Delayed maturity and low reproductive rate make raptors naturally sensitive to high mortality
rates, yet a wide variety of human-related threats negatively affect their population dynamics …

Migratory raptors rarely fly over stretches of water larger than 25 km, although different
species undertake water crossings of varying lengths, depending mainly on their wing …

Billions of migrating birds travel between their breeding and over-wintering areas twice a
year, encountering various environmental conditions along their migration routes. Wind is of …

We describe the detoured migration route of the Oriental honey‐buzzard Pernis
ptilorhyncus, showing differences between autumn and spring migration, using data from 10 …

A growing body of work shows that climate change is the cause of a number of directional
shifts in the spring phenology of migratory birds. However, changes in autumn phenology …

This study provides the first systematic survey of spring and autumn migration of adult
European Honey Buzzards (Pernis apivorus) along the Central-Eastern Mediterranean …

Many species of raptors winter in Africa and breed in central and northern Europe, migrating
north in the spring and south in autumn (Gensbøl 1992, Ferguson-Lees and Christie 2001) …

Afro-Palearctic migrants move between breeding and wintering grounds along flyways
determined by several factors (bird morphology, geography, behavioural adaptations) and …

Variables affecting the choice of migrating European honey buzzards to fly over a flat
highland or to outflank it by flying over steep slopes and deep valleys were tested. Radar …

Water surfaces are natural barriers for raptors mostly using soaring–gliding flight over land
during migration. Among these, the European Honey Buzzard (Pernis apivorus) is a total …
