A chick of the Horsfield's hawk cuckoo Cuculus fugax has a vivid yellow skin patch on each wing-bend, which is very similar in colour to its own gape. Almost every time a host parent delivers food, the chick explicitly displays the wing-patch by[...]

Male eastern bluebirds Sialia sialis have striking ultraviolet (UV)-blue coloration on their heads, backs, rumps, wings, and tails and bold chestnut coloration on their breasts. These colored areas are ornaments that correlate with pairing date [...]

An increasing number of studies have demonstrated that brood sex ratios are frequently unequal, but the proximate mechanisms underlying this deviation are largely unknown. In the current study we analysed deviation from expected 1:1 sex ratio am[...]

Parent-offspring recognition systems are used in bird colonies to avoid misdirected parental care. In penguins, where the risk of confusion is particularly high, recognition is achieved by acoustic signals that constitute highly efficient vocal [...]

In animals that produce few offspring during their lifetime, the ability to raise high-quality offspring through the provision of parental care is particularly important for individual fitness. In this paper, we use repeatability analysis of dat[...]

Seasonal decline in breeding success limits fitness in many bird species nesting in the temperate, boreal and arctic zones. Factors affecting this decline, especially if the decline is reduced, can thus have significant ecological and evolutiona[...]

Data on nest success and brood productivity of three ground-nesting, three canopy-nesting and four hole-nesting (non-excavator) passerines were gathered in a primeval lowland temperate forest (Bialowieza National Park, E Poland). Natural holes w[...]

During the last 40 years, few species of African birds have undergone more taxonomic revision than the olive thrush Turdus olivaceus. This is due to disagreement on how to partition the striking phenotypic variation among allopatric populations.[...]

Climate change has advanced the breeding dates of many bird species, but for few species we know whether this advancement is sufficient to track the advancement of the underlying levels of the food chain. For the long-distance migratory pied fly[...]

Factors determining clutch size of birds have long been the central issue in studies in life histories. It is assumed that the configuration of brood patches could limit the maximum clutch size. To test this hypothesis we manipulated clutch size[...]

The division of labour in parental care between the two sexes varies between and within species. In birds, parents have been shown to invest more into egg production and nestling care when paired with an attractive rather than an unattractive ma[...]

The New Zealand stitchbird or hihi Notiomystis cincta is unique in that it has two distinct mating positions, in addition to the male standing on the female's back, as is seen in all other birds, it also copulates face-to-face. In this study, 43[...]

We investigated whether exposure to heavy metal pollution affected the immune function of individuals in a free living population of a small insectivorous passerine bird, the pied flycatcher Ficedula hypoleuca. We measured humoral immune respons[...]
