Behavioural ecology by definition of its founding 'Tinbergian framework'is an integrative
field, however, it lags behind in incorporating genomic methods.'Finding the gene/s for a …

Obligate brood parasitism is a peculiar behaviour found in some bird species. The costs for
their hosts can be high, generating selection for active defence strategies including foreign …

Intraspecific nest parasitism is a phenomenon that attracts the attention of biologists since it
helps in saving the endangered species such as Slender Billed Gull. The problem comes …

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 …

Multiple raptors show juvenile plumage that is substantially different from that of their
parents. Here, we test the prediction that the colouration of the juvenile northern goshawk …

Animal and plant colouration presents a striking dimension of phenotypic variation, the study
of which has driven general advances in ecology, evolution, and animal behaviour …

The phenomenon of intraspecific nest parasitism is of a great interest to biologists because it
helps in the conservation of critically endangered birds like the Slender-billed Gull. Indeed …

Highlights•Cuckoo egg-laying areas varied in size and overlapped to a large extent.•Cuckoo
egg-laying areas were smaller when density of host nests was higher.•Size and location of …

In oviparous animals, egg morphology is considered an aspect of the extended phenotype
of the laying mother and, thus, can be directly assessed for consistency both within and …

When host nests are scarce, avian brood parasites would benefit from behaviours that
increase the availability of suitable nests. Several studies reported ejection of host nestlings …
