Tree Swallow

A common swallow of marshes and open fields, the Tree Swallow is a ready inhabitant of nest boxes. Thier nests are mosty neat and organised. They feed on small bugs and they uses many feathers from other birds in its nest. The feathers help keep the nestlings warm so they can grow faster. They help keep levels of ectoparasites, like mites, low too
