In many species, parents continue to care for their fledged young, either by leading them to food sources, or feeding them. Birds are vulnerable after they have left the nest, but before they can fly, though once fledged their chances of survival increase dramatically. [5] A pigeon fledgling on a tiled floor
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]
One of the most important things to remember to help the bluebirds is to stop the invasive non-native house (English) sparrows from nesting in those bluebird nest boxes. House sparrows are vicious ...
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.

The young fledge about 31 days after hatching, and generally move to moister areas in valleys and on the banks of rivers. They may be cared for by their parents for up to 10 days after they fledge, and exceptionally for 81 days after hatching. About 52 to 63% of nests fail to produce any fledged young. Breeding starts after one year of age. [3]
After the juveniles fledge, the family travels and forages together until early fall, when the young birds disperse to avoid competition for food during the winter. Sexual maturity is reached after one year of age. The oldest known wild, banded Blue Jay was at least 26 years, 11 months old when it was found dead after being caught in fishing gear.
