Tree sparrows prefer open farmland with well-spaced mature deciduous trees in hedges, isolated small woods or pollarded willows along slow flowing rivers, streams and ditches. In the winter they will move onto stubbles, naturally regenerated areas and game cover.
Adults feed on small seeds and insects, whereas chicks are entirely dependent upon insects and spiders for the first two weeks of life.
Tree Sparrows breed between April and early August. Generally they have 2 to 3 broods each season. They nest in colonies in tree holes, willow pollards, farm buildings and nest boxes. Boxes should be placed in groups within the same tree above head height and need a 2.8cm entrance hole.
