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?

Range of the American White Pelican in North America [from Cornell]
“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].

Population Information:
- North America population estimate: 67,030 breeding pairs (1998-2001; King and Anderson 2005)
- Minnesota population estimate: 15,824 breeding pairs breeding at 16 different colony sites (Wires, Haws and Cuthbert 2005: The Double-crested Cormorant and American White Pelican in Minnesota: A Statewide Status Assessment)
- Minnesota has one of the largest North American colonies at Marsh Lake; over 80% of the state’s population occurs in this location

“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]

- California Condor—109″
- American White Pelican—108″
- Greater Frigatebird—90″

“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].
