The RSPB are asking the public to protect House Martin nests by reporting anyone who removes them during the breeding season.
House Martins can be seen building their almost spherical mud nests on the sides of houses or farm buildings, usually just under the eaves in a sheltered corner, or on a southerly facing wall to get the warmth of the sun.
A House Martin nest is painstakingly constructed from hundreds of clumps of wet mud mixed with straw and grass to make a closed cup shape, with just a small hole as an entrance and exit. Adult birds will fix old nests and add to them, often using the same nest year after year.
