| | American Coots (Site not responding. Last check: 2007-10-21) |
 | | To signal their social intentions coots vary body postures, adjust the position of the white undertail coverts, alter the degree to which they arch the wings over the back, change the angle of erect neck feathers and, when aroused, swell the frontal "nose" shield. |
 | | Coots communicate distress to each other by exposing their undertail coverts or displaying a swollen shield when alarmed by potential dangers such as hawks, airplanes, or predatory mammals. |
 | | In Hawaii, for example, where coot numbers were reduced to 1,500 by the mid-1970s and the island population was considered endangered, their decline was also an indicator of the rapid disappearance of island wetlands, an important habitat for many other Hawaiian species. |
