\nCliff swallows nest in colonies and often live in close association with humans. Many swallow colonies on buildings and other structures are innocuous. In some situations, however, they can become a major nuisance, primarily because of droppings they deposit. In such instances they may create aesthetic problems, foul machinery, and cause health hazards by contaminating foodstuffs. Their mud nests eventually fall to the ground and can cause similar problems. Parasites found in swallow nests, including swallow bugs, fleas, ticks, and mites, may bite humans and domestic animals, although these are not the usual hosts. In addition, cliff swallow nests are often used by house sparrows, introducing another avian pest and its attendant damage problems and potential health hazards.<\/p>\n","protected":false},"excerpt":{"rendered":"
