Comparative studies of egg recognition and rejection between various sympatric hosts
provide insight into the coevolutionary history of the hosts and parasites, as well as the …

Common cuckoos, Cuculus canorus, are brood parasites: they lay their eggs in the nests of
other bird species, and let these hosts incubate their eggs and feed and rear the nestlings …

One of the most effective defenses against avian brood parasitism is the rejection of the
foreign egg from the host's nest. Until recently, most studies have tested whether hosts …

Hosts have evolved a multiplicity of defensive responses against avian brood parasites. One
of them is mobbing behaviour which often includes direct contact attacks. These aggressive …

The two-note call of the male common cuckoo (Cuculus canorus), the so-called “cu-coo”, is
well known to people as a natural and cultural signal. However, the so-called “bubbling” call …

In some populations of the host of brood parasites, more than two parasite eggs may be laid
in a single nest. This phenomenon is known as multiple parasitism, representing a cost to …

Obligate brood parasitic birds have evolved a rare avian strategy for reproduction by laying
eggs in the nests of other species. In doing so, their breeding ranges, but not necessarily …

It is well known that avian brood parasites lay their eggs in the nests of other bird species,
called hosts. It remains less clear, however, just how parasites are able to recognize their …

To avoid mobbing attacks by their hosts during egg laying, some avian brood parasites have
evolved traits to visually and/or acoustically resemble predator (s) of their hosts. Prior work …

Capsule Brood parasitic Common Cuckoo Cuculus canorus chicks hatch earlier than the
nestlings of their Great Reed Warbler Acrocephalus arundinaceus hosts, but hatching …
