Post-fledging survival, movement patterns, and habitat associations of Bendire's Thrashers ( Toxostoma bendirei ) in the Chihuahuan Desert

open access: yesAvian Conservation and Ecology, 2023
Knowledge gaps about the basic demography of a species facing population declines impede conservation efforts. For many passerine species, the survival rate of the post-fledging stage is unknown but may directly contribute to population trajectories ...

Post-fledging care, multiple breeding and the costs of reproduction in the great tit [PDF]

open access: yesAnimal Behaviour, 1996
In species that initiate multiple broods in a single season there is usually a trade-off between the number of young in the first brood, and the timing and occurrence of subsequent broods in the same season. The hypothesis that experimental reduction of clutch size reduces the duration of post-hedging care was tested in great tits, Parus major, and the

Behavior and ecology of post-fledging American Kestrels

open access: yes, 2018
We observed the development of foraging behavior after nest departure in 12 sibling groups of American Kestrels (Falco sparverius). Perch resting decreased whereas perch hunting, eating self-captured prey, and flying increased over the 5-wk period that young were observed. Kestrels used perch hunting more than other types of hunting and fed exclusively

Post-fledging survival, movements, and habitat associations of Gray Vireos in New Mexico

open access: yesAvian Conservation and Ecology, 2022
Annual population growth in songbirds can be particularly sensitive to post-fledging survival, but research and management are frequently biased toward the nesting stage.

Post-fledging movements of Atlantic Puffins from Skomer Island [PDF]

open access: yesSeabird Journal
The movements of seabirds during the immature period generally remain poorly understood, primarily due to the challenges involved with tracking birds that do not regularly return to a nest. This knowledge gap prevents us from gaining a full understanding of the areas used by seabird populations.

Cooperative breeding shapes post-fledging survival in an Afrotropical forest bird. [PDF]

open access: yesEcol Evol, 2017
AbstractFor avian group living to be evolutionary stable, multiple fitness benefits are expected. Yet, the difficulty of tracking fledglings, and thus estimating their survival rates, limits our knowledge on how such benefits may manifest postfledging.

Association of Sex, Fledging Date, and Sibling Relationships with Post-Fledging Movements of Burrowing Owls in a Nonmigratory Population in the Imperial Valley, California [PDF]

open access: yes
Natal dispersal is an important driver of population and colonization dynamics, yet factors that affect timing and distance of post-fledging movements are poorly understood.

Post-fledging habitat use in the Dickcissel [PDF]

open access: yesThe Condor, 2017
ABSTRACT Effective habitat management requires understanding habitat needs across a species' life history stages. In songbirds, management of breeding habitat is generally focused on the pre-nesting and nesting stages, while habitat use during the critical post-fledging stage remains understudied and is seldom a target for management. In 2014 and 2015,

Post‐fledging care, philopatry and recruitment in brown thornbills [PDF]

open access: yesJournal of Animal Ecology, 2001
Summary We describe patterns of post‐fledging care, dispersal and recruitment in four cohorts of brown thornbillsAcanthiza pusilla. We examine what factors influence post‐fledging survival and determine how post‐fledging care and the timing of dispersal influence the probability of recruitment in this small, pair breeding, Australian passerine ...
