Pelican Stopover in the North Woods

Every spring for the last several years, a flock of American White Pelicans has stopped over along the St. Louis River at Fond du Lac, Duluth, Minnesota. Here they find a couple ideal loafing islands in mid river and I suppose, good fishing. Arriving in late April, they usually depart by mid May. In 2017, they showed up on April 19th and departed by mid May. They are easily visible from the Fond du Lac Bridge that joins Minnesota and Wisconsin. I imagine these flocks are headed to major breeding colonies at Lake of the Woods, Minnesota, but I’m not positive.

A flock of American White Pelicans has made the St. Louis River at Fond du Lac, Duluth, Minnesota (and nearby Wisconsin portion of the river) a spring stopover on their way to breeding grounds farther north. There are fewer than 70 breeding colonies in North America (50 in Canada, 18 in the U.S.), with 3 in Minnesota. Of course, some of these colonies are massive! They are considered a Species of Special Concern in Minnesota.

“The American white pelican formerly ranged throughout much of Minnesota, with nesting documented as far east as Aitkin County in 1904. The species declined in the late 19th and early 20th centuries, largely due to human persecution (Wires et al. 2005). There were no reports of nesting in the state after 1878 (Roberts 1932) until 70 nests were found at Marsh Lake in Big Stone and Lac qui Parle counties in 1968. Nesting was limited to less than 10 colonies in the early 1980s, and the species was subsequently listed as special concern in 1984. In the 1990s, nesting was confirmed in several additional areas. Large numbers of non-breeding adults are also regularly seen on other Minnesota lakes throughout the summer. Although there is evidence of an increasing population in Minnesota, it might best be viewed as a recolonization of its former range (Wires et al. 2005). Colonial breeding habits and occupancy of a small number of breeding sites make white pelicans particularly vulnerable to decline, meriting special concern status. The Marsh Lake colony is the largest known colony in North America, giving it continent-wide significance (Wires et al. 2005).” [from http://www.dnr.state.mn.us]

“Pelicans are big birds that can overheat when they’re out in the hot sun. They shed heat by facing away from the sun and fluttering their bill pouches—which contain many blood vessels to let body heat escape. Incubating parents may also stretch their wings wide to aid cooling.” [from http://www.allaboutbirds.org]. I’m actually not sure if this is what is happening in this photo as at this exact moment a Ring-billed Gull flew directly over this group’s heads…Could it be an aggressive posture?

“Pelicans are skillful food thieves. They steal from other pelicans trying to swallow large fish and are successful about one-third of the time. They also try to steal prey from Double-crested Cormorants that are bringing fish to the surface. In their dense nesting colonies, some birds even steal the food that a parent on an adjacent nest has disgorged for its young.” [from http://www.allaboutbirds.org].

“Contrary to cartoon portrayals and common misconceptions, pelicans never carry food in their bill pouches. They use them to scoop up food but swallow their catch before flying off” [from http://www.allaboutbirds.org].

“American while pelicans are a monogamous species, and most likely pair each year on their breeding grounds. Adults begin breeding when three years old. They perform a variety of flying and walking courtship displays, and select a nest site within a dense colony. Colonies are mainly located on isolated islands, also occupied by gulls and cormorants. A pelican colony can consist of thousands of birds (Evans and Knopf 1993). After courtship, each pair builds a nest by scraping gravel, soil, or vegetation to form a shallow depression. The bottom of the nest may contain little or no insulation. A clutch of two eggs is common. Both males and females take turns to continuously incubate and guard the eggs until they hatch, usually about 30 days later. The young are altricial. The first chick to hatch frequently harasses the younger sibling, causing it to leave the nest early or move to an area of the nest where it is fed less often. Second chicks often die of starvation, predation, or exposure. Adults feed chicks by regurgitating food into their beak pouch, where it is made accessible to the chicks. Parents continuously brood nestlings for about 17-25 days. As parents begin leaving nests unattended, groups of chicks huddle together for warmth, forming a pod or creche. These pods may also serve as protection from predators (Evans and Knopf 1993). The young walk from the nest at about 26 days, and fly after 62-63 days. [from http://www.dnr.state.mn.us]

According to The Sibley Guide to Birds, here are the North American birds with WINGSPANS OVER SEVEN FEET.

  1. California Condor—109″
  2. American White Pelican—108″
  3. Greater Frigatebird—90″
  4. Whooping Crane—87″
  5. Short-tailed Albatross—87″
  6. Black-footed Albatross—84″

  9. Golden Eagle—79″
  10. Brown Pelican—79″
  11. Laysan Albatross—78″
  12. Sandhill Crane—77″
  13. Mute Swan—76″
  14. Great Blue Heron—72″

“American White Pelicans cooperate when feeding. Sometimes, large groups gather in wetlands. They coordinate their swimming to drive schooling fish toward the shallows. The pelicans can then easily scoop up these corralled fish from the water.” [from http://www.allaboutbirds.org].

Northwest Minnesota—Part 1: Agassiz & Thief Lake WMAs, June 12-13, 2016

My first stop on this mid June excursion was Agassiz National Wildlife Refuge in far northwest Minnesota. It was a gloomy, windy, rainy day in the aspen parklands but I had to make the most of a photographically-poor situation. Down a side road on the refuge I found a spot where Forster’s Terns were making pass after pass above a flooded creek/drainage ditch. At first I simply cranked up the ISO and took many shots to freeze these elegant birds in flight. But the gray skies got grayer, and the gloom got gloomier, so I altered my technique; now I switched to Shutter Priority mode and attempted to get some slow panning shots. My favorite Forster’s photos are below.

I used Manual exposure setting as I wanted the image exposed properly for the white bird. And since the background was changing as the bird flew (from light sky to dark green leaves) I couldn’t trust Aperture Priority to get the right exposure.

EIGHT small fish in ONE DIVE! An amazing feat to accomplish in a head-first plunge that lasts one second max. There must have been very tight schools of fish to be so successful.

I love this place in late spring/early summer. It is secluded, has tons of bird life, and a very cool “observation mound” from which you can scan the ginormous cattail marsh.

This photo was a real surprise success..and I didn’t realize it until I got home and viewed it on the iMac. I really like the odd “M.C Esher-esque” juxtaposition of the bird and the “upside down” cattails (reflection). It was also a very pleasant surprise that the Black Tern’s wings mimicked the angle of the cattails without overlapping with them.

Franklin's Gull Thief Lake WMA Marshall Co MN IMG_1069Franklin’s Gull in flight over Thief Lake WMA.
My number one goal on this leg of the trip was to photograph what I consider to be one of the most beautiful gulls in North America…the Franklin’s Gull. I love the mat black head, white eye-ring and blood red bill. And the fact that they are not a gull I see that often makes them even more special.

Flocks of Franklin’s Gulls forage in neighboring farm fields during the day. This flock was making repeated flights to catch aerial insects. I did not notice the bug until I got home and viewed this image large. I used Shutter Priority in order to make sure I froze the motion of the flying birds (though, this image is a bit soft due to movement so I should have used 1/2000 or 1/1600 second)
