Purpose: The aim of the study was to analyze the role of climate change in altering bird migration patterns in Vietnam. Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries. Findings: Climate change has significantly altered bird migration patterns in Vietnam, primarily due to shifting temperatures, altered precipitation patterns, and habitat loss. Warmer temperatures have caused many migratory birds to adjust their timing, either arriving earlier or delaying their departure, which often leads to mismatches with food availability and breeding conditions. Additionally, changes in rainfall patterns have impacted the availability of critical stopover sites, such as wetlands, which are essential for resting and refueling during migration. Habitat loss due to climate change and human activities has further compounded these challenges, threatening the survival of various bird species that rely on consistent migratory routes. Unique Contribution to Theory, Practice and Policy: Ecological niche theory, phenological mismatch theory & climate envelope theory may be used to anchor future studies on role of climate change in altering bird migration patterns in Vietnam. Conservation practices should focus on adaptive habitat management that accounts for the changing migration patterns of birds due to climate change. Policymakers should prioritize the development of climate-responsive conservation policies that explicitly address the impacts of climate change on migratory bird species.
