Early life conditions influence fledging success and subsequent local recruitment rates in a declining migratory songbird, the Whinchat Saxicola rubetra

Ecology and Evolution, 2023
Life history traits and environmental conditions influence reproductive success in animals, and consequences of these can influence subsequent survival and recruitment into breeding populations.

Cascading carry-over effects of early activity phenotypes in golden eagles [PDF]

Royal Society Open Science
Early-life conditions are often associated with fitness of animals later in life. Although recent studies show that individual characteristics during development affect the formation of early behavioural phenotypes, we have a limited understanding of the

Post-fledging behaviour of juveniles in the Little Owl (Athene noctua) [PDF]

Ornis Fennica, 2013
Before dispersal, social and spatial behaviour in owls has only been briefly studied. We used radio tracking to monitor age-influenced social and spatial behaviour in 10 juvenile Little Owls (Athene noctua) from nests in Northern Jutland, Denmark. On average, the post-fledging dependency period lasted 35 days (n = 6).

Habitat use and characteristics of Connecticut Warbler during the nesting and post-fledging period

, 2020
These data were collected as a part of an effort to study the nesting ecology of Connecticut Warbler (Oporornis agilis). The fledgling_vegetation_data and associated fledgling_vegetation_metadata file contains vegetation survey data that was collected at

Observations of Red-headed Falcon Falco chicquera (Aves: Falconiformes: Falconidae) nest at Keraniganj, Dhaka, Bangladesh, with a focus on post-fledging behavior

Journal of Threatened Taxa, 2015
A nest of Red-headed Falcon Falco chicquera was observed in 2009, beginning with the onset of breeding and continuing on to the next breeding of the pair.

Effects of individual pre-fledging traits and environmental conditions on return patterns in juvenile king penguins. [PDF]

PLoS ONE, 2011
Despite the importance of early life stages in individuals' life history and population dynamics, very few studies have focused on the constraints to which these juvenile traits are subjected.

Quantifying multiple breeding vital rates in two declining grassland songbirds

Avian Conservation and Ecology, 2021
Many studies of reproductive success in North American songbirds have focused on nesting success, while relatively few have evaluated breeding-season adult survival and post-fledging survival.

Spatially explicit analysis of contributions of a regional conservation strategy toward sustaining northern goshawk habitat

Wildlife Society Bulletin, 2013
Setting aside habitat is a common strategy to maintain viable wildlife populations, but underlying assumptions or effectiveness are rarely evaluated. The Tongass National Forest prioritized habitat management for sensitive species in Southeast Alaska's ...

Ovulation order mediates a trade-off between pre-hatching and post-hatching viability in an altricial bird. [PDF]

PLoS ONE, 2008
Simultaneously dependent siblings often compete for parentally provided resources. This competition may lead to mortality, the probability of which may be a function, in part, of the individual offspring's production order.

Patterns of parental care and movement in divided broods of golden‐winged warblers

Journal of Avian Biology, 2022
Post‐fledging brood division is a poorly understood, yet widespread suite of avian behaviours that includes both division of parental care and spatial division of a brood. For most species, the differences in parental care between adult males and females
