Despite the fact that many animals live in groups, there is still no clear consensus about the
ecological or evolutionary mechanisms underlying colonial living. Recently, research has …

Many animals, including humans, acquire valuable skills and knowledge by copying others.
Scientists refer to this as social learning. It is one of the most exciting and rapidly developing …

Predators have profound effects on prey behavior and some adult brood parasites use
predator resemblance to exploit the antipredator defenses of their hosts. Clarifying host …

Interactions between avian brood parasites, such as common cuckoos (Cuculus canorus),
and their hosts are one of the best‐studied examples of the coevolutionary arms race …

Interactions between avian hosts and brood parasites can provide a model for how animals
adapt to a changing world. Reed warbler (Acrocephalus scirpaceus) hosts employ costly …

As the frontline defense against avian brood parasitism, nest defense is important in
reducing nest parasitism and increasing host fitness. However, systematic studies on its …

Background Many potential hosts of social parasites recognize and reject foreign intruders,
and reduce or altogether escape the negative impacts of parasitism. The ontogenetic basis …

Background Co-evolutionary struggles between dangerous enemies (eg, brood parasites)
and their victims (hosts) lead to the emergence of sophisticated adaptations and counter …

Avian nest defence, which is expected to serve both antiparasite and antipredator functions,
may benefit or be detrimental to birds, although selective forces that potentially operate on …

Referential alarm calls that denote specific types of dangers are common across diverse
vertebrate lineages. Different alarm calls can indicate a variety of threats, which often require …
