Each winter, thousands of seabirds, seaducks, and waterfowl migrate from all directions to converge in the relatively calm and food-rich waters of Puget Sound. In summer, colonies of seabirds are busy attending their young. In spring and fall, the shorelines are full of shorebirds that stop to feed and rest during migration.
But Puget Sound is undergoing significant changes that impact birds. Some marine birds have suffered significant declines in Puget Sound, yet restoration projects are underway to improve ecosystem function. Professional scientists, citizen scientists, students are monitoring these changes and producing results.

Natural history and other resources
A new video series follows local scientists into the water, capturing the adventure behind the research. "Salish Sea Wild" is entering its second season and we interviewed the series host and producers. Among our burning questions: What's it like to have a Steller sea lion chew on your head?
An unintended consequence of the recovery of bald eagles (Haliaeetus leucocephalus) has been the impact on seabirds. The authors of a 2019 paper published in Ecology and Evolution suggest that the effects of bald eagle activity on a large glaucous-winged gull (Larus glaucescens) colony on Protection Island in the Strait of Juan de Fuca include the possibility of coexistence but also the possibility of gull colony extinction.
More than 70 percent of the seabird population of Puget Sound nests on a single island in the Strait of Juan de Fuca. That includes a massive colony of rhinoceros auklets that has drawn the interest of scientists and birders alike. Our writer Eric Wagner visited the island this summer and reports on a long-term study of the auklets that is revealing new information about the health of seabirds in the Salish Sea.

A 2017 paper in the journal Northwestern Naturalist looks at distribution patterns for Glaucous-winged Gulls across associated habitats in the Salish Sea.
A 2017 report from the Puget Sound Ecosystem Monitoring Program presents an overview of selected recent monitoring and research activities focused on toxic contaminants in the Salish Sea.
The Puget Sound Ecosystem Monitoring Program (PSEMP) is an independent program established by state and federal statute to monitor environmental conditions in Puget Sound.
The Puget Sound Ecosystem Monitoring Program released its fifth annual Marine Waters Overview this week. The report provides an assessment of marine conditions for the year 2015 and includes updates on water quality as well as status reports for select plankton, seabirds, fish and marine mammals.

Birds serve as useful indicators of ecosystem change and ecosystem health, biodiversity, condition of habitats, and climate change. Many people and organizations have their eyes on marine birds in Puget Sound.
The growing number of species of concern in the Salish Sea suggests ecosystem decay is outpacing recovery
The number of species of concern in the Salish Sea is growing at an average annual rate of 2.6%, according to a report published in the proceedings of the 2016 Salish Sea Ecosystem Conference in Vancouver, B.C.
