The study, published in the journal "Biological Conservation," focused on the endangered Gouldian Finch, which is found only in the savannas of northern Australia.
The researchers used satellite data to map fire scars in the finches' habitat over a 20-year period, and then used statistical models to assess the relationship between fire frequency and the abundance of finches.
They found that the abundance of Gouldian Finches was significantly lower in areas that had experienced more frequent fires.
"Our findings suggest that frequent fires along waterways are a major threat to the survival of the Gouldian Finch," said lead researcher Dr. Sarah Legge, from the Australian National University.
"Fires can destroy the finches' nests and food sources, and they can also make the birds more vulnerable to predation.
"We urgently need to develop and implement fire management strategies to protect waterways in the savanna from frequent fires, and to ensure the survival of the Gouldian Finch."
The Gouldian Finch is one of Australia's most iconic birds, and it is a popular tourist attraction.
The species is listed as "vulnerable" by the International Union for Conservation of Nature (IUCN).
