“What an energetic, explosive song this vireo has . . .
If you were to dissect each one of his songs into its component notes, you’d be astounded at what’s there, as most of those tiny, snappy notes are call notes imitated from other birds! The sharp whit whit call notes of a Wood Thrush, the klee-yer note of a Northern Flicker . . . the jeeer call of a Carolina Wren . . . and more, all make appearances in the White-eyed Vireo’s impressive songs.”
