Post-fledging survival of Tengmalm’s owl offspring in boreal forests: Interactive effects of varying dynamics of main prey and habitat composition

Frontiers in Ecology and Evolution, 2023
The knowledge about the mortality rate of offspring is crucial for estimating bird population dynamics and conserving species with declining populations.

Earlier hatching date rather than chick phenotypic quality enhances first-year survival in the black-headed gull [PDF]

Frontiers in Zoology
Background Favourable conditions experienced during early ontogeny are expected to positively influence individual performance at later stages of the life cycle and determine lifetime fitness.

Sibling cooperation in boreal owls during the post-fledging dependence period [PDF]

BMC Biology
Background Many vertebrates develop in the company of their siblings, a social context that profoundly influences their life histories and phenotypes.

From fledging to independence: Post-fledging movements and space use of the Crested Ibis (Nipponia nippon)

Avian Research
The post-fledging period, extending from fledging to independence, is a crucial life stage characterized by high mortality due to fledglings' limited mobility and inexperience.

Breeding Biology of the Twite Linaria flavirostris in the North-Eastern Qinghai–Tibet Plateau, with Special Reference to Life-History Variation Across Latitudes and Altitudes [PDF]

Animals
In 2024 and 2025, researchers investigated the breeding ecology of the Twite Linaria flavirostris in riparian shrubland habitats at an elevation of 3400 m in the northeastern Qinghai–Tibet Plateau.

Satellite tracking reveals the home range and movement ecology across the annual cycle of a 32 g songbird [PDF]

Movement Ecology
Background Understanding movement ecology across life-history stages is critical for conserving declining migratory species. The Bobolink (Dolichonyx oryzivorus), a grassland songbird, exhibits complex spatial behaviors shaped by annual cycle stage ...

The effect of local and landscape-level characteristics on the abundance of forest birds in early-successional habitats during the post-fledging season in western Massachusetts. [PDF]

PLoS ONE, 2014
Many species of mature forest-nesting birds ("forest birds") undergo a pronounced shift in habitat use during the post-fledging period and move from their forest nesting sites into areas of early-successional vegetation.

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

Journal of Field Ornithology, 2023
Widespread declines in breeding bird populations have been documented across North America since the 1970s, and concerns about loss of avian biodiversity are growing.

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

Avian 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 ...
