They generally fledge about 18 to 22 days after hatching. The tree swallow is sometimes considered a model organism, due to the large amount of research done on it. An aerial insectivore, the tree swallow forages both alone and in groups, eating mostly insects, in addition to mollusks, spiders, and fruit. The nestlings, like the adult ...
Bluebirds have two or three nestings per year so do not give up trying to attract them. Keep monitoring your bluebird nest boxes and make sure that they aren’t occupied by house sparrows.
Predators of young bluebirds in the nests can include snakes, cats, and raccoons. Bird species competing with bluebirds for nesting locations include the common starling, American crow, and house sparrow, which take over the nesting sites of bluebirds, killing young, smashing eggs, and probably killing adult bluebirds.

This species is a small swallow at 18–25 centimetres (7.1–9.8 in). The adult birds have a highly lustrous dark metallic steel-blue appearance with long tail streamers, which are particularly noticeable in males. White feathers are visible on the rump and flanks when the birds are preening and especially during courtship.
Young birds generally stop producing fecal sacs shortly before they fledge. [8] Removal of fecal material helps to improve nest sanitation, which in turn helps to increase the likelihood that nestlings will remain healthy. [9] It also helps to reduce the chance that predators will see it or smell it and thereby find the nest. [10]
