Natural History
In 2010, the estimate of cormorant population, considered a nuisance, ranged from 14,000 to 16,000. A Fish and Wildlife commissioner said that the ideal population would be 3,300 or about 3 per 1 square kilometre (0.39 sq mi). Cormorants had disappeared from the lake (and all northern lakes) due to the use of DDT in the 1940s and 1950s.
Ring-billed gulls are also considered a nuisance. Measures have been taken to reduce their population. Authorities are attempting to encourage the return of black crowned night herons, cattle egrets, great blue herons, which disappeared during the time DDT was being used.

“The use of natural history is to give us aid in supernatural history: the use of the outer creation, to give us language for the beings and changes of the inward creation.”
—Ralph Waldo Emerson (1803–1882)
“Fate then is that necessity by which a certain result will surely be brought to pass according to the natural course of events however we may vary the particular circumstances which precede the event.”
—Charles Sanders Peirce (1839–1914)
“We are told that men protect us; that they are generous, even chivalric in their protection. Gentlemen, if your protectors were women, and they took all your property and your children, and paid you half as much for your work, though as well or better done than your own, would you think much of the chivalry which permitted you to sit in street-cars and picked up your pocket- handkerchief?”
—Mary B. Clay, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4, ch. 3, by Susan B. Anthony and Ida Husted Harper (1902)
