Wild House Martin Nesting Urban

House martins have declined significantly in the UK. Supporting their nesting in urban and suburban environments is a key conservation priority.

Key Facts

UK house martin populations declined by approximately 52% between 1969 and 2019
They build cup nests of mud pellets under eaves
New buildings with smooth soffits and overhanging eaves are unsuitable
Artificial nest cups installed under eaves are used successfully
Mud access near nest sites is essential for nest construction

Welfare Considerations

House martins returning to find nest sites removed during building renovation face displacement that prevents breeding. Artificial nest cups that replace lost natural sites prevent displacement welfare harm. Providing mud access near nest sites supports pair ability to construct and repair nests.

What You Can Do

Install artificial house martin nest cups under suitable eaves
Provide a shallow mud pool near suitable nest sites
Advocate for house martin nest cup requirements in planning for renovated buildings
