Migration and stopover use by GPS‐tracked adult Ospreys (Pandion haliaetus) from Germany

open access: yesIbis, Volume 167, Issue 3, Page 646-659, July 2025.
The ability to meet the high energetic costs of long‐distance migration can be a key factor in the survival of individual birds. The use of stopovers, where individuals pause to rest and feed, is a common strategy in many migratory bird species. In this study, we explore migration timing of 28 satellite‐tracked (17 GPS and 11 Argos) adult migratory ...

Первый случай гнездования скопы на опоре высоковольтной ЛЭП в Саяне, Россия

open access: yesПернатые хищники и их охрана, 2017
В ходе маршрута вдоль р. Бол. Он 22 июня2016 г. было обнаружено жилое гнездо скопы, располагавшееся в высотном диапазоне1321 м. над уровнем моря. Это гнездо птицы устроили нетрадиционно – на горизонтальной перекладине металлической опоры высоковольтной ...

О взаимоотношениях скопы и орлана-белохвоста в Северной Беларуси

open access: yesПернатые хищники и их охрана, 2018
В свете событий последних десятилетий по увеличению численности орлана-белохво-ста (Haliaeetus albicilla) во многих европейских странах, естественно возник вопрос, а как поведёт себя в этих условиях скопа (Pandion haliaetus), населяющая, в основном ...

Stick supply to nests by cliff-nesting raptors as an evolutionary load of past tree-nesting

open access: yesIdeas in Ecology and Evolution, 2019
The supply of sticks to cliff nests by many European raptors has been explained only as a functional means of decreasing ectoparasite loads in nests and for signalling nest occupancy.

Effects of wind farms on raptors: A systematic review of the current knowledge and the potential solutions to mitigate negative impacts

open access: yesAnimal Conservation, Volume 28, Issue 3, Page 334-352, June 2025.
Our review of 195 studies highlights the consensus on raptors’ avoidance behavior and population decline post‐wind farm installation, emphasizing the significant risks posed by mountaintop wind farms to soaring raptors. Adult raptor mortality, particularly among endangered species, and the elevated collision risks faced by young individuals underscore ...

A Trophic and Non‐Trophic Seasonal Interaction Network Reveals Potential Management Units and Functionally Important Species

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 1, January 2025.
ABSTRACT Aim Understanding the organisation of the wide variety of ecological interactions is crucial to advancing our understanding and management of real ecosystems. We aimed to compile a ‘complete’ network of tetrapod trophic and non‐trophic interactions for the entire North American boreal forest biome that could be analysed to gain insights into ...

Hunting patterns and success of an osprey (Pandion haliaetus) population at Magdalena Bay, Baja California Sur, Mexico

open access: yesCiencias Marinas, 2007
In late autumn 2004 we studied the effect of water surface condition, wind speed, and tidal status on the hunting patterns (flapping, gliding, hovering) and hunting success of the osprey population at Magdalena Bay, Baja California Sur, Mexico.

Migration mortality in birds

open access: yesIbis, Volume 167, Issue 1, Page 106-123, January 2025.
Bird migration is one of the greatest wildlife spectacles, producing massive global changes in the distributions of birds twice each year. To understand the evolution of this phenomenon, it is important to know the costs of these journeys in terms of the mortality they impose.

Скопа в Алтае-Саянском регионе, Россия

open access: yesПернатые хищники и их охрана, 2018
Для Алтае-Саянского региона численность скопы к 2005 г. оценивалась в 360–380 гнездящихся пар, а к 2015 г. – около 400 пар за счёт лучшей обследованности территории региона.
