Beyond accuracy: AI-based bird behavior automated recognition toward ecological understanding
Understanding bird behavior is fundamental to avian ecology, conservation, and evolutionary biology. Advances in sensing technologies and artificial intelligence (AI) have enabled automated detection of avian activities at unprecedented scales. However, a critical limitation is emerging for current…

Vocal learning in juvenile and adult Budgerigars
Vocal production learning is known to occur in a limited number of non-human taxa. Among birds, songbirds such as Zebra Finches ( Taeniopygia guttata ) are often studied as closed-ended learners, acquiring their vocal repertoire only during an early sensitive period, whereas open-ended learners…

Distribution of songbird migrants in autumn in the arid belt of Central Eurasia: West vs. East
The arid belt of Central Eurasia is a formidable obstacle for annual migratory movements of songbirds. Most birds that breed in the forests of Eurasia and spend their winter in the subtropics and tropics of the Old World have to manage this ecological barrier. Some of them cross it directly…

Variation in avian haemosporidian infection patterns in Daurian Redstarts (Phoenicurus auroreus) across eastern China
Avian haemosporidian parasites are widespread vector-borne pathogens that can influence host fitness, survival, and population dynamics. However, infection patterns and parasite lineage diversity remain poorly documented in many Asian bird populations, particularly within single host species…

High individual consistency in migratory strategies of American Herring Gulls (Larus smithsonianus) across multiple years
Migration is a fundamental component of the annual cycle of many bird species, largely driven by the need to access resources with seasonal availability. Birds employ diverse migratory strategies, undertaking short to long-distance migrations, presumably balancing energetic costs and risks with…

Identifying biases in avian leucocyte profiles arising from blood sampling regime: The effects of capture stress and repeated sampling
Physiological biomarkers offer valuable insights into the relationships between physiological responses and ecological conditions, serving as powerful tools to assess the health and resilience of wild populations. Among them, leucocyte profiles are particularly informative indicators of individual…

Mimetic birdsong affects automated bioacoustic species classification: A case study using the Northern Mockingbird, a ubiquitous North American mimic
While automated bioacoustic species classifiers play a growing role in avian population monitoring, they can produce false positive misclassifications by conflating acoustically similar sounds, including mimetic birdsong. We quantify the impact of the mimetic song of Northern Mockingbirds (Mimus…

Grassland birds in Asia: A review of their ecology, threats, and conservation
Asian grasslands, including the vast Palearctic steppes and alpine meadows of the Qinghai-Tibetan Plateau (QTP), form a vital part of the global temperate grassland biome. These open landscapes support unique bird communities, with many species specially adapted to harsh conditions. However…

Inherited biases reveal call-type-specific conspecific alarm responses in tits
Eavesdropping on heterospecific alarm signals provides critical predator information, yet whether recognition is driven by innate phylogenetic biases or learning and ecology remains unclear. We hypothesize that decoding strategies arise from interactions between evolutionarily inherited perceptual…

Toxicological impacts of persistent organic pollutants on avian physiology: A scientometric and systematic analysis
Persistent organic pollutants (POPs), primarily from industrial and agricultural sources, pose significant risks to birds due to their environmental pervasiveness, bioaccumulation, and toxicological impacts. Bird's trophic position and ecological traits make them vulnerable to POP exposure while…

Mechanisms of egg recognition in two cuckoo bunting hosts
Recognition and rejection of parasitic eggs are crucial host defenses against brood parasitism. Template-based recognition and recognition by discordancy are two main mechanisms of egg recognition used by bird hosts. However, even in hosts that utilize template-based recognition, a decrease or…

Migratory birds as global vectors and evolutionary incubators of antibiotic resistance genes
The global antimicrobial resistance (AMR) crisis, fueled by the cross-border dissemination of antibiotic resistance genes (ARGs), poses a critical and escalating threat to public health. Migratory birds, with their extensive mobility and broad ecological connectivity, effectively bridge…

Migration of Brown-headed Gulls on the Qinghai-Tibet Plateau: Potential transmission routes for highly pathogenic H5Nx virus
The Qinghai-Tibet Plateau serves as a critical hub along the Central Asian Flyway (CAF) and a recognized hotspot for the emergence of highly pathogenic avian influenza (HPAI) viruses. Despite recurrent outbreaks, the migratory dynamics of key reservoir species, such as the Brown-headed Gull…

Indirect fitness benefits of cognitive investment: Head size predicts adaptive nest-site selection in Barn Swallows (Hirundo rustica)
Cognitive traits such as brain size are hypothesized to influence avian reproductive strategies, yet the ecological mechanisms linking neural investment to fitness under natural conditions remain underexplored. According to the cognitive buffer hypothesis, larger brains should facilitate adaptive…

Climate driven rapid northward expansion of a songbird from subtropical to warm temperate zones: Dispersal corridors and future suitable habitat
While it is well established that climate change is driving species toward higher latitudes, the spatiotemporal dynamics of dispersal—particularly from subtropical to warm-temperate zones—remain poorly understood. Here, we combined ecological niche differentiation, functional landscape…

Penguins at the freshwater–marine boundary: Overlooked ecological linkages and climate-change risks
Penguins are usually framed as marine predators, yet freshwater can strongly alter the environments in which they forage, breed and survive. This narrative mini review synthesises evidence for how river outflows, glacial meltwater, snowmelt and rainfall shape penguin ecology across estuarine…

Behavioral innovation correlates with broader climatic niche breadths in birds
Behavioral innovation, defined as the ability to exhibit novel behaviors that may contribute to problem-solving and adaptability, has been increasingly recognized as a key factor in species’ resilience to environmental shifts. Here we investigate the association between behavioral innovation and…

Why are some White Eared Pheasants (Crossoptilon crossoptilon) grey? Investigating plumage divergence through habitat modeling
Plumage coloration plays a crucial role in ecology, often reflecting adaptive responses to environmental heterogeneity. According to Gloger's rule, animals in warm and humid regions are expected to exhibit darker coloration; however, the White Eared Pheasant (Crossoptilon crossoptilon), a…

Nanostructural determinants of angle-dependent iridescent coloration in two peafowl species
Structural colors arise from light interacting with nanoscale architectures, yet the relationships between multiple nanostructural features and their optical properties remain poorly understood. Peafowl feathers, iconic exemplars of iridescent coloration, feature photonic-crystal architectures that…

Evolutionary and ecological processes drive the global diversity of the avian family Paridae
Understanding how biodiversity is formed and maintained, is a key topic in both ecology and conservation biology. Both ecological and evolutionary processes jointly shape community assembly and maintain biodiversity, often through complex interactions. This study aims to examine how ecological and…
