Patterns of bird migration phenology in South Africa suggest northern hemisphere climate as the most consistent driver of change
Abstract Current knowledge of phenological shifts in Palearctic bird migration is largely based on data collected on migrants at their breeding grounds; little is known about the phenology of these birds at their nonbreeding grounds, and even less about that of intra‐African migrants. Because climat...
