinctive side-to-side sweeping motion.

Where to Spot Them
Flamingos congregate in the northern section of the lagoon, particularly around the mudflats near the park's Geelbek area. They can also be seen from the R27 road bridge at the lagoon's southern entrance. When present in large numbers, flocks are sometimes visible from the Shark Bay cam as they fly north over the water.
Best Times to Watch
Flamingos feed most actively in the early morning when the water is calm and flat.
Flamingo numbers peak during the warm summer months when algal blooms are at their richest.
Flamingos prefer to feed on the exposed mudflats. Check the tide table and aim for low or outgoing tide.
Conservation Status
Lesser flamingos are classified as Near Threatened on the IUCN Red List. The global population is estimated at 1.5–2.5 million birds, but breeding success is highly variable — they rely on a small number of very specific breeding sites in East Africa. South African sightings are primarily non-breeding birds using the rich coastal feeding grounds.
The West Coast National Park provides critical undisturbed feeding habitat. Disturbance by boats, dogs, or people approaching too closely can cause the entire flock to flush — burning vital energy reserves.
