How the Eagle and the Finch revealed a Night Parrot...

September 2017: Australian Wildlife Conservancy (AWC) ecologists have made a ground-breaking discovery, using exceptional natural history skills to uncover a Night Parrot population at Kalamurina Wildlife Sanctuary on the north shore of Kata Thandi-Lake Eyre.

It is the first record of the Night Parrot in South Australia for more than a century.

Night Parrot habitat.

AWC ecologists, John Young and Keith Bellchambers, found a Night Parrot feather in a Zebra Finch nest located next to a large patch of samphire north of Kati-Thanda-Lake Eyre. The feather has been independently confirmed as belonging to a Night Parrot by Ron Johnstone, the curator of Ornithology at the Western Australian Museum.

The discovery was made after AWC ecologists followed a series of clues using rare bush skills. The first clue was a cryptic shape captured on camera trap in 2016 in a remote location accessible only by helicopter.

Noting that Night Parrots had been recorded in 1883 in similar samphire habitat near Lake Eyre, John Young and Keith Bellchambers identified the shape on the camera trap as possibly a Night Parrot. They set about planning a dedicated search into one of Australia’s most remote regions.

  1. In July 2017, John, Keith and Kalamurina Manager Mark McLaren flew over 600 kms of transects across Kalamurina to locate potential Night Parrot habitat, applying knowledge gained by John Young in Queensland and evidence from the 1883 records.
  2. From the helicopter, John Young identified one prospective area which had a Wedge-tailed Eagle’s nest adjacent to prospective samphire habitat.
  3. The team honed in on the eagle’s nest, knowing that: (a) Zebra Finches like to nest under an eagles nest; and (b) Zebra Finches line their nests with feathers.
  4. Could the Zebra Finches at this location have collected a Night Parrot feather? After examining many finch nests, John Young found a small Night Parrot feather lining a recently built nest.

John Young described the extraordinary discovery as follows:

“Zebra Finches just love to build their nests in the base of a Wedge-tailed Eagle’s nest, so we walked over to investigate. Keith and I looked at many Zebra Finches’ nests before finally an unmistakable small green feather appeared within the fresh base lining of one of the nests.
People show excitement in many different ways, mine was to shake uncontrollably with numbing excitement and Keith’s was sheer disbelief with his hands holding his head. An incredibly emotional time for both of us.

In my eyes there was no doubt that this was the feather of a Night Parrot and the fact that the Zebra Finches nest was fresh, it seemed feasible that it was collected within a few hundred metres in the past few weeks.”

The discovery dramatically reshapes our understanding of Night Parrot ecology:

  • The Night Parrot populations in Queensland, also discovered by John Young, and the population in Western Australia are resident in spinifex. However, the Kalamurina population is located in an area of samphire, with no available spinifex habitat.
  • After no confirmed records of live birds for more than a century, it is now clear the Night Parrot exists in several locations spread across the continent including at least three states (Queensland, Western Australia and South Australia).

AWC’s management of Kalamurina has been important in securing and improving the integrity of Night Parrot habitats, including samphire. Kalamurina is the only property on the Warburton River (the major tributary of Kati Thanda - Lake Eyre) which is destocked and, in effect, feral herbivore free. It also has a healthy population of dingoes, which may reduce the threat posed by feral cats.

Kalamurina contains the only destocked portion of the Warburton Creek, the major tributary of Kati Thanda-Lake Eyre.

The next step in protecting the Lake Eyre Night Parrots is to map their distribution and assess the population size.  This will require deployment of song meters and camera traps in one of Australia’s most remote locations at a cost of around $75,000.
