Syntax of complex bird song in the large-billed reed warbler (Acrocephalus orinus)
Abstract Among songbirds there are species with rich and variable repertoires and very complex sequences of sounds that are hard to analyse. Here, we investigate repertoire and syntax organization inExpand

Phylogeny reconstruction of the yellowhammer (Emberiza citrinella) and pine bunting (Emberiza leucocephala) based on song and morphological characters
The yellowhammer and pine bunting represent a quite rare case of mass hybridization in a broad secondary contact zone. Previously, it was shown that the two forms did not differ by mitochondrial DNAExpand

Variations of space use in males of the banded demoiselle (Calopteryx splendens, Zygoptera, Odonata): Alternative tactics or an age-dependent trend?
Two spatial tactics are usually distinguished in males of Calopteryx damselflies: territorial and nonterritorial. These tactics are believed to underlie two alternative condition-dependentExpand

Singing of Claudia’s Leaf-warbler (Phylloscopus claudiae) in aggressive contexts: role of song rate, song type diversity and song type transitional pattern
AbstractIn many songbirds, males vary certain aspects of their singing behavior when engaged in territorial interactions. Song rate, song type switching rate, song matching, song overlapping, and theExpand

Behavioral Ecology of Elliot’s Laughingthrush (Trochalopteron (Garrulax) elliotii; Timaliidae): I. Breeding Biology and Social Behavior
Babblers (Timaliidae s. l.) are a diverse group of passerine birds distributed mainly in Asia. The behavior and vocalization of most babbler species are poorly known. We provide the first descriptionExpand

Behavioral Ecology of Elliot’s Laughingthrush (Trochalopteron (Garrulax) elliotii, Timaliidae, Aves): 2. Vocal Repertoire
Our work is the first study on the vocal repertoire of one of the babbler species, Elliot’s laughingthrush. Field studies were carried out in Hupingshan Nature Reserve, Hunan Province, China. ThereExpand

Behavior of males in a reproductive aggregation of the banded demoiselle Calopteryx splendens (Insecta, Odonata)
The view according to which damselfly males practice two alternative reproductive tactics of access to females is critically discussed. It is widely accepted that some males (“territorial” ones) haveExpand

Differences in song repertoire organization in two leaf warbler species (Phylloscopidae), the large-billed leaf warbler (Phylloscopus magnirostris) and the sulfur-breasted leaf warbler (Phylloscopus
Distinct song types that constitute the song repertoire can be identified in the singing of males of many passerine bird species. Song repertoires and the organization of singing in two ChineseExpand
