The story
A roost worth protecting
Every October, barn swallows start arriving in KwaZulu-Natal from Europe, where they breed over the northern summer. Each bird weighs less than 20 grams, and some have come from as far north as Finland.
By day they spread out over the farms and valleys, hunting insects. In the half hour before sunset they come back to Lake Victoria and gather over the reeds, swirling and climbing until the sky is full of them. Then they drop into the reed bed all at once, and within minutes it's quiet. They sleep on the reeds overnight and leave again at first light.
People in Mount Moreland have watched this since the 1970s. The roost holds more than one percent of the world's migrating barn swallows, and BirdLife International declared the wetland an Important Bird Area in 2007.
When King Shaka International Airport was approved at La Mercy in 2006, the roost became a problem: a sky full of swallows next to a busy runway is a serious bird-strike risk. The community campaigned to protect it. One of the conditions of the airport's approval was that flights be planned around the swallows, and a bird-detecting radar at the end of the runway was among the first of its kind at a South African airport.
In 2026 the airport added a new 3D radar that can follow thousands of birds at once. Researchers at the University of KwaZulu-Natal are using it to learn when the swallows arrive, when they leave, and how they move each evening.
The viewing site first opened in 2006. After a few poor seasons it closed in 2019, and since 2024 it has been run by volunteers from Mount Moreland Monitors. Your entry pays for the site's upkeep, and every rand goes to the Monitors.
