Sparrows
Here in the Villages it's mostly the bluebirds that are displaced by the invasive sparrow.
Problems With House Sparrows
House sparrows can cause many problems for native birds, including competing for nesting sites, even killing adult birds, hatchlings, and eggs; taking over food sources and reducing diversity at feeders; and crowding out less aggressive birds from traditional ranges and habitats. While all bird species may suffer somewhat from the invasion of house sparrows, particularly vulnerable species include:
Eastern and western bluebirds
Purple martins
Tree and cliff swallows
Orioles
These birds are often in direct competition with house sparrows for food and nesting sites, and house sparrows’ more aggressive, bullying behavior is often successful in displacing them.1
