WEC260: Florida's Introduced Birds: House Sparrow (Passer domesticus)

Figure 9. House Sparrows build messy nests of dried vegetation in any available space on urban structures—under eaves, above and behind gutters and drainpipes, in and around vents, and especially around signs. These nests should be prevented or removed because they can cause fire hazards and clog drains, and the droppings that accumulate under the nests can present a health hazard and cause unsightly stains.
