Shorebirds have been trickling through the Portland area all month. Finding proper habitat can be challenging. As wetlands dry up during the summer, we have to hope that deeper bodies of water recede enough to create mudflats for shorebirds to feed on. This Greater Yellowlegs was at Force Lake in north Portland.
Typically seen wading, Greater Yellowlegs will occasionally swim in groups to catch small fish.
This juvenile Western Sandpiper, showing the characteristic rusty suspenders, was taking advantage of low water levels at Smith and Bybee Wetlands.
The main lake at Fernhill Wetlands has receded enough to create some nice mudflats, here being enjoyed by a Pectoral Sandpiper.

Spotted Sandpipers nest in the Portland area. Juveniles, like this one, can be recognized by the barring on the wing coverts.
Semipalmated Plovers are surely one of the cutest shorebirds. The scaly pattern on the wings tells us that this is a juvenile.
Racetrack Lake, located on Sauvie Island, sort of in between the end of Rentenaar Road and the east shore of Sturgeon Lake, has been quite good for shorebirds recently. Good shorebird habitat has been very hard to find in the Willamette Valley this summer, with conditions either too dry or too wet, so this patch of mud has been quite attractive to southbound migrants. Unfortunately, birds were pretty distant so they didn’t present great photo opportunities.
Long-billed Dowitchers were one of the more common shorebirds on this visit.
There were a few Short-billed Dowitchers mixed in, although the distance made identification challenging. Note the whitish belly, the spotted sides of the breast, and the tiger-striped tertials.
Semipalmated Plovers rank near the top of the most adorable shorebird category.
American White Pelicans were considered pretty rare in the Portland area not that long ago. Now you can expect 100 or more around Sauvie Island in the late summer.
Great Egrets are also very common this time of year.
Water levels continue to drop at Racetrack Lake, so there should be some decent mud for a while longer. Happy Summer.
I made a quick trip to Fernhill Wetlands and Jackson Bottom to look for shorebirds. My first bird of the morning was this Killdeer standing on the sidewalk. I guess that counts.
There is a frustrating lack of mudflats in area wetlands this year. Areas are either dry with lots of vegetation or are full of water. I did manage to find this Wilson’s Snipe (front) feeding with a juvenile Short-billed Dowitcher.

Lots of American White Pelicans are in the Willamette Valley right now.
The wetland rehabilitation at Fernhill Wetlands has resulted in much less exposed mud, but the thick emergent vegetation is hog heaven to rails, like this Virginia Rail.
In the “invasive but adorable” category are this Nutria with her baby.
Brush Rabbits rule the “native AND adorable” category.
These two Black-tailed Deer were at Jackson Bottom. I found it interesting that the little spike buck in front still had his antlers completely encased in velvet while the fork buck in back has already shed his velvet to reveal polished antler.
There is still about a month of shorebird migration left. I hope we get some good mudflats to bring them in. Happy Summer.
I’ve recently made two trips to Grays Harbor in Washington, once to scout and the other to lead my shorebird class. This estuary is a major staging area for migrating shorebirds in spring.

Don’t neglect to look at all the little brown ducks! This is a King Eider, a rare visitor from Alaska. It is distinguished from Common Eider by the slender bill and the scalloped markings on the sides.
Bowerman Basin is an inlet on the north shore of the harbor. It is the last area to fill during high tides, so shorebirds often congregate here. This is a view from the boardwalk.
Peregrine Falcons are attracted by the large numbers of shorebirds in the harbor.
This is a view of the boardwalk on a Thursday morning.
This is the boardwalk on a Saturday afternoon. Unfortunately, birders outnumbered birds by about five to one on this afternoon.
Greater White-fronted Geese
Marsh Wrens are common along the marshy edges of Bowerman Basin.
The willow thickets and woods along the boardwalk attract migrants like this Golden-crowned Sparrow.
I took my shorebird class to Grays Harbor in Washington, one of the prominent staging areas for migrant shorebirds on the West Coast. The cold wet spring continues, so diversity was a little low, but there were lots of birds to see.
At Damon Point State Park, near the mouth of the bay, we found good numbers of Marbled Godwits and Short-billed Dowitchers.
At Bowerman Basin, part of Grays Harbor NWR, a long boardwalk extends along the edge of the mudflats. As the basin fills with the rising tide, the birds are pushed closer to shore for excellent views.
Here we can see a Black-bellied Plover, a couple of Semipalmated Plovers, two Caspian Terns, lots of Dunlin, and some Western Sandpipers.
Here is a closer look at the lovely Semipalmated Plovers mixed in with Western Sandpipers.
I didn’t notice the bird at the time, but when I downloaded this shot of Western Sandpipers I immediately noticed the Least Sandpiper among them. Least Sandpipers feed in a crouched position with their feet far forward. On closer inspection, you can see the tiny bill and the pale legs. (lower right corner, if you are still looking)
Here’s a closer look at the Least Sandpiper between two Westerns.
