Spain's Annual Flamingo Ringing Begins In late spring, hundreds of Greater Flamingos gather at the shallow waters of the Guadalquivir River delta in Donñana National Park, Andalusia.
This event marks the start of the annual flamingo ringing program, a conservation effort that combines ornithological research with community outreach.
Donñana National Park is home to a thriving population of Greater Flamingos, with numbers estimated in the low thousands.
