- ‘Young birds fledge at 14 to 22 days and are partially dependent on adult birds for 23 to 28 days post-fledging.’
- ‘Often only one nestling fledges from broods in this population of brown pelicans, so the critical fight may be over who is ranked first, rather than who avoids being ranked last.’
- ‘Females generally lay four or five eggs; between zero and four young fledge.’
- ‘Once they fledge, young birds wander long distances in random directions.’
- ‘The female usually stays with the young until this point, but she may leave before the young have fledged.’
- ‘We searched for records of what happens to young birds after they fledge, a stage where many studies cease.’
- ‘Soon after the young have fledged, the red foots congregate and first departure flights commence.’
- ‘Nestlings usually fledge before they can fly and continue to receive parental care for 18 to 20 days.’
- ‘Young birds fledge after a length of time that varies widely between species, but is roughly similar to the length of the incubation period.’
- ‘In late December, chicks fledge, and adults leave the colonies to feed and molt.’
- ‘A total of 1072 eggs hatched, and 518 nestlings fledged successfully.’
- ‘‘When young birds are fledging, they need to learn to find natural foods,’ said the society's Winnie Burkett.’
- ‘Nestlings fledge three to eight weeks after hatching, and are dependent on the parents for supplemental food for several days to weeks after fledging.’
- ‘Four to five days after the young fledge, they can make short flights, and within a week they are strong flyers.’
- ‘On this first day of summer, we are well into the season when baby birds fledge - a desperate time of survival for many young birds.’
- ‘Eventually five young fledged and the next year, five more captive-reared birds were released.’
- ‘The young chicks fledge or leave the nest in around 60 days and become fully independent in 14 more days.’

- ‘All broods except one successfully fledged their young.’
- ‘One female initiated a second nest attempt 24 days after fledging young from her initial nest and successfully fledged a second brood.’
- ‘Those species like the pied kingfisher and the Seychelles warbler, which are able to fledge many more young when assisted, are also the same species that are mostly likely to recognize close relatives.’
- ‘If all goes right at the nest site, it takes eight months to fledge a chick.’
- ‘During the years 2001 and 2002, from the 10 nests observed at the Savannas only one chick was successfully fledged and survived through its first year.’
- ‘In Area 1, one chick was fledged successfully in four nest attempts.’
- ‘This finding supports the prediction of Kuletz, who suggested that adults that deliver mostly low-lipid fishes are less likely to fledge a second chick.’
- ‘Conserving their habitat could involve preserving a patch of scrub or delaying the cutting of a swathe of hay for a few days until a bird has fledged its young.’
- ‘It is possible that those birds renested >10 km from previous nests and eventually fledged young.’
- ‘Furthermore, after recruitment larger females were more likely to successfully fledge offspring, providing a mechanism by which RSD is maintained in the population.’
- ‘A successful nest fledged at least one young (fledging defined as leaving the nest).’
- ‘Although we may have missed a few birds that lost their eggs early, it is unlikely that we missed birds that fledged chicks.’
- ‘Breeding couples are generally able to successfully fledge a chick only once in nine years.’
