The size and exact shape of the hornero nest varies depending on the ...
Especially in warmer areas, the house sparrow may build its nests in the open, on the branches of trees, especially evergreens and hawthorns, or in the nests of large birds such as storks or magpies. [ 133 ] [ 142 ] [ 145 ] In open nesting sites, breeding success tends to be lower, since breeding begins late and the nest can easily be destroyed ...

Hirundo species also build open nests, Delichon house martins have a closed nest, and the Cecropis and Petrochelidon swallows have retort-like closed nests with an entrance tunnel. [ 8 ] The genus Ptyonoprogne is closely related to the larger swallow genus Hirundo , and is sometimes included within it since the nests of the Ptyonoprogne crag ...
More than 40 beetle species have been recorded in common house martin nests, but most are either typical of the locality or found in the nests of other birds. The typical number of individuals, around 200, is relatively low compared to other bird species (1,400 individual beetles for house sparrow, 2,000 for sand martin). The beetles have no ...
Nest in a nest box. The western bluebird nests in cavities or in nest boxes, competing with tree swallows, house sparrows, and European starlings for natural nesting locations. Because of the high level of competition, house sparrows often attack western bluebirds for their nests. The attacks are made both in groups or alone.
The Ptyonoprogne species construct an open mud nest and therefore belong to the last group; Hirundo species also build open nests, Delichon house martins have a closed nest, and the Cecropis and Petrochelidon swallows have retort-like closed nests with an entrance tunnel.

It often nests in colonies, some being quite large. Bird houses are also a suitable nesting site. Four to seven eggs are in a clutch.
