Bird nests are also built by humans to help in the conservation of certain birds. For example, artificial [[swallow]] nests are generally built with plaster, wood, terracotta or stucco.<ref>[http://www.americanartifacts.com/smma/per/nesttest.htm Artificial swallow nests] {{webarchive|url=https://web.archive.org/web/20140317105512/http://www.americanartifacts.com/smma/per/nesttest.htm |date=17 March 2014 }}</ref><ref>[http://shopping.rspb.org.uk/swallow-nest.html Terracotta nests] {{webarchive|url=https://web.archive.org/web/20140317111246/http://shopping.rspb.org.uk/swallow-nest.html |date=17 March 2014 }}</ref>

Artificial nests, such as [[nest box]]es, are an important conservation tool for many species, however nest box programs rarely compare their effectiveness with individuals not using nest boxes. Red-footed falcons using nest boxes in heavily managed landscapes produced fewer fledglings than those nesting in natural nests, but also than pairs nesting in nest boxes in more natural habitats.<ref>{{cite journal |author1= Bragin, E.
