Or that the red-browed finches share nesting and parenting responsibilities.
Citizen scientists have contributed more than half of all species records to Australia's national biodiversity database, according to the CSIRO.
More than 62 million out of 125 million animal records have been provided by citizen research.
The chief scientist of the Australian Living Atlas (ALA), Erin Roger, said scientific data from members of the public can fill knowledge gaps about many under-represented species.
"Citizen science is a global movement," Dr Roger said.
"(It can) help to solve some of the biggest ecological questions and ultimately deliver better species outcomes."
Australians are best at recording bird data, which currently accounts for almost 50 per cent of all citizen scientist records, followed by plant species at 31 per cent.
Fungi are one of the lowest-represented taxonomic groups at just 1.4 per cent of records.
ALA director Andre Zerger said the over-representation of birds in general data was no surprise.
"Currently citizen science practices tend to favour large, brightly coloured, charismatic species," Dr Zerger said.
"There's so much untapped potential for scientific output from open-source data infrastructures like the ALA and around the world."
ALA records feed into the Global Biodiversity Information Facility, an international network of biodiversity data accessible to the general public.
