Egretta garzetta - this taxon is not recognised by BirdLife International. Egretta garzetta and E. dimorpha (Sibley and Monroe 1990, 1993) have been lumped into E. garzetta following Kushlan and Hancock (2005) who also lump E. gularis with E. garzetta; this latter treatment is under review by the BirdLife Taxonomic Working Group.
