Songbirds Spring has come! Listen to the birds sing! Noisy songbirds have been busy making their nests. Peep! Peep! Baby birds are being born! The tui is a New Zealand songbird. It is very good at sounding like other birds it hears. A robin makes a nest of twigs, grass, and leaves.
The robin's blue eggs will soon hatch. The father feeds the chicks while the mother gets more food. The male robin has a bright red breast. It's a fact! In most songbirds, only the males can sing.
Water birds Swans are graceful swimmers. Like many other water birds, they can also walk and fly. But watch out if you make this one mad! It will hiss loudly! A swan has a short tail. A long neck helps a swan reach plants underwater to eat. It's a fact! Most ducklings (baby ducks) Can swim and run on the day they hatch, but they cannot fly for several weeks.
Water rolls off the swan's feathers. Webbed feet make the swan a good swimmer. Geese are fast fliers as well as strong swimmers. They fly to warmer places when the weather gets cold. Geese form a v as they fly together in the sky.
