[Dunlin resting above the wave line]
Shorebirds are some of our latest migrants in the northern reaches of Minnesota. Though flocks may begin appearing in late April, the mass movement doesn’t peak until late May. And so I took several opportunities to scope out the migration along one of Lake Superior’s most beautiful beaches…Wisconsin Point. Along with its “sister spit,” Park Point in Duluth, Minnesota, they create the world’s longest freshwater sand spit…nearly 10 miles long! Shorebirds moving north to their Arctic breeding grounds find the wide sand beaches and immense body of water familiar sights, and are likely reminded of their coastal wintering grounds in the southern U.S., Central and South America.

My technique in photographing shorebirds (shown in my video, Get Close & Get the Shot) is to move slowly in plain sight of the waders, crawling along the beach, then laying down in the sand as they get near. I try to get as close to eye level as possible (without grinding sand into my camera equipment!) as this gives a more intimate portrait. The success ration is not high as they often turn and start feeding in the opposite direction or scurry past so fast that getting a shot is almost impossible.

[Dunlin sleeping]
Considering that this Dunlin may have already flown a thousand miles from wintering beaches in the southeastern U.S. or Atlantic Coast, it’s no wonder she’s tuckered out. And she’s got a couple thousand more miles to go to get to breeding grounds in northern Canada and the North Slope of Alaska.

Dunlin are easy to identify. They are the ones that look like their bellies have been dipped in black ink. Also note their longer drooping bill.

We normally see Sanderlings in their “winter whites,” their pale non-breeding plumage. But this bird is already acquiring its reddish breeding plumage.

This mixed flock of shorebirds contains Sanderlings, Dunlin and a rather rare visitor to Lake Superior…the Red Knot (the largest bird). I usually only see one or two of these each spring, and some years I miss them completely, so this was a real treat.

[Common Tern]
Terns seemingly float on buoyant wingbeats as they patrol shorelines for fish. Their head is angled down scanning the water for a likely meal and once a fish is spotted, they instantly tuck their wings in and go into a plummeting vertical dive into the water.

As part of their courtship the male Common Tern flies around with a small fish which he offers to the female. Strangely, these terns LOVE to nest on dredge material…sand and dirt dug up from the Duluth-Superior bay and piled on to land. Due to this preference, Common Terns formerly nested right in the Port Terminal of Duluth, which was essentially built entirely on dredge. But an effort to move them out of this busy industrial area had little success until Interstate Island (a tiny 8 acre island in the St. Louis Estuary just upstream of the Blatnik Bridge which is divided by the Minnesota-Wisconsin state lines) was bulldozed and became an ideal sanctuary off limits to humans. Unfortunately, Ring-billed Gulls rule the island with 13,000 nest in a recent census. Common Tern nests numbered about 200. This is only one of two nesting locations in the Lake Superior region. Commons are listed as Endangered in Wisconsin and Threatened in Minnesota.

I LOVE Caspian Terns! Maybe it’s that I only see them passing through in late May, or maybe their exotic name (they also range across parts of Europe and Russia including the Caspian Sea) These mega-terns are giant versions of the diminutive Commons that perched nearby. Their pterodactyl-like croak signals their presence with authority! Like the Common Terns, Caspians live almost entirely on fish.

[Redhead pair on the bayside of Wisconsin Point]
Redheads are attractive ducks of our western and midwestern pothole prairies. While not rare, they are certainly not common either, and always a treat to see. This flock of four was even tolerant of my semi-stealthy approach along the bank of the bay.

[American Redstart
Hiking back to the car on the inland side of the wind-whipped point we found a very cooperative warbler, the American Redstart, proudly and emphatically defending his territory in song.
