What causes the Pheasant-tailed Jacana to exhibit different residency patterns compared to the Northern Jacana in Florida?

Answer

The Asian species migrates seasonally to follow the availability of suitable water bodies, unlike the fixed residency in Florida's stable climate.

The Northern Jacana in Florida is largely non-migratory due to stable conditions, whereas the Pheasant-tailed Jacana in Asia exhibits clear migratory patterns to follow seasonal availability of water bodies dictated by factors like monsoons.
