Post-fledging movements, mortality and migration of juvenile northern gannets [PDF]

Marine Ecology Progress Series, 2021
Studying the at-sea movements and behaviour of juvenile seabirds is logistically challenging, but new technologies now allow tracking birds on their first migration, giving a more complete picture of population-level spatial ecology. We investigated the post-fledging migration of juvenile northern gannets Morus bassanus from the world’s largest colony,

Post-fledging habitat selection in a rapidly declining farmland bird, the European turtle dove Streptopelia turtur

, 2017
Post-fledging survival plays a vital role in the dynamics of bird populations and yet is the least studied avian life-stage. Habitat requirements post-fledging may have important implications for behaviour and survival, especially for declining ...

Insights into the development of a juvenile harpy eagle’s hunting skills [PDF]

Acta Amazonica, 2019
The post-fledging period is of paramount importance for raptors, since this is when a juvenile develops its hunting skills and gains the abilities required in adulthood and independence through dispersal.

Exogenous corticosterone and melanin-based coloration explain variation in juvenile dispersal behaviour in the barn owl (Tyto alba).

PLoS ONE, 2021
Natal dispersal affects many processes such as population dynamics. So far, most studies have examined the intrinsic and extrinsic factors that determine the distance between the place of birth and of first breeding. In contrast, few researchers followed

Fat chance? Endangered penguin rehabilitation has mixed conservation outcomes

Conservation Science and Practice, 2021
Rehabilitation of sick or injured wildlife supports wild populations of threatened species by improving the health of individuals. Post‐release assessment of the efficacy of rehabilitation relies on re‐sighting and identification of both rehabilitated ...

High post-fledging survival and site persistence using mark-resight methodology for Oregon Vesper Sparrows in the Willamette Valley, Oregon

Avian Conservation and Ecology
The ecology of the post-fledging period for small passerine birds is one of the least known stages of the avian life cycle with high rates of mortality for many species.

Satellite telemetry suggests significant regional variation in post-fledging survival of Adélie penguinsSatellite telemetry suggests significant regional variation in post-fledging survival of Adélie penguins [PDF]

Royal Society Open Science
Post-fledging periods represent one of the most vulnerable stages for juvenile seabirds. Adélie penguins Pygoscelis adeliae must quickly develop foraging skills while minimizing predation risk immediately after fledging.

Does hatch date set the clock? Timing of post‐fledging movements for families of a colonially breeding, long‐distance migratory songbird

Journal of Avian Biology, 2022
Factors that influence the development of migration timing in juvenile songbirds have implications for the ability of individuals to respond positively to rapid environmental changes.
