Podicipedini is a tribe of waterbirds belonging to the family Podicipedidae containing the genera Aechmophorus and Podiceps.
Members of this tribe of grebes are characterized based on the presence of nuptial plumes and downy young with a bare crown patch.
They are more specialized for diving though the anatomy that enables them to do so makes them weaker to stand upright.
[2] The inclusion of the Neogene genera of Pliolymbus and Thiornis is based on their possible reclassification as junior synonyms as Podiceps.
One morphological study from Fjeldså (2004) found Rollandia to be the basalmost extant genus of grebe, with Thiornis being classified as a stem-grebe.
