Birds such as this from Central and East Asia, M. m. lineatus are sometimes split under the name Black-eared
Kite, but such split is not well supported by genetics which appears to show it embedded within the migrans
group. These Black-eared types are paler, with a more contrasting dark cheek patch, bluish cere, shallow tail fork,
and conspicuous white underwing patches This species may be divided into three polytypic groups:
- Black [migrans Group] - Partly migratory; Palearctic to India
- Black-eared [lineatus/formosanus] - Highly migratory; East Asia
- Yellow-billed [aegyptius/parasitus] - Partly migratory; Africa
