More than 1% of the global population of Barn Swallows winters in the Mount Moreland Reedbed, an Important Bird Area in South Africa. The site is close to Durban, where an airport expansion threatens to clear the area to make way for landing aircraft. BirdLife South Africa opposes the proposal. The swallows breed in Europe and then migrate down to South Africa to spend the winter there. Read more about the proposed expansion.
