Wilson’s Phalarope, Phalaropus tricolor, falaropo pico largo (Spanish)
If Dorothy in The Wizard of Oz were a bird, she could have been a Wilson’s Phalarope. First, she wore brighter colors than any of the males, just like a female phalarope displays her resplendent plumage during breeding season to the dull gray males. Nothing discouraged Dorothy from her goal to reach the male wizard. A female Wilson’s Phalarope fights others to win a male.
Dorothy met all challenges to attain her goal to return to Kansas. Almost every Wilson’s Phalarope rests and replenishes at the largest interior marsh in the U.S. in central Kansas! It migrates from saline lakes of the Andean highlands and grasslands of South America to breed in southern Canada and northern U.S. prairie marshes and lakes.
Dorothy even survived a tornado with its rotating vortex. A phalarope makes its own vortex as it spins in water. This feeding behavior stirs insects, mosquito larvae, and crustaceans upward for it to pick up its food with its long, skinny bill. According to many resources, it feeds on the water’s surface. I saw its head plunge into the water to feed several times. In addition, it plucks its prey along the shore or while it swims. It’s a swimming shorebird!
Anyway, a flock may twirl at the same time close together. Someone named this grouping a swirl, a twirl, a whirl, or a whirligig. I would call it a whiriligiggle.
I’ll stop with the Dorothy similarities now.
In non-breeding season both sexes have yellow legs and are gray above and white below. During the breeding period, both genders have black legs, but only the female develops the black, chestnut, gray and white plumage. The breeding male is gray and white with a brownish neck. The 9-inch female phalarope is larger than the male and aggressively fights other females to select a male to mate. She guards her mate from other females and helps him select a nest site. He scrapes out a nest for her where she lays three to four eggs. Then she departs! (Guess the male had a fallow hope.)
She may select another male or several to mate with and then after her egg laying, leaves again. Each male incubates the eggs for 17 – 21 days. Perhaps the dull-colored male doesn’t attract predators while sitting on the nest. After the eggs hatch, only the male raises the chicks.
Hmmm, here is a quick summary. Unlike most bird species, the female Wilson’s Phalarope is larger and more brightly colored than the male, fights for and selects her mate, defends it, lays eggs, and doesn’t help with incubation or rearing the chicks. After that, she may mate again with several males and leaves each one to hatch the eggs and care for the chicks.
Maybe she is the wizard of odds.
American ornithologist, Alexander Wilson, gave the common name to the Wilson’s Phalarope. (Wonder where he got that name?) Phalarope means “coot foot” in Greek. This photo of the American Coot shows its lobed toes like those of a phalarope. If I photographed any phalarope toes, I’d call it “photoes”. Anyway, you get the picture; no ruby slippers here.
Several references stated this species is mostly silent but its call sounds like “work, work.” In this recording, it sounds to me like a dog bark.
This is an uncommon visitor to Merida and to the peninsula, but for four days, ten of these elegant shorebirds twirled, floated, darted along the shore, jabbed for food, and appeared to expend more energy than what they caught at Kai Lu um Park.
