Subspecies

About nine subspecies recognised[1].

The last two subspecies have been proposed as a split called Tricolored Grebe, Tachybaptus tricolor.

  • One more subspecies, albescens has been proposed for the yellow/orange eyed Asian birds currently included by Clements in subspecies capensis (all other capensis have dark eyes). Under this classification capensis is restricted to Africa south of the Sahara and Madagascar while albescens is the race inhabiting the Caucasus east to Iran, Central and South Asia including Sri Lanka. IOC, H&M4 and Birdlife/HBW all adopt this classification and recognize albescens as valid.
