Population Size
On Oahu, Maui, Molokai and Kaua’i, the Hawaiian coot was previously abundant in coastal brackish and fresh-water ponds, streams, and marshes; however, the first censuses conducted in the 1950s and 1960s detected fewer than 1,000 birds statewide. Since the 1960s, the interannual population size has fluctuated from less than 1,000 birds to over 3,000, and appears to be gradually increasing. Biannual surveys conducted by the Hawaiian Department of Land and Natural Resource’s Division of Forestry and Wildlife (DOFAW) found that between 1998 and 2003 the inter-island coot population averaged 2,100 birds, ranging between 1,500 and 3,000 birds. Recent surveys estimated winter populations fluctuating around 1,500 birds and a summer population fluctuating around 2,000 birds.

Famous quotes containing the words population and/or size:
“The population of the world is a conditional population; these are not the best, but the best that could live in the existing state of soils, gases, animals, and morals: the best that could yet live; there shall be a better, please God.”
—Ralph Waldo Emerson (1803–1882)
“To believe her limited in range because she was harmonious in method is as sensible as to imagine that when the Atlantic Ocean is as smooth as a mill-pond it shrinks to the size of a mill-pond.”
—Rebecca West (1892–1983)
