They wear much plainer clothes than the Bluebirds and Robins, on their olive or russet-brown backs and light-tinted, dark-spotted breasts, but have the most beautiful voices in all Birdland.

The names of these wonderful singers, who make a musical quartette, are Wood Thrush, Hermit Thrush, Wilson's Thrush, and Olive-backed Thrush; but you will have to keep both your eyes and ears open to learn to tell them apart and name them rightly."

Do you think he might be one of these Thrushes?
He is singing now, Uncle Roy." And Dodo began tugging at the Doctor's hand, to lead him down the steps.

"What is it?
What are you waiting for ?" whispered Nat.

"A bird?
Where ?" The bird answered Nat's question itself, telling him by its song in what part of the tree it was perching.
