Preventing house martins from nesting

With house martins amber listed due to their population decline, it is inappropriate to prevent them nesting. While most people welcome house martins, the birds can occasionally be a problem, for instance if a nest is above a door. These conflict areas can be isolated by closing in the triangle under the eaves where the nests are built with a piece of wood, fine mesh chicken wire or parallel wires stretching from the outer edge of the soffit board to c.15cm down the wall. 

Do not deny martins access to parts of the roof where their presence does not create a problem. Never put these deterrents in position to prevent access to an active nest and only remove existing nests, if essential, during the winter months when the martins are not in residence.  

Knocking down an active nest or preventing birds access to their eggs or young is illegal and attracts potentially high penalties.
