Help Us Count Shorebirds!

Thank you to all of our 2016 Puget Sound Shorebird Count volunteers for getting up before dawn to sit in subzero temperatures, peer through binoculars, and carefully count all the shorebirds in your assigned area. It is your passion for conservation that allows us to collect this important data every year. By studying winter population numbers, we can isolate species and habitats of greatest conservation need.



In the winter of 2012, Ecostudies Institute, in collaboration with Washington Dept. of Fish and Wildlife and US Forest Service International Program, began coordinating a Citizen Science winter shorebird monitoring effort in Puget Sound. The goal of this effort is to provide a mechanism to monitor long-term changes in shorebird populations in Puget Sound, while at the same time contribute to a large-scale, flyway-wide shorebird monitoring effort called the Pacific Flyway Shorebird Survey, which is coordinated by Point Blue Conservation Science

Shorebirds using the Pacific Flyway are dependent upon a network of widely spaced estuarine sites between the Arctic and South America for wintering and migrating to and from their breeding grounds. Shorebirds also have exhibited long-term population declines. The lack of broad-scale coordinated monitoring along the Pacific Flyway limits our ability to understand the problem and design conservation strategies to benefit shorebirds

In Washington State, Puget Sound contains 26 estuarine sites that support > 1,000 shorebirds. However, the major stopover and wintering areas, are located in four large estuaries in northern Puget Sound.

Key Results

  • In 2015  volunteers surveyed 21 sites and counted 33,519 shorebirds and 413 raptors. Once again, Dunlin led the count, with Bald Eagles and Northern Harriers leading the raptors.
  • The number of volunteers continued to grow in 2014, when 30 individuals participated in the count.  Twenty-two sites were surveyed and 20,189 shorebirds and 58 raptors were counted.  As in previous counts, the most abundant shorebird was Dunlin.
  • In 2013, we increased the number of sites monitored to 21 and the number of count participants increased too.  Twenty-one volunteers counted 13,581 shorebirds and 57 raptors.  The most abundant raptors on the counts were Bald Eagles and Northern Harriers.
  • In 2012, 15 volunteers monitored 15 sites and counted 15,485 shorebirds. Not surprisingly, the most abundant shorebird was Dunlin. Total raptors counted included 31 individuals of 6 species.

Overall, we have built a solid foundation of shorebird monitoring in Puget Sound that we plan to continue in the future.  With the amount of estuary restoration taking place in Puget Sound, these data will be extremely valuable in describing some of the long term effects of those conservation actions.  Read more about our work on the Effect of Estuary Restoration on Birds.
