Fish & Wildlife officials survey the bird count at the Grays Harbor Refuge.
Grays Harbor Shorebird and Nature Festival
2026 Bird Surveys
Shorebird surveys at Grays Harbor National Wildlife Refuge are conducted every few days during spring migration, mid-April through mid-May. The Refuge Biologist and Volunteers are positioned along the Sandpiper Trail for up to three hours before the predicted high tide and may not be able to answer questions while they are counting shorebirds.
GH Shorebird Survey Report – April 16, 2026
Time: 10:27 AM – 2:57 PM • High Tide: 9.7 ft @ 1:27 PM (Aberdeen)
Surveyors: JB, CC
A total of 4,964 shorebirds were observed. Dunlin (1,750) and Western Sandpiper (780) were most numerous, with a large group of ~2,300 shorebirds (unknown) roosting on Mini Moon Island.
With tides reaching above ~9.0 ft, most mudflat habitat was inundated, and birds were either pushed into roosting areas or moved off-site. Activity was centered around roost locations rather than feeding areas.
Species Counts:
• Black-bellied Plover: 94
• Semipalmated Plover: 1
• Dunlin: 1,750
• Western Sandpiper: 780
• Least Sandpiper: 1
• Red Knot: 5
• Dowitcher spp.: 19
• Yellowlegs spp.: 6
• Whimbrel: 8
• Unknown Shorebirds (MMI): 2,300
GH Shorebird Survey Report – April 17, 2026
Time: 11:18 AM – 3:48 PM • High Tide: 9.8 ft @ 2:18 PM (Aberdeen)
Surveyors: RM (Training JCB, DL, EB, JL, CL)
A total of 12,283 shorebirds were recorded, driven by a large concentration of Dunlin (10,800). Western Sandpiper (1,200) and Whimbrel (34) were also present in good numbers.
Tides again exceeded ~9.0 ft, limiting available mudflat habitat and concentrating birds into dense roosts. Large flocks were observed moving together between roost sites, with occasional tight group formations as birds shifted positions.
Species Counts:
• Black-bellied Plover: 214
• Dunlin: 10,800
• Western Sandpiper: 1,200
• Red Knot: 3
• Dowitcher spp.: 9
• Yellowlegs spp.: 23
• Whimbrel: 34
GH Shorebird Survey Report – April 19, 2026
Time: 12:59 PM – 5:14 PM • High Tide: 9.4 ft @ 3:59 PM (Aberdeen)
Surveyor: JG
A total of 11,188 shorebirds were observed. Dunlin (8,700) remained dominant, with increasing numbers of Western Sandpiper (2,260).
The tide reached ~9.4 ft and ran slightly higher (0.3 ft) than predicted. As a result, birds were compressed into roosting areas, with large, cohesive flocks forming and shifting across the landscape.
Species Counts:
• Black-bellied Plover: 93
• Semipalmated Plover: 72
• Dunlin: 8,700
• Western Sandpiper: 2,260
• Least Sandpiper: 6
• Red Knot: 10
• Dowitcher spp.: 10
• Yellowlegs spp.: 11
• Whimbrel: 26
GH Shorebird Survey Report – April 21, 2026
Time: 3:48 PM – 6:48 PM • High Tide: 8.6 ft @ 5:48 PM (Aberdeen)
Surveyors: DL, JCB
A total of 50,295 shorebirds were recorded—the highest count of the survey period. Dunlin (34,600) and Western Sandpiper (15,500) dominated, with strong numbers of Dowitchers (124).
Although the predicted tide was lower, actual water levels reached ~9.2 ft (0.6 ft higher than predicted). Birds were widespread and everywhere across the mudflat
These conditions—combined with evening timing—created excellent viewing opportunities, with birds often packed tightly and moving in coordinated groups.
Species Counts:
• Black-bellied Plover: 42
• Semipalmated Plover: 23
• Dunlin: 34,600
• Western Sandpiper: 15,500
• Red Knot: 124

GH Shorebird Survey Report – April 24, 2026
Time: 5:45 AM – 9:00 AM • High Tide: 8.9 ft @ 7:14 AM (Aberdeen)
Surveyor: RJM
An estimated 17,531 shorebirds were observed. Western Sandpiper (9,000) and Dunlin (6,000) dominated, with strong numbers of Semipalmated Plover (500) and Red Knot (230).
The tide reached above 9.0 ft and was approximately 0.5 ft higher than prediction . Birds were highly concentrated and roosting close to the boardwalk, providing excellent viewing opportunities.
Survey conditions were initially challenging due to low light and elevated tides, but at sunrise, large flocks formed dense aggregations, with frequent movement and shifting groups as birds adjusted to changing light and water levels. Peak migration is in progress, with high diversity and abundance across species.
Species Counts:
• Black-bellied Plover: 157
• Semipalmated Plover: 500
• Dunlin: 6,000
• Western Sandpiper: 9,000
• Least Sandpiper: 30
• Red Knot: 230
• Dowitcher spp.: 84
• Yellowlegs spp.: 16
• Whimbrel: 14
• Unknown Shorebirds: 1,500
Other Notable observations: Bald Eagle (1) and Orange crowned warblers
