Caspian Tern – John Rakestraw

Fort Stevens State Park

I went to Fort Stevens to look for shorebirds this week. The main push of spring migrants hadn’t arrived yet, but numbers were definitely on the increase. I was pleased that I timed the tide correctly at Parking Lot D. This little bay fills quickly when the tide comes in, so it was nice to have extensive mudflats on this visit.

Nala and I spent a unseasonably warm morning around the towns of Cannon Beach and Seaside. Spring migration is just starting to kick in, but things are still pretty slow.

Since the tide was out, we were able to get pretty close to Haystack Rock and its compliment of Harlequin Ducks.

This band of California Gulls were hanging out on the beach (yellow legs), accompanied by a couple of young Western/Glaucous Winged (pink legs).

Most of the wintering Mew Gulls have left, but this one was on the beach in Gearhart.

Small numbers of Caspian Terns have returned to the Necanicum Esturary. A few were holding fish, trying to impress the ladies. It should work. I can be won over pretty easily with a vegan doughnut from VooDoo.

This bird was vexing. He is obviously a Ruby-crowned Kinglet, but I was convinced he was a Hutton’s Vireo. He moved very methodically, actually standing still for several seconds at a time. Spastic kinglets never sit still for that long.
But he has the classic field marks of a Ruby-crowned Kinglet; a black bar at the base of the secondaries (lacking in Hutton’s), and black legs with yellow feet (all gray in Hutton’s). I don’t know why his behavior was so un-kinglet-like. Just another reminder to mind the details as well as the gestalt.

North Coast

I made two trips to the coast this week, once to scout for my Portland Audubon shorebird class, and again for the class itself. It is amazing how much difference a couple of days can make in the make-up of bird life in a given area. On Thursday, I found a total of 11 shorebirds of two species. During the class we found hundreds of individuals of 10 species. I am so glad it was not the other way around. This is the view from the Necanicum River Estuary, looking south. The tiny bump in the middle is Haystack Rock, about 12 miles away.

Caspian Terns are common and very vocal all along the coast.

This Semipalmated Plover was the only shorebird at the tidal ponds at Fort Stevens.

Here is a good example of why this time of year may not be the best for learning gull ID. The plumage on this gull is bleached out and very worn. Judging from the size, shape, and pink legs on this bird (next to a normal non-breeding California Gull) I’m guessing this is a Glaucous-winged Gull, perhaps in his second cycle. I hope he grows some new feathers soon, or it will be a very cold autumn and winter.

Fort Stevens State Park

When the tides are right, the area around Parking Lot D at Fort Stevens State Park can be very productive.

On my recent visit, I found about 400 Caspian Terns in the bay. Many of the birds were presenting fish to their lady loves, and a few were rewarded accordingly (nudge, nudge, wink, wink). A Bald Eagle would occasionally take a pass at the flock, sending the terns off in a big swirling mass, but the birds would quickly settle down again.

One of my favorite birds of the day was this breeding plumaged Bonaparte’s Gull. I watched the bird fly in and settle on the mud flat. I snapped a couple of frames from a great distance, planning on getting better views. But, as is often the case, the bird took off before I could get any closer.

Over the past few years, this site has been become a productive spot for shorebirds. The spring shorebirds migration is well past its peak, but there were still a few birds around. This little flock was actively feeding along the shore, so I sat on my knees in the sand and waited for the birds to come to me. Shorebirds are very wary of people standing upright, but if you sit down, or better yet, lie down, the birds will come quite close.

This blurry Dunlin was the only member of her species in the flock.

Semipalmated Plovers made up the bulk of this flock.
While the spring shorebird movement is about done, the southbound migration begins in about six weeks, so we don’t have too long to wait for another shorebird fix.

North Coast

October 4, 2013 by John Rakestraw, posted in nesting, OR Birding Sites, seasonal movements

I spent a warm sunny morning around Cannon Beach and Seaside. The first stop was Silver Point, just south of Cannon Beach, for a sea watch. There were plenty of birds out there, way out there. It is what I call birding at the edge of imagination. You have an idea of what you are seeing, but realistically, there is a lot of guessing involved. I did see the wing flash of Sooty Shearwaters and several flocks of White-winged and Surf Scoters, but most of what I saw were unidentifiable specks. Nala was waiting somewhat patiently in the car, so we soon went to Tolovana Wayside and walked to Haystack Rock.

The tide was coming in, so I couldn’t get too close to the rocks. Still, you could see several Harlequin Ducks. Here is a male and female, with a Black Oystercatcher on the right. I didn’t see the Oystercatcher when I was in the field, only when I developed the photo.

A log, which has obviously been in the water for a long time, had washed up on shore, and the American Crows were busy picking at the barnacles.

Nala, taking a break

The next stop was the Cove, at Seaside. As is often the case, there was a nice congregation of Black Turnstones on the rocks.

There were also good numbers of Surfbirds.

Heermann’s Gulls should be heading south very soon.

Our last stop was the Necanicum Estuary. This spot is very hit-or-miss, with either lots of birds or none. Today was closer to the latter. But along with the few California Gulls were several Caspian Terns still feeding young. Most Caspian Terns have already moved south, so it seems late to have begging fledglings still around.

The North Coast

July 30, 2012July 30, 2012 by John Rakestraw, posted in mammals, OR Birding Sites, rarities, seasonal movements

I made two trips to the northern Oregon Coast for my recent shorebird class. The “autumn” migration is well underway.

The Seaside Cove has a nice gathering of gulls. This California Gull is undergoing a rather extensive molt, I believe from second cycle to third. The severity of feather loss has actually created some interesting patterns.

This adult California Gull is showing a little wear, but nothing like the previous individual.

The Cove is a favorite hang-out for Heerman’s Gulls.

Young Heerman’s Gulls are a rich chocolate brown. I believe this is a second-cycle bird, given the smattering of gray feathers coming in.

This female Harlequin Duck was near the southern end of The Cove both days.

Black Turnstones, which spend the winter here, are back.

The best bird of the day Thursday was this Ruddy Turnstone, an uncommon migrant along the coast. Unfortunately, he did not stick around for my shorebird class field trip on Saturday.

Caspian Terns, seen here with California Gulls, were common on the beaches. Note the young tern in the center of the photo.

These Elk tracks were on the beach near the south jetty of the Columbia River at Fort Stevens State Park.

At high tide, the Hammond Boat Basin has been hosting large flocks of Marbled Godwits and Whimbrels (and an unidentified dowitcher species in the middle of this image). Similar roosts in Washington attract rare migrants every year. I hope the same is true for the Oregon side of the river.

Seaside, OR 8-4-11

August 4, 2011 by John Rakestraw, posted in OR Birding Sites, rarities, seasonal movements

I spent the day birding sites around Seaside, OR (Birding Oregon p. 121).

The tide was the lowest I have seen at The Cove, revealing its sandy bottom.

The low tide allowed lots of beach-combers to wander along the rocky edges, so the only shorebirds present was a small flock of Black Turnstones.

This is a Western Gull in very worn plumage. Note the black-tipped primary just starting to grow in. The lumpy neck on this bird was caused by the large sea star he had just swallowed.

Heerman’s Gulls are normally one of the most beautiful gull species, but this individual was also extremely worn.

These birds were in better shape.

California Gulls are starting to gather along the Oregon coast. This juvenile was keeping company with an adult Western Gull.

At the north end of town is the Necanicum Estuary, also at very low tide. The exposed mud and aquatic vegetation attracted nice numbers of shorebirds.

Least Sandpipers

Western Sandpiper

The rarest bird of the day was this Semipalmated Sandpiper.

Notice on these shorebird tracks that the toes are partially webbed, or semipalmated. So these tracks were made by either a Western Sandpiper, Semipalmated Plover, or Semipalmated Sandpiper.

These tracks don’t show any sign of webbing, so they were probably made by a Least Sandpiper.

The estuary is a favorite hang-out for Caspian Terns, here joined by California Gulls.

Shorebirds at Grays Harbor, WA

April 28, 2009 by John Rakestraw, posted in beyond OR, identification challenges, seasonal movements

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.

A Day at the Beach

August 11, 2008 by John Rakestraw, posted in OR Birding Sites

I took a client to the Necanicum Estuary (Birding Oregon p.122) last week. Shorebirds were surprisingly scarce on the mudflats. But the sand bars were covered with Caspian Terns. There was a huge concentration of these beautiful noisy birds resting, preening, diving for fish, and feeding their young. Here is a very small part of the flock.

Offshore, Brown Pelicans were actively feeding. The smaller dark birds are Heerman’s Gulls, which make their living stealing fish from Brown Pelicans.
