Nestling testosterone is associated with begging behaviour and fledging success in the pied flycatcher, Ficedula hypoleuca.
Animal signals are hypothesized to be costly in order to honestly reflect individual quality. Offspring solicitation signals given by nestling birds are thought to have evolved to advertise either need or individual quality. We tested the potential role of testosterone (T) in controlling the intensity of these signals by measuring begging behaviour as: (i) duration of the begging display and (i...
متن کاملPrehatching maternal investment and offspring immunity in the pied flycatcher (Ficedula hypoleuca).
Maternal investment in offspring immunity via egg quality may be an adaptive evolutionary strategy shaped by natural selection. We investigated how maternal investment in eggs can influence offspring immunity by conducting two experiments. First, we manipulated foraging performance of the mothers before egg laying by attaching a small weight to their back feathers. During the nestling period, w...
متن کاملHigh Prevalence of Hematozoa in Nestlings of a Passerine Species, the Pied Flycatcher (Ficedula Hypoleuca)
While this may be true in many passerines, mainly ground-nesting species with short fledgling periods, we show here that prevalences may be detected as early as 13 days of age in a cavity-nesting passerine. Prevalences and intensities of hematozoa in nestling birds may merit further study, as both parameters are relatively easy to quantify in smears of peripheral blood in bird species such as t...
متن کاملDegradation of song in a species using nesting holes: the Pied Flycatcher Ficedula hypoleuca.
The habitat, but also the nest hole of a hole-nesting species, will degrade the song during transmission. We investigated how the sounds degrade in a sound transmission experiment with the song of the Pied Flycatcher Ficedula hypoleuca (Muscicapidae). Ten different song elements were transmitted to microphones placed inside and outside a nest box. On average, song degradation was much greater i...
متن کاملResponses to Reduced Industrial Metal Emissions: An Ecotoxicological Study on Pied Flycatcher (Ficedula hypoleuca, Aves)
Metals have been used by humans for thousands of years, and this has resulted in increased concentrations in the biosphere. The environment around pointsources, such as mines and smelters, are of particular concern, as metals may accumulate to high concentrations, and potentially reach levels toxic to the local flora and fauna. This thesis focuses on the effects on pied flycatcher populations o...
