Additionally, the poisoning of plateau pikas, perceived as pests, has disrupted the ecosystem, reducing biodiversity and affecting bird species that rely on pika burrows for nesting (Lai and Smith, 2003). 8.3 Recommendations for future research and conservation strategies To enhance conservation efforts and mitigate the threats facing endemic bird populations, future research and conservation strategies should focus on several key areas. Integrated conservation planning is essential, developing plans that consider both biodiversity and ecosystem services to balance conservation goals with human needs (Wang et al., 2021). Additionally, incorporating climate change projections into conservation planning will ensure that protected areas remain effective under future climate scenarios (Lu et al., 2022). Implementing habitat restoration projects that maintain the structural heterogeneity of landscapes will support a diverse range of species and ecological functions (Li et al., 2022). Finally, enhancing long-term monitoring programs and research to track changes in bird populations and habitats will inform adaptive management strategies (Jiang et al., 2023). By addressing these areas, conservation efforts can be more effective in protecting the unique avian biodiversity of the Qinghai-Tibet Plateau. 9 Future Directions and Research Needs 9.1 Areas for future phylogenetic and genetic studies Future research should focus on expanding phylogenetic and genetic studies to encompass a broader range of endemic bird species in the Qinghai-Tibet Plateau. Utilizing advanced genomic technologies, such as whole-genome sequencing and transcriptomics, can provide deeper insights into the genetic adaptations and evolutionary histories of these birds. Such studies should also explore the role of hybridization and gene flow in speciation processes, particularly in response to historical climatic changes and geographical barriers (Li et al., 2014; Wu et al., 2022). 9.2 Importance of integrating ecological and behavioral data Integrating ecological and behavioral data into phylogenetic and genetic studies is crucial for understanding how environmental factors influence the evolution of endemic birds. This includes examining habitat preferences, dietary habits, and reproductive behaviors. Research utilizing technologies such as GPS tracking, remote sensing, and UAV (Unmanned Aerial Vehicle) imagery can offer detailed insights into habitat use and migration patterns. Such integrative approaches will help elucidate the ecological niches and adaptive strategies of these birds, informing conservation efforts and ecological management (Li et al., 2022). 9.3 Need for longitudinal studies on climate change impacts Longitudinal studies are needed to monitor the impacts of climate change on the distribution, population dynamics, and genetic diversity of endemic bird species over time. These studies should focus on how shifting climatic conditions affect habitat availability, migration routes, and interspecific interactions. Understanding these dynamics is essential for predicting future changes and developing adaptive conservation strategies. Collaborative efforts that combine field observations, climate modeling, and genetic analyses will be key to addressing these complex issues (Lei et al., 2014; Jiang et al., 2023). By addressing these future research needs, we can gain a more comprehensive understanding of the origin, evolution, and conservation of endemic birds in the Qinghai-Tibet Plateau, ensuring their preservation in the face of environmental changes. 10 Concluding Remarks The systematic review of the origin and evolution of endemic birds in the Qinghai-Tibet Plateau reveals the intricate interplay between geological, climatic, and ecological factors that have shaped these species. The uplift of the Qinghai-Tibet Plateau and Quaternary climate changes have been crucial in creating diverse habitats, promoting speciation, and driving genetic differentiation among bird populations. Endemic birds exhibit significant physiological, morphological, and behavioral adaptations to cope with the high-altitude environment of
