Detectability matters: conspicuous nestling mouth colours make prey transfer easier for parents in a cavity nesting bird.
An often underappreciated function of signals is to notify receivers of the presence and position of senders. The colours that ornament the mouthparts of nestling birds, for example, have been hypothesized to evolve via selective pressure generated by parents' inability to efficiently detect and feed nestlings without such visually conspicuous targets. This proposed mechanism has primarily been...
متن کاملSmall passerines can discriminate ultraviolet surface colours.
Hollow-dwelling passerine birds were tested for UV surface colour discrimination by using the instinct to bring food to nestlings that makes a bird search for the nest under changing conditions. The experiments were carried out on breeding pairs of pied flycatcher (Muscicapa hypoleuca), great tit (Parus major) and tree sparrow (Passer montanus) in the wild by the method of alternative choice of...
متن کاملYolk androgens and begging behaviour in black-headed gull chicks: an experimental field study
Black-headed gulls, Larus ridibundus, produce clutches of three eggs, which contain high levels of maternal androgens in the yolk. These levels increase with laying order and the eggs hatch asynchronously. Experiments have supported the hypothesis that this within-clutch variation in maternal androgens mitigates the disadvantage of last-hatched chicks in sibling competition, by enhancing embryo...
متن کاملOn the oxidative cost of begging: antioxidants enhance vocalizations in gull chicks
Offspring solicit food to their parents by begging displays, which are important in the parent–offspring communication. Most theoretical approximations on this behavior have centered on the view of begging as an honest signal of need or as a form of scramble competition for resources. In both signaling models, costly begging is necessary to stabilize the begging strategy at equilibrium. Neverth...
متن کاملThe ultraviolet colours and dust attenuation of Lyman-break galaxies
Using GALFORM, a semi-analytical model of galaxy formation in the cold dark matter cosmology, we study the rest-frame ultraviolet (UV) colours of Lyman-break galaxies (LBGs) in the redshift range 2.5 ≤ z ≤ 10. As the impact of dust on UV luminosity can be dramatic, our model includes a self-consistent computation of dust attenuation based on a radiative transfer model. We find that intrinsicall...
