Use of evergreen and deciduous plants by nocturnal-roosting birds: A case study in Beijing

With continually increasing urbanization, the land cover in urban areas continues to change, resulting in the loss of biodiversity. Birds are highly sensitive to changes in habitat. Most forest birds...

Shallow sub-lakes are essential for sustaining the successful wintering of waterbirds in Poyang Lake, China

For migratory waterbirds, the quality of wintering habitat is related to spring migration and successful breeding in the next year. The availability of food resources in the habitat is critical and...

Development and parentage analysis of SNP markers for Chestnut-vented Nuthatch (Sitta nagaensis) based on ddRAD-seq data

Extra-pair paternity (EPP) is commonly found in socially monogamous birds, especially in small passerine birds, and there are interspecific and intraspecific variations in the extent of EPP. The Chestnut-vented...

Annual variation of adult survival of a south-temperate House Wren population in Argentina

Identifying factors affecting the survival of individuals is essential for understanding the evolution of life-history traits and population dynamics. Despite numerous studies on this subject in north-temperate...

The effect of Common Cuckoo parasitism on the annual productivity of a host population

Avian interspecific brood parasitism is an excellent system for studying coevolutionary processes in nature because brood parasites directly affect host reproductive success. Most research on avian...

Structural effects of reedbed grazing and its cessation on reed-nesting songbird densities

Reedbeds are crucial breeding habitats for vulnerable songbird species. Irrespective of their protection status, these habitats may be threatened by organic matter accumulation, progressively leading...

Detour for the inexperienced? Migration count data suggest mostly juvenile Greater Spotted Eagles appear in coastal peninsulas in China

Soaring bird migration often relies on suitable terrain and airflow; therefore, route selection is vital for successful migration. While age and experience have been identified as key factor influencing...

Inbreeding and genetic load in a pair of sibling grouse species: Tetrastes sewersowi and T. bonasia

Genetic load and inbreeding are recognized as important factors to be considered in conservation programs. Elevated levels of both can increase the risk of population extinction by negatively impacting...

Integrating host biological and ecological variables to predict probability of haemosporidian infection in raptors

Variations in host traits that influence their exposure and susceptibility may impact probability of vector-transmitted diseases. Therefore, identifying the predictors of infection probability is necessary...

Weak influence of natural vegetation in urban green spaces compared to agricultural ecosystems on House Martin populations: Insights from nationwide citizen science data in the Czech Republic

The House Martin (Delichon urbicum) is a common farmland bird species in the European landscape, yet its population numbers are currently in decline. However, it is not yet sufficiently explained why...

The influence of wing morphology upon intraspecific divergence in birds: A global study of subspecies richness

Since the time of Darwin, subspecies have been recognized as an initial stage in the evolution of species. However, the impact of dispersal on subspecies richness in birds globally has received little...

Changes in the adult sex ratio of six duck species breeding populations over two decades

Despite all efforts, long-term changes in the adult sex ratios of breeding duck populations are still unclear; this uncertainty is especially true for male-bias populations, which are often under the...

Nest decoration: Black feathers prevent Crested Mynas from nest usurpation

Nests are important structures for birds to raise their offspring and for signaling. Many birds incorporate feathers into the nest, since feathers were traditionally thought to serve the function of...

Individual consistency in spatiotemporal characteristics of migratory Whimbrels in the East Asian–Australasian Flyway

Many migratory birds exhibit interannual consistency in migration schedules, routes and stopover sites. Detecting the interannual consistency in spatiotemporal characteristics helps understand the maintenance...

Oriental Reed Warblers do not abandon Common Cuckoo chicks during prolonged nestling periods

The Oriental Reed Warbler (Acrocephalus orientalis) is one of the most commonly used hosts for the parasitic Common Cuckoo (Cuculus canorus). However, as hosts that feed unrelated parasitic nestlings...

Using non-destructive sampling to evaluate the population genomic status of captive Brown Eared Pheasants

Evaluating the genetic status of threatened species is an essential task in conservation genetics. However, the genetic status of threatened species has been mostly evaluated through techniques that...

Avian malaria, haematocrit, and body condition in invasive wetland passerines settled in southwestern Spain

Avian malaria and related haemosporidian parasites can negatively impact fitness in many songbirds. Research on the malaria infection and its physiological costs on their avian hosts is heavily skewed...

Vocal repertoire of Azure-winged Magpies (Cyanopica cyanus): A context-associated communication system

Signals within animals’ vocal communication are considered functional referential and context-specific. Even in the absence of the context, receivers are expected to acquire the information of calls...

Habitat-dependent breeding biology of the Blue Tit (Cyanistes caeruleus) across a continuous and heterogeneous Mediterranean woodland

Mediterranean woodland environments are characterised by high spatial and temporal heterogeneity, which means the inhabiting species face a wide variety of selective pressures. Species may respond differently...

Egg rejection and egg recognition mechanism in a Chinese Azure-winged Magpie (Cyanopica cyanus) population

Recognition and rejection of foreign eggs are effective defense of hosts against brood parasitism. However, brood parasitism can impose various selection pressures on different geographic populations...

Altitudinal migration behavior patterns of birds on the eastern slope of Mt. Gongga, China

Many bird species in montane regions exhibit altitudinal migration behavior; however, altitudinal migration of birds is still understudied, especially in Asia. Mt. Gongga (7556 ​m) is the highest peak...

Data reliability of the emerging citizen science in the Greater Bay Area of China

The potential of citizen science projects in research has been increasingly acknowledged, but the substantial engagement of these projects is restricted by the quality of citizen science data. Based...

Physiological strategies of moult-migrating Black-necked Grebes (Podiceps nigricollis) in a polluted staging site according to blood chemistry

After breeding, Black-necked Grebes (Podiceps nigricollis) perform a moult-migration to autumn hypersaline staging sites, where they moult the flight feathers and forage on superabundant brine shrimp...

Phylogeography and diversification of Oriental weaverbirds (Ploceus spp.): A gradual increase of eurytopy

Weaverbirds are a speciose group of colorful passerines inhabiting the Old World Tropics. Nevertheless, the Oriental weaverbirds (Ploceus spp.), widespread across southern Asia, are much less diverse...
