Dunlin now VULNERABLE on Iceland's RED LIST. One of the waders most impacted by new forestry plantations: wadertales.wordpress.com/2022/06/18/i... Over 50% of Europe's Dunlin nest in Iceland so recent declines are of concern to whole East Atlantic Flyway. #ConservationScience🌍
Putting this in context: About 75% of Europe's Whimbrel breed in Iceland. Over 50% of Europe's Dunlin. About 50% of Europe's Golden Plover. About 20% of Europe's Redshank. SCARY! #ornithology

At the end of every new road/track in Iceland is a new summer cottage, a tourist development, a newly planted forest or energy infrastructure. All these developments impact breeding waders but the birds' problems start with the road. wadertales.wordpress.com/2025/12/02/r... #ConservationScience🌍

Effect of low‐traffic roads on abundance of ground‐nesting birds in sub‐Arctic habitats
Roads are among the most widespread anthropogenic structures, and their presence can impact biodiversity in surrounding landscapes through disturbance and collision risk, particularly when traffic vo...

The call of the Whimbrel
The seven-note whistle of the Whimbrel is a classic sound, welcomed by Icelanders at the end of a long, dark winter. These wonderful waders are responding badly to recent changes to Iceland’s lands…
