Millions of pink flamingos transform the alkaline waters of Lake Natron in northern Tanzania into a dazzling display daily.

• This spectacle is under threat due to human activities and changing weather patterns, endangering the world's largest migratory bird colony.
• Lake Natron, a Ramsar site on the Tanzania-Kenya border, is uniquely suited for flamingos with its warm, hypersaline waters. However, agriculture, pollution, and climate change are disrupting this delicate ecosystem.
• Senior ecologist John Sule notes that changing water levels and salinity, due to extreme weather, make nesting difficult for flamingos and affect their food supply, causing a population decline.
• Prolonged dry seasons further concentrate salinity, worsening food shortages for the birds. Despite a halted soda ash extraction project in 2008, threats to this habitat persist.
