Image does not show black heron (Egretta ardesiaca). The dark bird is a dark morph dimorphic heron (Egretta (garzetta/schistacea) dimorpha). The two white birds are white morph dimorphic herons and/or nominate little egrets (Egretta garzetta garzetta): taxonomy, status and field characters of East African egrets are (as of 2010) still not fully resolved.
