Several songbird species use two singing modes, which are functionally different. The first mode is preferentially used at the beginning of the breeding cycle, and serves to attract females, while the second mode is used later in the season as well a

Birdsong is one of the most complex signals in the animal world, as it may consist of many different sounds grouped according to certain rules. Singing acts as a distant signal, indicating, e.g., the species and gender identity of the singer. However

In most passerine species, an individual bird sings multiple song types to be combined into non-random song sequences. Because of this non-randomness, stereotype sequences of several or even dozens of song types appear in the vocalization of some spe

Performance of vocal signals, such as birdsong, may be a subject to trade-offs among acoustic traits that limit the signal outcomes. Trilled songs in which syllables are repeated in rapid successio...

Previously, in male Greenfinch, we have described ultradian rhythms of body temperature with periods of 3–6, 8–10, 12–20, and 40–60 min. There are individual variations in this rhythmicity. Rhythms with a period of 3–7 min are more characte

In many songbird species, individuals sing multiple song types, some of which are shared between neighbours. Individuals may also share transitions between different song types, which leads to shar...

Complex song has been described in several songbird species, but few studies have dealt with intra-individual variability in song bout organization. In this study, we compared the song bouts of 19 Radde’s warbler males recorded either on three (11
