The
bell miner (
Manorina melanophrys), commonly known as the
bellbird, is a colonial
honeyeater endemic to southeastern
Australia. The common name refers to their bell-like call. "Miner" is an old alternative spelling of the word "
myna" and is shared with other members of the genus
Manorina.
[3] The birds feed almost exclusively on the dome-like coverings, referred to as "bell lerps", of certain
psyllid bugs that feed on
eucalyptus sap from the leaves. The psyllids make these bell-lerps from their own honeydew secretions in order to protect themselves from predators and the environment.
