Post-Fledging Survival in Passerine Birds and the Value of Post-Fledging Studies to Conservation

Journal of Wildlife Management, 2014
ABSTRACT Conservation efforts are most effective when we have complete demographic information for a species of concern. Nevertheless, fundamental gaps in our knowledge of demography still exist for many taxa.

Post-fledging Parental Investment in the Capricorn Silvereye

Emu - Austral Ornithology, 1988
We measured relative parental investments of 23 pairs of Capricorn Silvereyes Zosterops lateralis chlorocephala in the post- fledging period to examine the possibility of brood division and to relate parental investment to the survival of parents and offspring. Both parents invested similarly in nestlings and young fledglings.

Post-Fledging Survival of Altricial Birds: Ecological Determinants and Adaptation [PDF]

open access: yesJournal of Field Ornithology, 2016
For altricial young, fledging is an abrupt step into an unknown environment. Despite increasing numbers of studies addressing the post-fledging period, our current knowledge of the causes and consequences of post-fledging survival remains fragmentary. Here, we review the literature on post-fledging survival of juvenile altricial birds, addressing the ...

Post-fledging Movements of Sprague's Pipit

The Wilson Journal of Ornithology, 2009
Abstract Sprague's Pipit (Anthus spragueii) is a threatened grassland songbird that has been described as one of the least known species in North America. We attached radio transmitters to 19 Sprague's Pipit nestlings in south-central Saskatchewan in 2004 and 2005 as part of a study to quantify post-fledging movements.

Post-Fledging Survival of Burrowing Owls in Saskatchewan

The Journal of Wildlife Management, 2003
Extensive research into the decline of the endangered burrowing owl (Athene cunicularia) has focused on breeding biology, but has largely ignored the post-fledging period. To determine whether post-fledging survival was an important factor in the decline we used radiotelemetry to monitor post-fledging juveniles in a migratory population of burrowing ...
