Saltmarsh Sparrows Threatened with Extinction as Coastal Marshes Drown
17 Oct
Summary
- Saltmarsh sparrows face high risk of extinction by mid-century due to rising sea levels
- Conservationists build makeshift rafts to protect sparrow nests from drowning
- Saltmarsh sparrows are an integral part of the coastal marsh ecosystem

As of October 17, 2025, the high-pitched chirps of the native saltmarsh sparrow are becoming increasingly rare in coastal marshes from Virginia to Maine. This small, freckled bird plays a crucial role in the delicate coastal ecosystem, but its survival is now under threat due to the devastating effects of rising global temperatures.
The Providence Journal reports that as sea levels continue to rise, the saltmarsh sparrow faces the risk of drowning in its exclusive breeding grounds within the coastal salt marshes. Naturalist Deirdre Robinson and her team of interns, including Cooper White and Jim O'Neill, are working tirelessly at the Jacob's Point Preserve to protect the endangered species.
According to conservation biologist Chris Elphick, the health of the saltmarsh sparrow population serves as an indicator for the overall well-being of the entire marsh system. As the birds struggle to survive, the entire coastal ecosystem is in danger of degradation and depletion.
To combat the drowning of saltmarsh sparrow nests and eggs, the dedicated team of researchers has devised a innovative solution - makeshift floating rafts to prop up the birds' nests during high tide. While these homemade devices do not address the root cause of rising sea levels, they are providing a crucial lifeline for the sparrow populations in the Jacob's Point Preserve. As the race to save the saltmarsh sparrow continues, the fate of this small bird and its coastal habitat hangs in the balance.
