A myriad of bird species have evolved to nest within the cavities of house walls. This unique nesting behavior entails a significant concern for homeowners, yet it is fascinating from an ornithological perspective. The question of what birds nest in house walls often hinges on the geographical location and the types of homes in question.
Among the most common birds that nest in house walls are sparrows and starlings. Both species have adapted to urban living and find the small crevices and holes in buildings to be ideal nesting sites. Starlings are known to be particularly aggressive, often displacing other birds from their nests. Sparrows, on the other hand, are more opportunistic and adaptable, willing to nest anywhere they can find sufficient space.
Swallows are another bird species that often nest in house walls, particularly under eaves or within vent openings. Their nests, made of mud and saliva, are usually built on vertical surfaces with some overhead protection, making house walls an attractive option.
Woodpeckers also occasionally nest in house walls, drilling holes into wooden siding to create a cavity for their eggs. In addition to creating potential structural damage, their persistent drumming can be a nuisance to homeowners.
Additionally, the European swifts are known for their preference for high, inaccessible places like church steeples and house walls for nesting. They return to the same spot year after year, making them a perennial presence for many homeowners.
Birds nesting in walls is a common occurrence worldwide due to the availability and security these man-made structures offer. However, it’s important for homeowners to ensure that these nests do not cause significant damage to their property or create health risks due to accumulated droppings or mites. Professional bird control services can assist in safely removing these nests and suggesting preventative measures to avoid future avian intrusions.
