Postfledging movements and site persistence of Saxicola rubetra in the abandoned fields in Russky Sever National Park (north of European Russia)

open access: yesNature Conservation Research: Заповедная наука
The post-fledging period, usually defined as the time between when a bird fledges and disperses outside the natal site, is an important critical stage in the life cycle of open-nesting passerines.

First breeding of lesser kestrel Falco naumanni in Campania

open access: yesAvocetta
The Lesser Kestrel (Falco naumanni) is a small falcon whose Italian breeding range is currently expanding. Summer records from Campania have been considered to refer to wandering individuals from breeding colonies in nearby Puglia and Basilicata.

When and why to give shorebirds a head start

open access: yesConservation Biology, EarlyView.
Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

Nestling erythrocyte resistance to oxidative stress predicts fledging success but not local recruitment in a wild bird

open access: yes, 2013
Stressful conditions experienced by individuals during their early development have long-term consequences on various life-history traits such as survival until first reproduction.

The many prices of war and occupation: Black markets and the cost‐of‐living index in France, 1938–1949

open access: yesThe Economic History Review, EarlyView.
Abstract When studying French prices between 1938 and 1949, economists and historians face a paradox: whilst a vast black market shaped daily life, official indices recorded only state‐controlled prices. This article addresses the issue by introducing a new consumer price index that incorporates both official and black market prices.

Kant's Solution to the Trilemma of Concept Formation

open access: yesEuropean Journal of Philosophy, EarlyView.
Abstract According to a widespread assumption, Kant's logical account of concept formation starts with comparison, where the latter involves concepts. On this assumption, the formation of a concept presupposes other concepts, so that the argument is threatened either by circularity, regress, or break‐off.

Contributions of Positive Social Interactions to Vocal Learning and Social Cohesion

open access: yesEthology, EarlyView.
Birdsong produced in non‐breeding flocks is shaped by a dynamic interplay between intrinsic reward and social feedback. Studies in cowbirds and starlings suggest that positive affective states and opioid‐mediated reward promote song practice, while responses from flock mates, potentially reinforced by dopaminergic mechanisms, refine species‐typical ...

When Swallows postpone the south: first recorded November fledging of Hirundo rustica in Italy

open access: yesRivista Italiana di Ornitologia - Research in Ornithology
The Barn Swallow (Hirundo rustica) is a long-distance migratory species whose breeding season in Europe occurs between March and August. However, on November 4th, 2024, a late breeding attempt was documented in Acquanegra sul Chiese (Mantua, Italy). The

How the importance of survival estimates in estimating Whinchat population dynamics depends on the scale of migratory connectivity and site fidelity [PDF]

open access: yes, 2015
Accurate monitoring of whinchat population dynamics requires accurate estimates of breeding season survival and productivity, non-breeding survival and site fidelity (dispersal, immigration and emmigration).
