Grebe hybrids are rare. Some crosses have been describes, such as Hooded Grebe (P. gallardoi) x Silver Grebe (P. occipitalis)(Storer, 1982) and Western Grebe (Aechmophorus occidentalis) x Clark’s Grebe (A. clarkia)(Konter, 2009) The numbers of the latter hybrid are increasing in at least two populations (Konter, 2011; Konter, 2012).

On Madagascar there appears to have been extensive hybridization between the endemic (and now extinct) Alaotra Grebe (Tachybaptus rufolavatus) and Little Grebe (T. ruficollis) (Voous & Payne, 1965).
