Red-eyed Vireo

• It is one of the most tireless birds in the world: one male was documented giving more than twenty-two thousand song phrases in a single day, and its habit of singing without pause even in the hottest hours has earned it the nickname "preacher bird".
• It is one of the most frequent victims of the brown-headed cowbird, the North American brood parasite, and in some areas more than half the nests contain another bird's eggs.
• Despite being extremely abundant, it is a bird almost nobody sees: it sings from the canopy and moves slowly among the leaves, and most records of it are by ear.
