Imagine this: a bird, thought to be gone for ages, suddenly reappears, bringing a spark of hope to a fragile ecosystem. This is exactly what happened in northern Tasmania, where the endangered eastern ground parrot has been rediscovered after disappearing for decades! It all started with a keen eye and a bit of luck. A firefighter, Robin Meyers, stumbled upon a peculiar feather during routine fieldwork at Narawntapu National Park.
The feather's distinct yellow banding immediately caught his attention. As Acting Fire Operations Officer Aidan Munro pointed out, "The yellow banding is a telltale sign of the eastern ground parrot's long tail feathers." This was a significant clue, as these elusive birds hadn't been seen in the northern coastal heathlands of Tasmania for a very long time.
These ground-dwelling parrots, with their mottled green plumage and long tails, are notoriously difficult to spot. They typically reside in the remote buttongrass moorlands of Tasmania's south and southwest. On the mainland, they face significant threats, with populations scattered and confined to small pockets of coastal heathland. They are listed as vulnerable in Queensland and New South Wales, and endangered in Victoria and South Australia, making Tasmania's southwest their primary stronghold.
The discovery of the feather sparked further investigation, especially as fire crews were planning a prescribed burn in the area. Sound recording devices were strategically placed across the coastal heath to listen for the parrots. After a two-month wait, the team's efforts paid off. "Three individual calls were recorded, seemingly of birds in flight around 6 pm, probably traveling from roost to a foraging area," explained Jarrah Dale, an environment wildlife biologist with NRE Tasmania.
The team utilized specialist software to analyze hours of acoustic data, filtering for the known call patterns of ground parrots, which had been established through earlier research at Melaleuca in the southwest. But here's where it gets controversial: the northern birds' calls differed slightly from their southwestern counterparts. This could indicate a dialect evolution within the species.
Further studies are being planned to gather more information about this population's habits. This exciting rediscovery not only expands the known range of eastern ground parrots in Tasmania but also highlights the importance of collaboration between fire management and conservation science teams.
And this is the part most people miss: Parks and Wildlife staff are now actively seeking public involvement. With summer and the tourist season approaching, visitors are encouraged to report any parrot sightings to the Natural Values Atlas. Narawntapu National Park is already home to five known parrot species, and citizen science contributions will help create a more comprehensive understanding of how ground parrots and other species utilize the park. Additional sound recording devices are being installed to continue monitoring the population and guide future management decisions.
