The 'red-eyed vireo' (Vireo olivaceus) is a common songbird found in North American forests, known for its distinctive red eyes and persistent singing. They are medium-sized with olive-green plumage and a gray head. They are insectivores, feeding on insects and spiders in the forest canopy. Red-eyed vireos are migratory birds, spending summers in North America and winters in South America. Think of them as the tireless singers of the summer forest.
