Overview
The Orange-bellied Parrot (Neophema chrysogaster) is a jewel-like, critically endangered Australian grass parrot and one of only three migratory parrot species in the world. Famous for its dazzling plumage featuring bright grass-green upperparts, a glowing golden-yellow chest, an electric-blue frontal browband, and a diagnostic, bright orange oval patch on its lower belly, this plucky little bird undertakes an arduous annual trans-marine migration across the stormy Bass Strait between remote southwestern Tasmania and mainland Australia.
Biology and Physical Characteristics
Neophema chrysogaster is a small, compact parrot with a rounded head and a graduated, pointed tail. Its upperparts are a luminous emerald to grass-green, contrasting with brilliant sapphire-blue wing margins and a distinctive two-toned blue frontal band running between the eyes. Its underparts are bright yellow, dominated on the lower belly by a prominent, circular orange-red patch that is larger and brighter in adult males. Its small, hooked grey bill is specialized for husking tiny, oil-rich seeds from chenopod saltmarsh herbs and sedges.
Behavior and Ecology
Orange-bellied Parrots are ground-foraging seed specialists that spend non-breeding winter months scouring coastal saltmarshes and samphire flats in Victoria and South Australia. In early spring (September), they undertake a perilous 500-kilometer southward flight across the Bass Strait to reach Melaleuca in Tasmania’s remote southwest wilderness. There, they nest exclusively in natural hollows of ancient eucalyptus trees (particularly Eucalyptus nitida). Females lay clutches of four to six eggs, while males feed their brooding mates by regurgitating seeds collected from buttongrass plains.
Conservation and Human Impact
Classified as Critically Endangered on the IUCN Red List, the Orange-bellied Parrot is one of the world’s most endangered birds, having plummeted to an all-time low of just 17 returning wild individuals in 2016. Major drivers of decline include widespread loss and fragmentation of coastal wintering saltmarshes to industrial ports and urban sprawl, nest competition from introduced starlings, and psittacine beak and feather disease (BFDV). A massive national recovery program involving captive breeding, nest-box provisioning, and the release of captive-reared juveniles has helped wild breeding numbers rebound past 70 birds.
Interesting Factoid
The Orange-bellied Parrot is one of only three migratory parrot species on the planet, flying hundreds of miles across the notoriously treacherous, storm-wracked waters of the Bass Strait every single year.
