John Value Dennis (1915/1916 – December 1, 2002)[1] was an American ornithologist and botanist.

Early life

[edit]

John V. Dennis was born in 1915 in Princess Anne, Maryland to Alfred and Mary Dennis (nee Value). Alfred Dennis passed away when Dennis was a teenager. Mary operated a boarding house in Washington, D.C..

Dennis was an undergraduate at George Washington University but his study was interrupted by World War II. During the war, he served as a radar technician with the Flying Tigers aircraft unit in Yunnan, China.

He finished his undergraduate education at the University of Wisconsin, obtaining a degree in political science. This was followed by a master's degree in botany from the University of Florida. He started, but did not complete, a PhD in ornithology at the University of Illinois.[2]

Work and contributions

[edit]

Botany

[edit]

In 1976, Dennis and fellow botanist Dr. C.R. Gunn wrote the guide World Guide to Tropical Drift Seeds and Fruits. Additionally, Dennis co-authored Sea-Beans from the Tropics: A Collector's Guide to Sea-Beans With Ed Perry.[2] While some of Dennis' work, like that on sea beans, the floatation of tropical drift seeds, are written from a more scientific perspective, Dennis' work also guided amateur gardeners and botanists, like The Wildlife Gardener, which describes how to design a garden that attracts local wildlife.[3] Dennis' work was often through a conservation lens, such as his book The Great Cypress Swamps, where he discusses the importance and history of swampland in the United States.[4]

Search for the Ivory-Billed Woodpecker

[edit]

Dennis studied woodpeckers extensively, and is credited with creating a repellent to keep woodpeckers off telephone polls.[2]

In particular he was interested in, and searched extensively for, the critically endangered ivory-billed woodpecker in Cuba and in old-growth forests of the southeastern United States.

In 1948, working with Davis Crompton, he traveled to the Oriente Province of Cuba and located a subspecies, called the Cuban ivory-billed woodpecker, after it had not been reported there for several years.[5] He reported a sighting in the Big Thicket of southeast Texas in 1966, which he called his "only good look at a North American ivorybill";[2] he returned in 1968, recording what he believed to be the bird's call.[2]

Many ornithologists, including James Tanner, generally regarded as the leading authority on ivory-bills, were skeptical of both the sighting and the recorded bird.[6][7] His sightings formed part of the basis for the creation of the Big Thicket National Preserve.[8][9]

Bird feeding

[edit]

He wrote A Complete Guide to Bird Feeding (1975), a book that increased interest in bird feeding.[1] This book was largely credited for increasing interest in bird feeding in the United States, and was reprinted in 1994.[1]

Personal life

[edit]

Dennis married his wife, Mary Alice in 1945.[10] They had two daughters, and a son.[1]

Dennis died of a brain tumor in 2002 at his home in Princess Anne, Maryland.[11]
