Erithacus rubecula
The red-capped robin was later moved to the genus "Petroica". The generic name is derived from the Ancient Greek words "petros" 'rock' and "oikos" 'home', from the bird's habit of sitting on rocks. Within the genus, it is one of five red- or pink-breasted species colloquially known as "red robins", as distinct from the "yellow robins" of the genus "Eopsaltria". It is not closely related to the American robin or the European robin; however, it is named after the European robin. Molecular research (and current consensus) places the red-capped robin and its relatives—the Australian robin family Petroicidae—as a very early offshoot of the Passerida, or "advanced" songbirds, within the songbird lineage.
