- ... In many bird species, parents usually feed the first nestling that starts to beg before its nest‐mates. The pressure to avoid missed feeds could trigger nestlings to perform in erroneous begging in absence of parents, which has the same costs as begging in the presence of parents but without any reward. So, nestlings should try to minimize both erroneous begging and missed feeds simultaneously. Th ...

- ... One of the most important defensive host traits against brood parasitism is the detection and ejection of parasitic eggs from their nests. Here, we explore the possible role of olfaction in this defensive behaviour. We performed egg‐recognition tests in magpie Pica pica nests with model eggs resembling those of parasitic great spotted cuckoos Clamator glandarius. In one of the experiment, experime ...

- ... The assessment of plumage colouration has become a common procedure in many ornithological studies, especially after the discovery of differences between avian and human visual systems, namely the avian ability to perceive ultraviolet wavelengths. There are many techniques available for plumage colour assessment. Nevertheless, unidirectional reflectance spectrometry seems actually to be the method ...
