Do house martins use the same nest each year?

Yes, house martins often use the same nest each year. They are known for their strong nest-building skills and will repeatedly use the same nest, year after year, unless it becomes damaged or destroyed. House martins typically build their nests under eaves or other sheltered areas of houses or buildings, using mud, grass, and other natural materials. Once a nest is built, the house martins will return to the same location each year to refurbish and reuse the nest for breeding and raising their young.
