The American Bittern (Botaurus lentiginosus), a marsh bird of the heron family, inhabits summer shallow freshwater wetlands across much of Canada and the northern United States. Winter migration, finds the Bittern primarily in the southern United States and Mexico. The Bittern averages a 3-foot wingspan, body weight of 1 pound and a tip of the beak to end of tail length of 2.5 feet. In comparison, the Bitterns well know larger cousin the Great Blue Heron, boasts a 6-foot wingspan and body weight of 8 pounds.
The Bittern’s feet appear oversized for its relatively diminutive body, however, like snowshoes function, the large feet allow the Bittern to walk across unstable marsh environments without sinking.
A master of camouflage, both the male and female
Bittern boast plumage of tan feathers, accentuated by white, brown and black streaks, making it almost impossible to locate in the reeds and cattails of its favored habitats. When frightened, the Bittern points it’s bill skyward, making its head, neck and body mimic the marshy background.
American Bittern lay between 3-5 eggs that the female incubates for at least 24 days. Young usually leave the nest after about two weeks but are not able to fly for around a month and a half.
Birdwatchers hoping to see a Bittern are more likely to first hear this elusive bird than see it. By arriving at a marsh at dawn or dusk and listen for the bitterns booming song, a loud snapping followed by a noise sounding like water dripping into a bowl from a leaky faucet, will help birdwatchers locate this sometime elusive avian.
In the United States, the destruction of wetland habitat has caused a marked yearly decline in the population of the American Bittern. Despite being protected, under the United States Migratory Bird Treaty Act of 1918, habitat loss is slowly destroying this species. The American Bittern’s survival depends on the preservation of wetlands and continued study of its biology and behavior.
