The Post‐Fledging Period in a Tropical Bird: Patterns of Parental Care and Survival
Journal of Avian Biology, 2010 How environmental conditions affect the timing and extent of parental care is a fundamental question in comparative studies of life histories. The post‐fledging period is deemed critical for offspring fitness, yet few studies have examined this period, particularly in tropical birds.

Observations on the Post-Fledging Dependence Period of Cape Vultures
Ostrich, 1985Summary Robertson, A. S. 1985. Observations on the post-fledging dependence period of Cape Vultures. Ostrich 56: 58–66. Cape Vultures were observed during their post-fledging dependence period at a colony in the Cape Province, South Africa. Information is presented on the length of the period, behaviour of juveniles and of parents at the nest, survival

Long-term dynamics of bird use of clearcuts in post-fledging period
The Wilson Journal of Ornithology, 2014ABSTRACT We focus on bird use of clearcuts resulting from even-aged management as part of the Missouri Ozark Forest Ecosystem Project (MOFEP). The long-term nature of MOFEP allows us to present a 15-year monitoring of bird use of MOFEP clearcuts in July using constant effort mist-netting.

Gap Crossing Decisions by Forest Songbirds during the Post‐Fledging Period
Conservation Biology, 1997Gaps in forest cover, created by agriculture, forestry, and other anthropogenic activities, are assumed to impede the movements of many forest songbirds. Little is known, however, about the reluctance of different species of birds to cross habitat gaps. We studied this by inducing birds in the post‐fledging period to cross gaps of varying widths and to

AbstractThe conservation importance of the post‐fledging period in migratory birds has been scarcely assessed. In this study, we examined the space use and habitat selection of radio‐tagged lesser kestrels Falco naumanni at two spatial scales during summer in north‐western Spain, where premigratory aggregations of around 1000 lesser kestrels occur ...

Do mature forest birds prefer early-successional habitat during the post-fledging period?
Forest Ecology and Management, 2012Recent studies have highlighted the importance of the post-fledging period to bird populations, suggesting that the importance of this portion of the life cycle is equal to or greater than the nesting period. Nevertheless, few studies have compared abundance of forest nesting species between mature forest and early-successional habitats while ...

From 1995 to 1999, we mist-netted birds in regenerating clearcuts within a primarily forested landscape of West Virginia and Virginia to determine the extent that both resident and migrant birds and their young use this type of early-successional habitat during the post-fledging period.
