Negative effects of artificial nest boxes on birds: A review

Artificial nest boxes are placed to attract birds to nest and breed in a specific location, and they are widely used in avian ecology research and in the attraction of insectivorous birds. There is...

Quiet in the nest: The nest environment attenuates song in a grassland songbird

The nest environment may limit the ability of nest-bound birds to hear sounds from the outside world. In vocal learning species, such as humans and songbirds, it is vital for young animals to hear the...

Vultures as a model for testing molecular adaptations of dietary specialization in birds

Vultures are the only obligate scavengers among extant vertebrates. They provide valuable ecological services in ecosystems through removing carcasses, thus preventing the growth of other scavenger...

Achievements, challenges, and recommendations for waterbird conservation in China's coastal wetlands

China's coastal wetlands provide breeding, migration stopover, and wintering habitats for about 230 waterbird species, which is more than a quarter of all waterbirds in the world. Large-scale and high...

Impact of agricultural landscape structure on the patterns of bird species diversity at a regional scale

The loss of bird species diversity is a crucial problem in the European agricultural landscape. Change in the area coverage of major land cover types has been mentioned as one of the main factors responsible...

More than a simple egg: Underlying mechanisms of cold tolerance in avian embryos

Avian embryos, which develop within eggs, exhibit remarkable tolerance to extremely low temperatures. Despite being a common trait among all birds, the mechanisms underlying this cold tolerance in avian...

Systematics of the avian family Alaudidae using multilocus and genomic data

The family Alaudidae, larks, comprises 93–100 species (depending on taxonomy) that are widely distributed across Africa and Eurasia, with single species extending their ranges to North and northernmost...

Phylogenetic definitions for 25 higher-level clade names of birds

Knowledge of the higher-level phylogenetic relationships of birds has grown substantially during the past two decades due to the application of genomic data. However, the nomenclature of higher-level...

Does bird photography affect nest predation and feeding frequency?

Bird photography is a popular and growing form of ecotourism that contributes to the economic growth of local communities, but its disturbance to bird reproduction remains understudied. We worked in...

Population genomic data reveal low genetic diversity, divergence and local adaptation among threatened Reeves's Pheasant (Syrmaticus reevesii)

Population genomic data could provide valuable information for conservation efforts; however, limited studies have been conducted to investigate the genetic status of threatened pheasants. Reeves's...

Diverse foraging strategies of breeding Swinhoe's Storm-petrel in the productive marginal sea of the Northwest Pacific

Understanding the foraging behavior is essential for investigating seabird ecology and conservation, as well as monitoring the well-being of the marine environment. Breeding seabirds adopt diverse foraging...

A crowd-sourced genomic project to assess hybrid content in a rare avian vagrant (Azure Tit Cyanistes cyanus (Pallas, 1770))

The aim of this study was to correlate plumage variation with the amount of genomic hybrid content in hybrids between Azure Tits Cyanistes cyanus (Pallas, 1770) and European Blue Tit Cyanistes caeruleus...

Migration routes and differences in migration strategies of Whooper Swans between spring and autumn

Long-distance migratory birds travel more rapidly in spring than in autumn, as they face temporal breeding constraints. However, several species travel slower in spring owing to environmental influences,...

Fecal DNA metabarcoding reveals the dietary composition of wintering Red-crowned Cranes (Grus japonensis)

Understanding the diet of threatened wildlife is vital for species-specific conservation and habitat management measures. The Red-crowned Crane (Grus japonensis) is a vulnerable bird distributed in...

Morphology and morphometry of two hybridizing buntings at their hybrid zone in northern Iran reveal intermediate and transgressive morphotypes

The closely related Black-headed Bunting (Emberiza melanocephala, a western Palearctic lineage) and Red-headed Bunting (Emberiza bruniceps, an eastern Palearctic lineage) hybridize and replace each...

A test of genetic divergence of a bird existing in the Sichuan Basin and its surrounding mountain ranges

Island ecosystems, serving as natural laboratories, facilitate geographical isolation, ecological specialization, and species divergence. The Sichuan Basin, surrounded by mountain ranges, represents...

Predicting the non-breeding distributions of the two Asian subspecies of Black-tailed Godwit using morphological information

Until recently, Limosa limosa melanuroides was thought to be the only subspecies of Black-tailed Godwit in the East Asian–Australasian Flyway. For this reason, all previous occurrences and counts of...

Comparisons of microstructure and elemental composition of eggshells among wild plover populations

Reproduction investment is a prominent trade-off in life-history theory and is subject to strong selection pressure. The avian eggshell, as a crucial barrier between the bird embryo and the surrounding...

Selecting the best: Interspecific and age-related diet differences among sympatric steppe passerines

Parental food provisioning is crucial for the growth and survival of offspring. Growth rate depends on food quality and food supplied to offspring may differ from what adults use for their own. In the...

Feeding ecology of a highly aerial bird during its long breeding season

Pallid Swifts (Apus pallidus), as other swifts, are birds extremely adapted to an aerial lifestyle, showing unique adaptations that allow them to fly almost continuously. The diet of these non-stopping...

Local and range-wide distribution of song types suggest Ovenbirds (Seiurus aurocapilla) have song neighborhoods but not macro-dialects

The song systems of oscine passerines (songbirds) are complex and diverse. Because songs are used for both mate attraction and territory defense and are therefore important signals for survival and...

Modelling the nesting-habitat of threatened vulture species in the caucasus: An ecosystem approach to formalising environmental factors in species distribution models

Abiotic factors play an important role in species localisation, but biotic and anthropogenic predictors must also be considered in distribution modelling for models to be biologically meaningful. In...
