The swallow, or 'barn swallow', is a common summer visitor, arriving in April and leaving in October. It builds mud and straw nests on ledges, often in farm buildings and outhouses, or under the eaves of houses. Swallows are widespread and common birds of farmland and open pasture near water. They are agile fliers, feeding on flying insects while on the wing. Before they migrate back to their wintering grounds in Africa, they can be seen gathering to roost in wetlands, particularly reedbeds.
