Fossil bones in Australia's caves show wetlands once hosted diverse shorebirds, including plains-wanderers and migratory species, during the last Ice Age.
Fossil shorebird remains in Australia’s Naracoorte Caves reveal that wetlands once supported diverse bird populations, including the plains-wanderer, sandpipers, and snipes, during the last Ice Age.
Over 300 bones, mostly from plains-wanderers, indicate these birds thrived in woodlands before a major drying phase around 17,000 years ago caused habitat loss and species decline.
Evidence of migratory birds from the Northern Hemisphere and New Zealand suggests long-distance travel.
The findings highlight how past climate change reshaped ecosystems and inform current conservation efforts for shorebirds facing similar threats today.
