Which regions do northern populations of the Oriental Dwarf Kingfisher partially migrate toward during the non-breeding season?
Answer
The Malay Peninsula and Sumatra
The migratory behavior of the Oriental Dwarf Kingfisher is complex, showing that while many populations remain sedentary residents throughout the year, others exhibit partial migration based on regional climate patterns. Specifically, the northern populations, which include birds found in Myanmar and Bangladesh, undertake seasonal movements when the primary breeding season concludes. These northern groups shift their location southward, settling temporarily in the Malay Peninsula and the island of Sumatra during the non-breeding period, thus utilizing resources across a significant longitudinal span until conditions favor their return north.
