Hi Tessie The majority of British nesting birds are protected under law. and it is unlawful, in anyway, to disturb a nesting bird. You haven't established whether the nests are actually under the tiles or, are being attached to the brickwork below the eaves. i.e. house martin. While I can sympathize because of the "mess" , personally, I think it is a small price to pay for the privilege of having birds nesting in/on my house. We have house martins, sparrows and starlings and they are an absolute joy.! Best wishes David
