Birds Flee in the Face of Fracking
In North Dakota, several species are responding to the recent natural gas boom by moving far away from active wells.

Calcarius ornatus
Conservation status | Has disappeared from some former nesting areas, but still fairly widespread and common. |
---|---|
Family | Longspurs and Snow Buntings |
Habitat | Plains, prairies. Breeds in the general region of shortgrass prairie, but in areas of slightly longer grass and scattered taller weeds. Winters in shortgrass prairies and fields. Overlaps broadly in range with Thick-billed Longspur, but tends to occur in areas with taller and denser grass. |
Forages while running and walking on ground, picking up items from soil or from plants. After flushing insects from ground, sometimes will chase them, even in short flights.
4-5, sometimes 3, rarely 6. Whitish, marked with brown, black, purple. Incubation is by female only, about 10-13 days. Young: Both parents feed the nestlings. Young leave the nest about 10 days after hatching; can fly well by a few days later. 2 broods per year.

Mostly seeds and insects. Seeds may make up close to half of summer diet of adults, and great majority of winter diet; included are seeds of weeds and grasses. Also feeds on many insects in summer, including grasshoppers, crickets, beetles, and others, as well as spiders. Young are fed mostly insects.
To defend nesting territory, male performs flight-song display, fluttering up about 20', flying in undulating circles while singing, then fluttering down again. Also often sings from a raised perch. Nest site is on ground, often at base of grass clump or weed, or next to dried cow manure or other object. Placed in shallow depression, either a natural hollow or one scraped out by bird, so that rim of nest is about level with ground. Female builds nest, a shallow cup of grass, lined with finer grass and sometimes with rootlets, feathers, or animal hair.
Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.
Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures.
