Wild Barn Swallow Nesting Welfare

Barn swallows build mud nests inside farm buildings and other structures, with access to traditional nesting sites and insect-rich habitats affecting breeding welfare.

Key Facts

Swallow populations have declined by 39% since the 1970s
They require access to barns and open buildings for nesting protected from weather
Mud and grass for nest construction must be available near nesting sites
Aerial insect abundance for chick feeding has declined with intensification
First broods in May-June followed by second broods allow two or three breeding attempts

Welfare Considerations

Barn swallow breeding welfare depends on access to appropriate nesting buildings and abundant aerial insects. Building renovation that prevents swallow access and insect decline from pesticide use are the primary welfare pressures affecting this charismatic summer visitor.

What You Can Do

Leave barn doors open during swallow breeding season to maintain access to nesting sites
Create insect-rich habitat near swallow nesting buildings through wildflower planting
Report swallow nest sites to your local Wildlife Trust to support monitoring
