The house martin is a common summer visitor to the UK, arriving in April and leaving in October. It builds mud nests, sometimes in small colonies, under ledges, on cliffs and, as their name suggests, under the eaves of houses. Both males and females help to build the nest, collecting mud from streams and ponds and building up layers with bill-sized pellets. House martins are commonly found in towns and villages, as well as in agricultural areas. They feed on flying insects and aphids.Sut i'w hadnabod

House martins will return from their African wintering grounds to the same nesting sites each year. They can reuse their old nests, saving them about ten days' work collecting mud. So don't knock down that empty nest - you never know who might turn up to use it!Gwyliwch
