Abstract Disentangling the relative influence of different anthropogenic pressures, landscape composition and biotic conditions on birdsong from species to community levels is challenging. On basis a field survey conducted breeding bird in France, we measured such factors timing birdsongs along an urbanization gradient. First, found that can be sorted according time song indices, early singing are also those with largest eye sizes. For given species, birds sing earlier during shorter period areas densely built, submitted high artificial lights, traffic noise, hosting lowest conspecific abundances. At level, urbanization, especially highly built lit areas, leads reassembly promoting late for short periods. Finally, lights noise promote higher temporal turnover lower nestedness dawn chorus at level: tend succession rather than polyphony. Our results suggest full chorus, gathering almost all together same has thus disappeared most urbanized areas.

La bioacústica, o el estudio de los sonidos que producen animales, es una herramienta ha sido ampliamente usada en las aves, con un incremento número estudios la aplican últimas décadas por su carácter poco invasivo y relativo bajo costo. Aquí presentamos revisión sistemática investigaciones sobre bioacústica aplicada a ornitología colombiana últimos 22 años, identificando principales temáticas se abordan (e.g., taxonomía, inventarios monitoreos, comportamiento, ecología), exploramos historia desarrollo esta herramienta, impacto colombiana. Enfatizamos importancia del evolutivo comunicación aves papel delimitación e identificación especies, técnicas monitoreo acústico, ecología paisaje urbanización, esclarecemos algunos aspectos neurobiológicos aprendizaje vocalizaciones. También destacamos valor colecciones biológicas regional abordamos problemática limitaciones sesgos investigación científica han subestimado comportamientos estudiados como canto hembras.

Steadily increasing human population is changing the environment in many ways. One of most disturbing impacts development anthropogenic noise pollution connected to ever-growing traffic intensity. The road network can have both positive and negative effects on biodiversity populations. Many bird species use acoustic communication establish maintain their territories for intra-pair adult–young communication. Noise impact negatively breeding success biorhythm if this masked by individuals must adjust singing activity. Yellowhammer ( Emberiza citrinella ) a common agricultural landscapes whose declining due intensification. It found also habitats near highways with forest steppe-like characteristics, where it affected high levels pollution. This study aimed determine how adapts from highway adjusting its influence locality type, immediate long-term average total length song sequences birdsong, number recorded during second hour after sunrise were evaluated study. Our results showed that Yellowhammer’s activity changed localities close compared landscape. With intensity highways, duration was decreasing. present led later onset dawn chorus decreasing strophe passing vehicles. Furthermore, landscape, increased distance nearest road.

Artificial light at night (ALAN) and noise pollution are two important stressors associated with urbanisation that can have a profound impact on animal behaviour physiology, potentially disrupting biological rhythms. Although the influence of ALAN daily activity patterns songbirds has been clearly demonstrated, studies often focus males, few examined females not included potential males female patterns.

Urbanization is expanding rapidly worldwide, and brings additional selection pressure on animals. The song differences between urban rural songbirds have been widely verified, but the effects of morphological variation long-settled birds poorly explored. Here, we investigated distribution a common resident songbird-the oriental magpie-robin (Copsychus saularis) three morphology types (i.e., park, low-rise residential area, high-rise area). results indicated that population density in areas was significantly higher than parks, while it lowest areas. Males had greater length, syllable numbers, frequency bandwidth, diversity those parks. were mainly related to habitat types, independent singing height perch type. Our findings suggest may provide preferred post sites for magpie-robin, which well-adapted building morphology, rejects emerging buildings.
