The preferred locations for the autumn display are old Eurasian tree sparrow nests, particularly those where nestlings had hatched.

From 1981 to 1982, three independent swallow pairs were observed co-occupying the nest boxes of western bluebirds. These violet-green swallows protected the nesting site, removed fecal sacs from the boxes and fed the bluebird fledglings with no resistance from the adult western bluebirds.

[1] [2] For altricial birds, those that spend more time in vulnerable condition in the nest, the nestling and fledging stage can

The ducks, primarily cavity nesters, prefer the confines of a hollow tree but will nest on the ground when necessary. They also make use of chimneys, abandoned buildings, or nest boxes, the latter having been increasingly provided to them over recent decades, especially in southeast Texas and Mexico. Ducklings leap from nest cavities within two ...
The nest is a shallow bracket made of sticks, which the birds gather in flight, breaking them off trees. The sticks are glued together (and the nest to a vertical surface) with copious amounts of the bird's saliva . [ 57 ]
A juvenile bird during the period it is venturing from or has left the nest and is learning to run and fly; a young bird during the period immediately after fledging, when it is still dependent upon parental care and feeding.
