Wind energy production has expanded to meet climate change mitigation goals, but
negative impacts of wind turbines have been reported on wildlife. Soaring birds are among …

The aerosphere is utilized by billions of birds, moving for different reasons and from short to
great distances spanning tens of thousands of kilometres. The aerosphere, however, is also …

Increased human-induced environmental changes and global warming alter bird migration
timing and routes. Recently, many Holarctic species, including white storks, Ciconia ciconia …

Disentangling individual-and population-level variation in migratory movements is
necessary for understanding migration at the species level. However, very few studies have …

Early arrival at breeding grounds is of prime importance for migrating birds as it is known to
enhance breeding success. Adults, males and higher quality individuals typically arrive …

Large bodies of water represent major obstacles for the migration of soaring birds because
thermal updrafts are absent or weak over water. Soaring birds are known to time their water …

Site selection bias can occur when researchers monitor animals at sites of great abundance,
occupancy or quality. The prevailing heuristic is therefore that ecologists should never select …

Open landfills seem to be playing an increasing role as target feeding areas for several
species, not only in their breeding areas or during the winter, but also during the migration …

Estimating animal populations is essential for conservation. Censusing large congregations
is especially important since these are priorities for protection, but efficiently counting …

Wind energy production has expanded as an alternative to carbon emitting fossil fuels, but is
causing impacts on wildlife that need to be addressed. Soaring birds show concerning rates …
