How do I build a house?

The nesting site is varied; under eaves, in holes in masonry or rocks, in ivy or creepers on houses or banks, on the sea-cliffs, or in bushes in bays and inlets. When built in holes or ivy the nest is an untidy litter of straw and rubbish, abundantly filled with feathers. Large, well-constructed domed nests are often built when the bird nests in trees or shrubs, especially rural areas.
