Open AccessIs syllable repetitions a song parameter important for male-male interactions in Eurasian reed warbler (Acrocephalus scirpaceus)?
Song complexity has been identified as one song characteristic important in female choice, whereas its role in male-male interactions is less clear and not much is known which song characteristics are specific...

Slow song syllable rates provoke stronger male territorial responses in Eurasian Reed Warblers (Acrocephalus scirpaceus)
In birds, male song is mainly driven by sexual selection, whereby several song characteristics have been demonstrated to be important. In this context, the number of syllables produced per time unit (syllable ...

Behavioural response of Eurasian Blackcaps to acoustically simulated conspecific and heterospecific male intruders
Interspecific territoriality can frequently be observed in the animal kingdom, including birds. One important factor driving the degree of interspecific territoriality is competition for resources. Other influ...

The effect of the ectoparasite Carnus hemapterus on immune defence, condition, and health of nestling European Bee-eaters
One way that parasites influence host survival and fitness is by competing with their hosts for resources that would otherwise be used for growth and immune system development. Thus resource availability, infl...

Vegetation type variation in marsh habitats: does it affect nest site selection, reproductive success, and maternal investment in Reed Warblers?
Habitat choice may have an important impact on survival and fitness of an individual. Besides an individual’s intrinsic features, such as resource-holding potential, experience, age, and habitat characteristic...

Song complexity in male marsh warblers: does it reflect male quality?
Male song is known to be important in the mate choice of birds, as different song features reflect different traits of the singer. The reason why song complexity, in this context, should reflect the quality of...

Distinct colour morphs in nestling European Bee-eaters Merops apiaster: is there an adaptive value?
In a few bird species, dimorphism already exists in nestling and juvenile plumage coloration and these colour morphs are often attributable to different sexes. In this study we detected variation in nestling c...

Food preferences and mound-building behaviour of the mound-building mice Mus spicilegus
Optimal foraging strategies and food choice are influenced by various factors, e.g. availability, size and caloric content of the food type and predation risk. However, food choice criteria may change when foo...
