Redwings are a migratory bird and visit the UK in around September/October. They over-winter in the warmer climate that the UK and Europe offer, and some travel further south. They breed in Northern Europe between May and July and lay their eggs in nests that are built close to the tree trunk. The nest is made from dry grass, small twigs and moss and the is cup shaped and made by the female, with incubation of the eggs at around 13-15 days. The chicks fledge 13-15 days after hatching and are fed in the nest by both adults. The eggs are pale blue or greenish blue with red to brown speckles and are glossy and smooth. The Redwings migrate away from the harsh winter that Northern Europe experiences, feeding on most snails, spiders and red berries that form on the Holly and other bushes. They also eat worms and small invertebrates. The male and female are very similar, and Redwing and Fieldfare often can be found together feeding.
