Reed Wetland · Wetlands10 / 12Wetlands, migrating birds and deltas: 8 facts for kids
Wetlands are the Earth’s kidneys: reeds clean the water and migrating birds return every year. Reed Wetland is one of the Earth’s kidneys: reeds and mud trap some of the dirt so the water runs clearer, and migrating birds stop here every year. Beaver dams change the water level, and where the river meets the lake a branching delta forms. Your child helps clean the water and waits for the birds to return.
