On the Isle of Man the House Martin is a common passage migrant and summer visitor. In most years, the first few birds are usually seen in the second half of March, though these are probably not part of the Manx breeding stock. Most local nests are not re-occupied until the middle of April. House Martins can have two, sometimes three broods, so can still have young in the nest as late as October. They spend the winter in Africa, south of the Sahara.

Sometimes non-birdwatchers may confuse House Martins with Swallows. While House Martins make a mud nest that is stuck on the outside of a building (or on a cliff), Swallows will usually nest inside, even if it is only a porch. Only the House Martin has the vivid white rump.

Manx Bird Atlas survey 1998 – 2003

On the Island, House Martins have an extensive lowland breeding distribution, which appears to be influenced by two main factors. The first is the availability of nest sites, thus they are largely absent from upland areas, and also from the Ayres in the north and from the south–west coast. The second factor is the availability of food, which probably accounts for the lack of breeding in the centres of the Island’s larger towns, such as Douglas and Ramsey, where suitable nest sites appear to be available. Nests were found on only two natural sites, one on the cliffs south-west of Port Soderick at Gob Lhiack, where 27 nests were found and one nest at Port Soderick itself; these represent just over 1% of the estimated Manx breeding population of 1,456 – 1,714 pairs.
