They do not go far from the nest, return to it at night, and take some weeks to completely leave the nest. Many fledglings are found on the ground and in low shrubs during this period, where they continue to be cared for until they can make their way up into the trees. These birds are often mistakenly 'rescued'.
Of 357 pairs in the woodlands around west Berlin in 2 decades starting 1958, 160 pairs produced 333 fledglings, with an average of 2.08 per successful nest. 13 pairs in the city parks of west Berlin produced 47 fledglings, 3.3 pairs per successful nest, productivity strongly correlated to number of yellow-necked mice available.

Fledglings have also been reported to invade their own or neighbouring nests and evict a new brood. [31] Common starling nests have a 48% to 79% rate of successful fledging, although only 20% of nestlings survive to breeding age; the adult survival rate is closer to 60%.
Bald Eagle Nests. Bald eagle pairs often return to their nests year after year, continually adding to it and upgrading it as the years pass. The bulk of the nest is built from large branches, and ...
Birds, in particular, that disperse as fledglings will take advantage of exceptional navigational skills to return to a previous site. [9] Philopatric individuals exhibit learning behaviour, and do not return to a location in following years if a breeding attempt is unsuccessful. [10]
