The Northern Pintail is protected by the Migratory Bird Treaty Act, although there is a general hunting season for the bird throughout the United States.
US Migratory Bird Act: protected
US Federal List: no special status
CITES: no special status
State of Michigan List: no special status
IUCN Red List of Threatened Species: least concern
Like other waterfowl species, Pintail damage grain crops and cost farmers a considerable amount of money every year.
Negative Impacts: crop pest
Northern Pintail are one of the most sought after ducks by duck hunters throughout their habitat. During duck season, hunters spend lots of money on hunting licenses, sporting goods and travel arrangements to towns that live near the migration flyways, and add a considerable amount of revenue to towns’ economy.
Positive Impacts: food
Pintail feed on grain fields, including rice, wheat, barley, and oats. They also feed on foods that naturally occur, such alkali and hardstem bulrush seeds, sago pondweeds, insects, cladocera, and widgeon grass.
(Bellrose 1980)
Animal Foods: insects; terrestrial non-insect arthropods
Plant Foods: leaves; seeds, grains, and nuts
Primary Diet: omnivore
Northern Pintail, also called sprig, are found throughout the world. During the summer they are found mainly in the Northern Hemisphere as far south as Poland and Mongolia in Eurasia and California in North America. In the winter, they migrate to the Southern Hemisphere, including parts of Africa and all of Mexico. Some Pintail even fly all the way to Hawaii to spend the winter.

Biogeographic Regions: nearctic (Native ); palearctic (Native ); oceanic islands (Native )
Pintail are found in marshes, ponds, lakes, rivers, canals, and grain fields, such as rice, oats, wheat, and barley.
(Palmer 1976)
Habitat Regions: temperate ; terrestrial
Terrestrial Biomes: forest
Aquatic Biomes: lakes and ponds; rivers and streams

Other Habitat Features: agricultural ; riparian
Around three-quarters of hatchlings live long enough to fledge, and not more than half of the remaining birds live to produce young of their own.
(Palmer 1976; Gooders, Boyer 1986)
Average lifespan
Status: wild: 267 months.
The adult male Northern Pintail is between 23 to 30 inches (58.5 to 76 centimeters) in length and weighs 1 to 3 pounds (454 to 1362 Grams). Adult females measure 20 to 25 inches (51 to 63.5 centimeters) and weighs 1 to 2.5 pounds (454 to 1135 g). Males have a dark brown head and white breast with a white streak extending up the side of its head. From their back extending down and around their bellies, they have black and white speckled feathers with a yellow patch of feathers just above and behind their feet. Males also have a long, thin tail feather that can measure as much as 10 centimeters (4 inches) long. This feather narrows down to a sharp point and is where they get their name. The female has more of a drab, gray color to her feathers to help camouflage her as she sits on her nest, and her pin tail feather is only about one-quarter the length of the males.
These ducks have bluish-gray bills and they have longer necks than most other dabbling ducks, which makes them superb at feeding in deeper water.
Immature pintails measure from 53 to 68.5 centimeters (21 to 27 inches) and weigh 1 to 3 pounds (454 to 1362 g). Their feathers have more of a buff color to them; their bills are dark; and their heads range in color from dark brown to tan, while their bellies are speckled white and brown. Their tail feathers are dark, with cream colored edges and their feet are grayish green.

Other Physical Features: endothermic ; bilateral symmetry
People are the main predators of adult pintails, but they are also preyed upon by bobcats and coyotes. To avoid predation they take flight.
Farmers, during the process of working in their fields, destroy nests. Crows, magpies, gulls, skunks, ground squirrels, coyotes, foxes, badgers, and raccoons also destroy nests and eat the eggs.
(Bellrose 1980)
Known Predators:
During courtship, the male, all the while whistling, will swim close to the female with his head down and tail up to impress the hen. If there is a group of males all courting the same female, the males will chase the female in flight. The males will lose track of her one by one, until only one male is left, and to his victory comes the opportunity to leave his legacy. Copulation takes place in the water and the female gets ready by laying her body close to the ground. The male then starts bobbing his head up and down. He then mounts the female and takes the feathers on the back of her head in his mouth. After he finishes, he lifts his head and back up and whistles. (Gooders & Boyer 1986; Soothill & Whitehead 1988; Palmer 1976)
Mating System: monogamous
Mating season is in early May, and if predators destroy the hen’s eggs, she can replace the clutch as late as the end of July, a process called double clutching. Pintail become sexually mature at 1 year old. (Soothill, Whitehead 1988; Palmer 1976)
A Northern Pintail hen lays 7 to 9 cream colored eggs in May usually laying one egg per day, and the hen alone will incubate them for 22 to 24 days. After the chicks hatch, the hen will lead them to the nearest body of water where they will search for dead insects on the surface of the water. The chicks will attain flight in 46 to 47 days after hatching and the family will stay together until the hen re-grows the feathers needed to fly and she leaves her chicks.
