François Levaillant was a French author, explorer, naturalist, zoological collector, travel writer, and noted ornithologist. He described many new species of birds based on birds he collected in Africa and several birds are named after him. He was among the first to use colour plates for illustrating birds and opposed the use of binomial nomenclature introduced by Carl Linnaeus, preferring instead to use descriptive French names such as the bateleur for the distinctive African eagle.

Ornithology is a branch of zoology that concerns the study of birds. Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guilds, island biogeography, phylogeography, and conservation.
