ABSTRACT A growing body of work suggests that breeding birds have a significant capacity
to assess and respond, over ecological time, to changes in the risk of predation to both …

We review the ecological rationale behind the potential compatibility between top predators
and biodiversity conservation, and examine their effectiveness as surrogate species …

Raptors provide critical ecosystem services, yet there is currently no systematic, global
synthesis of their conservation status or threats. We review the International Union for the …

The author shares some lessons learned from a lifetime of working with and thinking about
groups. Three types of groups are described, including the impact they have on the …

Decision making can be facilitated by observing other individuals faced with the same or
similar problem, and recent research suggests that this social information use is a …

Mixed‐species animal groups (MSGs) are widely acknowledged to increase predator
avoidance and foraging efficiency, among other benefits, and thereby increase participants' …

How can the stunning diversity of social systems and behaviours seen in nature be
explained? Drawing on social evolution theory, experimental evidence and studies …

Pioneer of systematic surveys of raptors, Derek was a good friend and mentor to many
people who have studied these birds. Through his work on pesticides and protected areas …

Exploiting the nest defence behaviour of another relatively aggressive species is one of the
most unusual amongst a great diversity of strategies used by animals to evade predation …

Summary 1 Intraguild predation (IGP) has been studied extensively in predatory fish,
amphibians and mammals, but less so in top avian predators. We studied the impact of IGP …
