Anthus spragueii

Sprague's pipit

Features
By Richard Javier

Geographic Range

Anthus spragueii breeds in the northern prairies of the Great Plains, it’s northern limit is Saskatchewan, with it’s western limit near the Rocky Mountains. Anthus spragueii can also be found in the Dakotas, western Minnesota, Montana, and parts of British Columbia. Anthus spragueii winters in Arizona, New Mexico, Texas, Oklahoma, Arkansas, Mississippi, Louisiana, and areas in Northern Mexico. It has also been observed in Michigan, western Ontario, Ohio, and Massachusetts.

Habitat

Sprague's pipits prefer grassland with few shrubs and high visibility. They prefer native grasses like wheatgrass, June grass, blue grama, Canby blue, green needle grass, smooth brome, and crested wheat.

Physical Description

Lacking some of the brighter colors found in other pipits, Sprague's pipits are well camouflaged in prairie grasses. The plumage is a tan color highlighted by streaks of white and black, with white outer tail feathers. Sprague's pipits have pinkish yellow legs, dark eyes, and a small cream colored beak. Females show an increase in mass during the mating season. Young are covered in gray down upon hatching and have transparent skin.

  • Sexual Dimorphism
  • sexes alike

Reproduction

Little is known about the mating systems of Anthus spragueii . During mating season Sprague's pipits are monogamous. Other pipits are known to perform aerial displays to attract mates.

In Saskatchewan Sprague's pipits take 3 to 4 months to raise a clutch. The season begins the second week of May and extends into July. Mates produce an average of 1.5 clutches per year with a clutch consisting of roughly 4.5 eggs. Nests are built on the ground in grassland near dense grass. Females collect dried grass 5 to 15 cm in length to weave into a nest. Sometimes females will build a canopy out of grass, creating a dome over the nest. The nest interior is approximately 7.6 cm in diameter, 3.8 cm in depth, with a 5.1 cm entrance hole. New nests are built for every brood. The incubation period is 13 to 14 days. There is little information about the age of sexual maturity in Sprague's pipits.

Females incubate the eggs over a 13 to 14 day period. During the pre-fledgling period (which lasts 10 to 11 days) Females provide all care. It has been suggested that males may take over care after young leave the nest.

Lifespan/Longevity

Little is known about the lifespan of Sprague's pipits.

Behavior

Sprague's pipits walk or run while foraging or avoiding predators. Males establish and defend territories with aerial displays. They circle over the territory, singing briefly then quickly flapping their wings. At the end of this show they dive low to the ground then pull up to land. Sprague's pipits are solitary during migration and winter, but form flocks during mating season. Sprague's pipits will reach a rear leg above the wing to scratch the head and perform anting and dusting as self maintenance.

Home Range

Sprague's pipits establish territories during the breeding season. Males establish their territory through an aerial display in which they circle over the territory.

Communication and Perception

Sprague's pipits generally only make calls that are short "squicks." Only males are known to sing, and only during their aerial display. Male songs are high pitched and last 2 to 3 seconds. Nestlings can make noises at age 10 to 11 days.

Food Habits

Sprague's pipits eat mostly arthropods during breeding season, and some seeds too. They forage in grasses on their own during the daytime. They eat spurge seeds, grasshoppers, crickets, false cinch bugs, weevils, stink bugs, ants, leaf beetles, beetles, and caterpillars. Females bring small invertebrates to the young to eat.

  • Animal Foods
  • insects
  • Plant Foods
  • seeds, grains, and nuts

Predation

Little is known about predators of Sprague's pipits, but carnivorous mammals, such as weasels, and snakes are suspected as predators of eggs and nestlings. Raptors may take fledglings and adults.

Ecosystem Roles

Broods of Sprague's pipits are parasitized by brown-headed cowbirds, but less so than other prairie-dwelling birds. They are also parasitized by the feather mites Proctophyllodes anthi and P. polyxenus . Sprague's pipits forages for insects and also feed on seeds.

Commensal/Parasitic Species

Economic Importance for Humans: Positive

Sprague's pipits have no known economic importance to humans, aside from their role as parts of healthy, prairie ecosystems.

Economic Importance for Humans: Negative

There are no adverse effects of Sprague's pipits on humans.

Conservation Status

Sprague's pipits are considered vulnerable because of a rapid population decline of about 32% that has been documented since the 1970's. The major threats to this species are considered habitat loss and degradation resulting from land conversion to agriculture.

Other Comments

According to The Birds of North America, Sprague's pipits are "one of the least-known birds in North America." Named after Isaac Sprague, who discovered these birds near Fort Union, N.D. in June of 1943.

Nearctic

living in the Nearctic biogeographic province, the northern part of the New World. This includes Greenland, the Canadian Arctic islands, and all of the North American as far south as the highlands of central Mexico.

World Map

native range

the area in which the animal is naturally found, the region in which it is endemic.

temperate

that region of the Earth between 23.5 degrees North and 60 degrees North (between the Tropic of Cancer and the Arctic Circle) and between 23.5 degrees South and 60 degrees South (between the Tropic of Capricorn and the Antarctic Circle).

terrestrial

Living on the ground.

tropical savanna and grassland

A terrestrial biome. Savannas are grasslands with scattered individual trees that do not form a closed canopy. Extensive savannas are found in parts of subtropical and tropical Africa and South America, and in Australia.

savanna

A grassland with scattered trees or scattered clumps of trees, a type of community intermediate between grassland and forest. See also Tropical savanna and grassland biome.

temperate grassland

A terrestrial biome found in temperate latitudes (>23.5° N or S latitude). Vegetation is made up mostly of grasses, the height and species diversity of which depend largely on the amount of moisture available. Fire and grazing are important in the long-term maintenance of grasslands.

agricultural

living in landscapes dominated by human agriculture.

endothermic

animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestor; the fossil record does not distinguish these possibilities. Convergent in birds.

bilateral symmetry

having body symmetry such that the animal can be divided in one plane into two mirror-image halves. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Synapomorphy of the Bilateria.

monogamous

Having one mate at a time.

iteroparous

offspring are produced in more than one group (litters, clutches, etc.) and across multiple seasons (or other periods hospitable to reproduction). Iteroparous animals must, by definition, survive over multiple seasons (or periodic condition changes).

seasonal breeding

breeding is confined to a particular season

sexual

reproduction that includes combining the genetic contribution of two individuals, a male and a female

oviparous

reproduction in which eggs are released by the female; development of offspring occurs outside the mother's body.

altricial

young are born in a relatively underdeveloped state; they are unable to feed or care for themselves or locomote independently for a period of time after birth/hatching. In birds, naked and helpless after hatching.

diurnal
  1. active during the day, 2. lasting for one day.
motile

having the capacity to move from one place to another.

migratory

makes seasonal movements between breeding and wintering grounds

tactile

uses touch to communicate

acoustic

uses sound to communicate

chemical

uses smells or other chemicals to communicate
