Whooping Crane
Grus americana
| Conservation status | Endangered. Whoopers once nested on the northern prairies south to present-day Iowa and Illinois, but they disappeared as settlers moved in. As recently as 1912, about 90 birds wintered at various points in coastal Texas and Louisiana, and there was a nonmigratory population in southwestern Louisiana as well. By 1941 the Texas wintering flock was down to only 15 birds (another six were still resident in Louisiana, but that flock soon dwindled away). After 1941, numbers very gradually rose again, helped by protection on the wintering grounds and public education against shooting; by the mid-1990s, the Texas wintering flock approached 150. Attempts to start a new flock farther west (by putting Whooper eggs under Sandhill Cranes in Idaho) failed, but in the 1990s a new project aimed to start a nonmigratory flock in Florida, using birds raised in captivity. Most recently, an ambitious project has established a new flock that summers in Wisconsin, with young birds raised and then trained to follow an ultralight aircraft to Florida for their first southward migration. |

| Habitat | Muskeg (summer); prairie pools, marshes. Current breeding habitat is in remote northern forest, in areas of muskeg (swampy coniferous woods with numerous lakes and ponds). Formerly also nested in prairie marshes. Winters in coastal marsh, where adult pairs and families defend territories, returning to same territory each winter. |

Feeding Behavior
See family introduction.
Eggs
2, sometimes 1 or 3. Olive-buff, spotted with dark brown. Incubation is by both sexes, 29-31 days; female usually incubates at night. Young: Downy young leave nest within a few hours after hatching. Both parents feed young. Two eggs typically hatch, but very rarely or never does more than one young bird survive. Young is able to fly at about 3 months after hatching.
Young
Downy young leave nest within a few hours after hatching. Both parents feed young. Two eggs typically hatch, but very rarely or never does more than one young bird survive. Young is able to fly at about 3 months after hatching.
Diet
Omnivorous. In winter, eats insects, shrimp, crabs, clams, snails, frogs, snakes, small fish, seeds, acorns, roots, berries. Summer diet not well known, probably a similarly wide variety of animal and plant matter.
Nesting
In courtship, pairs "dance," leaping into air repeatedly with flapping wings, bills pointed upward, giving bugling calls; dance has a dignified look. Other displays include bowing, tossing tufts of grass in the air, and loud trumpeting or "whooping" calls. Nest site is on ground, typically on marshy island in lake or pond. Nest (built by both sexes) is a large mound of grass, weeds, mud, with depression at center.

Songs and Calls
A trumpet-like call that can be heard for several miles.How climate change could affect this bird's range
In the broadest and most detailed study of its kind, Audubon scientists have used hundreds of thousands of citizen-science observations and sophisticated climate models to predict how birds in the U.S. and Canada will react to climate change.

Each map is a visual guide to where a particular bird species may find the climate conditions it needs to survive in the future. We call this the bird’s “climatic range.”
The colors indicate the season in which the bird may find suitable conditions— blue for winter, yellow for summer (breeding), and green for where they overlap (indicating their presence year-round).
The darker the shaded area, the more likely it is the bird species will find suitable climate conditions to survive there.
The outline of the approximate current range for each season remains fixed in each frame, allowing you to compare how the range will expand, contract, or shift in the future.
The first frame of the animation shows where the bird can find a suitable climate today (based on data from 2000). The next three frames predict where this bird’s suitable climate may shift in the future—one frame each for 2020, 2050, and 2080.
You can play or pause the animation with the orange button in the lower left, or select an individual frame to study by clicking on its year.
