Water is fundamental to sustaining life on our planet. Migratory birds rely on water and its associated habitats—lakes, rivers, streams, ponds, swamps, marshes, and coastal wetlands—for breeding, resting, refueling during migration, and wintering. Yet increasing human demand for water, along with climate change, pollution, and other factors, are threatening these precious aquatic ecosystems.
Headlines around the world are sounding alarm: 35 percent of the world’s wetlands, critical to migratory birds, have been lost in the last 50 years. Utah’s Great Salt Lake, the largest saltwater lake in the Western Hemisphere and used by more than a million shorebirds, is in danger of disappearing within five years. Across the Amur-Heilong Basin in Asia, climate change is amplifying the impact of habitat destruction by depleting natural water systems and depriving migratory birds of vital breeding and stopover site. These sobering examples go hand-in-hand with recent reports that reveal that 48 percent of bird species worldwide are undergoing population declines.
Water and its importance to migratory birds – and the increasing threats to both water quality and quantity – is the focus of this year’s World Migratory Bird Day, a global campaign that aims to raise awareness of migratory birds and the need for international cooperation to conserve them. Activities to mark the campaign will be held globally on two peak days in May and October under the theme “Water: Sustaining Bird Life”.
