The latest update to the International Union for Conservation of Nature’s (IUCN) Red List of Threatened Species reveals a disturbing trend in shorebird populations, with 16 migratory species in the Americas reclassified to higher threat levels. According to Manomet Conservation Sciences, immediate action is essential to counter these alarming declines, which have seen certain populations fall by over a third in recent decades.
The IUCN Red List, established in 1964, is the most comprehensive global resource for assessing species’ extinction risks. Contributing to the recent findings, a 2023 study published in Ornithological Applications examined shorebird migration data from 1980 to 2019. Led by Stephen Brown, PhD, Vice President of Science at Manomet, the study found that more than half of North American shorebird species have experienced population declines of 50% or more, with these decreases worsening in recent generations.
Manomet emphasizes that coordinated conservation efforts are now more critical than ever. "The decline in shorebird populations reflects a broader instability in ecosystems, with far-reaching implications for the health of coastal environments and communities," says Rob Clay, PhD, Vice President of Flyways at Manomet. Clay notes that effective collaboration among governments, scientists, and local communities is key to tackling habitat loss, climate change, and other stressors that threaten both the birds and the ecosystems they inhabit.
Among the species affected:
Despite these concerning trends, there are positive examples of successful conservation efforts. Manomet’s collaboration in the Oystercatcher Recovery Working Group has led to a 45% increase in the American Oystercatcher population, exceeding the original goal of a 30% rebound. The Piping Plover has also shown promising trends in recovery, demonstrating the effectiveness of targeted conservation initiatives.
“Shorebirds are especially vulnerable to threats like habitat degradation and climate change because they rely on specific migratory routes and stopover sites for feeding and rest,” explains Juliana Bosi de Almeida, PhD, Managing Director of Flyways at Manomet. "Protecting these birds is not only crucial for wildlife conservation but also for maintaining the health of coastal ecosystems that offer essential services such as storm protection and food resources."
Manomet calls for increased funding and collaborative efforts to address the critical threats faced by migratory shorebirds. "The need for coordinated global conservation action is urgent," says Elizabeth Schueler, President of Manomet Conservation Sciences. "The drastic declines in shorebird populations indicate broader environmental challenges that require immediate and unified efforts."
Manomet continues to advance science-driven solutions to conserve shorebird habitats, working with international partners to reverse current population trends. The organization remains committed to protecting these essential species and the ecosystems they represent, ensuring the long-term health and stability of coastal environments worldwide.
