Meso‐scale avoidance of wind turbines by four raptors at a Kenyan wind farm

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
We fitted Augur Buzzards, African Hawk Eagles, Martial Eagle and Rüppell's Vultures with solar‐powered GPS trackers to study wind turbine avoidance. Meso‐avoidance was seen in all species. Augur Buzzard had the lowest rate at 48.9%, while African Hawk Eagle had the highest at 74.4% within rotor height.

From the brink of extinction to regulation: northern Europe's white‐tailed eagles now face density dependence and climate constraints after rapid population growth

Oikos, Volume 2026, Issue 7, July 2026.
Population growth reflects the combined influence of regulation and density‐independent factors operating through demographic processes. Under exceptional circumstances (e.g. populations recovering from near‐extinction), growth may initially be weakly regulated but typically slows as negative density dependence (NDD) sets in.

Nests in trees are as good as or better than cliffs for two formerly persecuted, primarily cliff nesting eagles in Spain: a cautionary tale in defining the habitat of range‐restricted or threatened species

Wildlife Biology, Volume 2026, Issue 4, July 2026.
In the late‐20th century, golden and Bonelli's eagles suffered population declines on the Iberian Peninsula, partly due to human persecution. Habitat assessments – especially for Bonelli's eagles – always found or assumed strong associations with cliffs that provided nesting sites.
