Harold F. Mayfield
Harold Ford Mayfield (25 March 1911 – 27 January 2007) was an American business executive and amateur ornithologist who made a major study of Kirtland's warbler and worked for the preservation of their breeding areas. During his study of the warbler, he introduced a standardized measure of nesting success based on his professional experience in industry and from his training in mathematics. This method now widely known as the Mayfield Method involves probability calculations that take into account nests that the observer was unable to locate. Prior to his work, ornithologists used naïve approaches based on fractions of number of successful young or nests from a total of nests that they had found. Life and work Harold was born as James Blegen to John Blegen and Ida Thorberg before they were married. Due to the social stigma of the time he was given away for adoption and raised by Frank and Mae Ford Mayfield in Iowa. He grew up in Alton, Illinois and showed talent as a basketball ...

Kirtland's Warbler
Kirtland's warbler (''Setophaga kirtlandii''), also known in Michigan by the common name jack pine bird, or the jack pine warbler, is a small songbird of the New World warbler family ( Parulidae), named after Jared Potter Kirtland, an Ohio doctor and amateur naturalist. Nearly extinct just 50 years ago, populations have recovered due to conservation efforts. It requires large areas, greater than 160 acres (65 hectares), of dense young jack pine for its breeding habitat. This habitat was historically created by wildfire, but today is created through the harvest of mature jack pine, and planting of jack pine seedlings. The population of the species spends the spring and summer in their breeding range in Ontario, Wisconsin or Michigan, especially the northeastern Lower Peninsula of Michigan, and winters in The Bahamas, Cuba, Hispaniola and the Turks and Caicos Islands. Taxonomy This species was first recorded at a relatively late date for a bird from the eastern USA. The first sp ...

American Ornithologists’ Union
The American Ornithological Society (AOS) is an ornithological organization based in the United States. The society was formed in October 2016 by the merger of the American Ornithologists' Union (AOU) and the Cooper Ornithological Society. Its members are primarily professional ornithologists, although membership is open to anyone with an interest in birds. The society publishes the two scholarly journals, ''The Auk'' and '' The Condor'' as well as the '' AOS Checklist of North American Birds''. In 2013, the American Ornithologists' Union announced a close partnership with the Cooper Ornithological Society, including joint meetings, a centralized publishing office, and a refocusing of their respective journals to increase efficiency of research. In October 2016, the AOU announced that it was ceasing to operate as an independent union and was merging with the Cooper Ornithological Society to create the American Ornithological Society.

Cornell University
Cornell University is a private statutory land-grant research university based in Ithaca, New York. It is a member of the Ivy League. Founded in 1865 by Ezra Cornell and Andrew Dickson White, Cornell was founded with the intention to teach and make contributions in all fields of knowledge—from the classics to the sciences, and from the theoretical to the applied. These ideals, unconventional for the time, are captured in Cornell's founding principle, a popular 1868 quotation from founder Ezra Cornell: "I would found an institution where any person can find instruction in any study." Cornell is ranked among the top global universities. The university is organized into seven undergraduate colleges and seven graduate divisions at its main Ithaca campus, with each college and division defining its specific admission standards and academic programs in near autonomy. The university also administers three satellite campuses, two in New York City and one in Educatio ...

Alton, Illinois
Alton ( ) is a city on the Mississippi River in Madison County, Illinois, United States, about north of St. Louis, Missouri. The population was 25,676 at the 2020 census. It is a part of the River Bend area in the Metro-East region of the Greater St. Louis metropolitan area. It is famous for its limestone bluffs along the river north of the city, as the former location of the state penitentiary, and for its role preceding and during the American Civil War. It was the site of the last Abraham Lincoln and Stephen Douglas debate in October 1858. The former state penitentiary in Alton was used during the Civil War to hold up to 12,000 Confederate prisoners of war. History Although Alton once was growing faster than the nearby city of St. Louis, a coalition of St. Louis businessmen planned to build a competing town to stop Alton's expansion and bring business to St. Louis. The resulting town was Grafton, Illinois. Many blocks of housing in Alton were built in the Victorian ...
