Wetland Secretive Bird Monitoring - Volunteers Needed for the 2026 Survey Season
Surveyors Needed to Track Wetland Secretive Birds – Register TODAY!
​
Whether you are a seasoned veteran or just interested and new to the program, it is time to sign up for details and information on the 2026 Season of Wetland Secretive Bird Monitoring.
​
This effort has truly flown only because of the dedicated efforts of our volunteers. We can honestly say that the work you do is contributing to the conservation and protections of these elusive species along with the habitats they need to thrive.

Puget Sound Bird Observatory’s Regional Wetland Secretive Bird Monitoring project is a community science effort that uses volunteers to collect and record data according to a specific protocol for assessing regional populations and trends of marsh birds across the Puget Sound trough.
​
Puget Sound Bird Observatory began to review available distribution and abundance data on several wetland obligate species of birds in 2016 and identified a data gap between what was being recorded in species maps and antidotal observation, including eBird across the Puget Sound trough. A scoping project was launched in 2016, initially just in King and Snohomish Counties, to assess the presence of four (4) wetland obligate species (American Bittern (Botaurus lentiginosus), Sora (Porzana Carolina), Virginia Rail (Rallus limicola), and Green Heron (Butorides virescens) and two (2) wetland associated species for which there are population concerns, Marsh Wren (Cistothorus palustris) and Willow Flycatcher (Empidonax traillii). With the support of a large community of volunteer citizen scientists, this project has grown to roughly 140 habitat specific wetlands being surveyed across Skagit, Snohomish, King and Pierce Counties.
​
From the beginning the goal has been to collect statistically robust data that can be used by regional land managers and habitat managers in assessing ecosystem health. Project design allows for long-term regional monitoring that will provide landscape scale status and trends as well as site specific data of select wetland bird species throughout the Puget Sound trough. This project has also created access and engagement for volunteers with the opportunity to participate in field work and data collection across a large effort for monitoring birds.
​
Birds are a major taxon that provides information on overall biological condition. They have high public appeal (Furness and Greenwood 1993), and are relatively efficient to sample. Marsh bird abundance and distribution over space and time indicate habitat quality and can be used as measures of restoration success (Neckles et al. 2002; U. S. EPA 2002). However typical landscape scale monitoring efforts such as the Breeding Bird Survey or Christmas Bird Count do not fully capture many of these elusive wetland species. While the six species chosen for this monitoring are not priority species, the lack of accurate population data can allow these species to be forgotten when assessing habitat quality and ecosystem health. Dr. Elliot Coures said of the American Bittern while studying it in 1874, “He prefers solitude, and leads the eccentric life of a recluse, forgetting the world, and by the world forgot.” Puget Sound Bird Observatory sees a need here to make sure these birds are not forgotten across the face of habitat loss but also as new and innovative wetland projects are implemented across Puget Sound.
​
Most of our selected wetland sites are on public lands or lands with public/private partnerships where engagement helps build appreciation and understanding of these unique and special places.
​
Oversight and expertise for this project is provided generously by Dr. Courtney Conway of the University of Idaho's Cooperative Fish & Wildlife Research Unit, by Ruth Milner, Washington Dept. of Fish and Wildlife, and by the scientific expertise within PSBO’s leadership team.
Birds have broad public appeal because of their almost ubiquitous presence, variety across species and engaging behaviors. Understanding avian abundance and distribution in these wetlands gives key indicators of environmental health and habitat well-being. Documenting accurate data on these birds also supports preservation of unique and special places for human beings. Grounding marsh habitat management in sound science allows us to work toward healthy spaces for birds and the public across the region's wetlands.

Every survey adds a vital piece to the puzzle of wetland conservation. By lending your eyes and ears, you help ensure these secretive species are not overlooked—and that these elusive wetland species thrive across our landscapes.

BASIC INFORMTION
Back in 2016, inspired by conversations at a Pacific Birds Habitat Joint Venture meeting, PSBO launched a bold regional monitoring project to solve a puzzle: Why were some of our most iconic marsh birds—like the American Bittern, Sora, and Virginia Rail—so rarely recorded in traditional bird surveys? Were they truly scarce, or simply overlooked?
​
To find out, PSBO began surveying a handful of wetlands. Today, this effort has grown into one of the largest volunteer-driven monitoring programs in the Pacific Northwest, spanning 220+ wetlands across 11 counties. At the heart of this success is a dedicated community of volunteer field surveyors—people like you who bring curiosity, patience, and a love of nature to the marsh. Now, we are expanding into Southwest Washington and would love your help in joining our monitoring team.

-
Wetland routes span across Whatcom, Skagit, Snohomish, King, Pierce, Thurston, Mason, Kitsap, Island, Grays Harbor, and Pacific Counties.
-
Each surveyor or surveying team is loaned equipment for conducting these broadcast/distance sampling surveys. Due to the cost of this equipment, we do ask that every surveyor complete a minimum of four surveys. These can take place almost any time between March 27th and June 12th.
-
The amount of time spent surveying varies a great deal. It depends on whether you choose sites near your home or further away. In addition, each route is slightly different and ranges from very easy access to somewhat complex. In general, an ‘average’ survey will take approximately 2.5 hours.
-
A standard protocol is used to specifically detect American Bittern, Sora, Virginia Rail, Green Heron, and Pied-billed Grebe.
Why Your Role Matters
-
These elusive birds are indicators of wetland health.
-
Because they are so hard to detect, they often slip through the cracks of large-scale surveys like the Breeding Bird Survey or Christmas Bird Count.
-
PSBO’s habitat-specific approach is filling critical data gaps, and the growing dataset is already shaping management strategies for these species.

RETURNING SURVEYORS
We are delighted to have you back to survey again this year! To “sign-up” for the 2026 season, please send the following to my email at: Project Manager - Cindy Easterson
-
Name:
-
City where you live:
-
Phone:

Information about equipment distribution and refresher training will be sent to you directly once you let me know your desire to participate again this year. Of course, you are welcome to attend any of the training dates listed for new volunteers if you would like a refresher. Simply use the link in the NEW SURVEYORS information to register for a training event.
Please Remember the Minimum Commitment - Volunteers are asked to complete four surveys between late March and mid‑June. Each survey typically takes 1–4 hours, depending on the site. This level of participation helps ensure that PSBO can confidently loan out the specialized equipment needed for the project and maintain high‑quality, consistent data.
​
