Wild House Martin Welfare and Nesting

House martins build mud nests under eaves across the UK and face welfare challenges from nest loss during renovation, insect decline and changes in mud availability.

Key Facts

House martin nests are protected under the Wildlife and Countryside Act once occupied
They return to exactly the same nest site each year with strong nest site fidelity
Plastic artificial house martin cups can replace lost mud nests and are adopted successfully
Mud availability near nesting sites is essential - artificial mud bowls can supplement scarce natural sources
Insect prey decline due to pesticide use and light pollution is a major welfare threat

Welfare Considerations

House martin welfare requires both nest site protection and insect food supply. Artificial nest cups compensate for renovation losses while native planting and pesticide reduction address the food supply problem.

What You Can Do

Install house martin cups under eaves if you have renovated buildings they previously used
Provide a damp mud area near nesting sites to support nest building material collection
Avoid renovation work on occupied nest sites between May and September
