Taxonomy
Yellow Rosella and Adelaide Rosella formerly considered to be separate species but now usually included in this species. Molecular studies have found P. e. nigrescens to be more distant than any of the others.
Subspecies
Seven subspecies are recognised by Clements[1]:
- P. e. nigrescens:
- Eastern Australia (coastal north-eastern Queensland)
- P. e. filewoodi:
- East central Queensland
- P. e. elegans:
- Eastern Australia (south-eastern Queensland to south-eastern South Australia)
- P. e. melanopterus:
- Kangaroo Island
- Kangaroo Island
Yellow Rosella
- P. e. flaveolus:
- Interior se Australia (Murray-Murrumbidgee river systems)
- Interior se Australia (Murray-Murrumbidgee river systems)
Adelaide Rosella
- P. e. subadelaidae:
- Southern South Australia (s Flinders Range)
- P. e. adelaidae:
- Southern South Australia (Mt. Lofty Range to Fleurieu Peninsula)
Habitat
Coastal and mountain euclypt and wet forest.
Behaviour
Diet
They eat the seeds of various trees, including native pines, blue fig, acacia and eucalyptus. Also grasses and shrubs, as well as insects and some tree blossoms. They also are readily attracted to bird seed trays.
Breeding
Using a tree hollow, the nest is lined with wood shavings and dust . The clutch contains 4-8 white eggs which are incubated by the female for about 20 days; both sexes care for the young. The young fledge after about 35 days, but depend on their parents for a further 35 days.
Vocalisation
Very vocal (often while feeding), with range of calls, the commonest being a two-syllable cussik-cussik. They also have a range of harsh screeches and metallic whistles.
Movements
Nomadic movements reported in winter at edges of range, but generally sedentary.
