The Red-eyed Vireos breed in deciduous and mixed forests with the female choosing the nest placement in a fork of a branch that’s concealed from above by vegetation. The female constructs the nest out of bark strips, grass, pine needles, wasp-nest paper, twigs and plant fibres that are carefully glued together with spider-web adhesive and sticky plant fibres. The male will also help with providing these materials. Clutch size is up to 5 eggs, incubation period is 11 – 15 days and nestling period is 10 -12 days. Caterpillars make up 50 percent of their summer diet. They also eat many other kinds of insects including spiders. During migration they eat both insects and fruit. They over-winter in South America. /LEON LORENZ
