Ornithology is a branch of zoology that concerns the study of birds. [1] Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. [2] It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support.
Although the term "bird of prey" could theoretically be taken to include all birds that actively hunt and eat other animals, [4] ornithologists typically use the narrower definition followed in this page, [5] excluding many piscivorous predators such as storks, cranes, herons, gulls, skuas, penguins, and kingfishers, as well as many primarily ...
The following is a timeline of ornithology events: Francis Willughbys Ornithologia. This work is considered to be the beginning of scientific ornithology in Europe, and which revolutionized ornithology, by organizing species according to their physical characteristics.
A turning point came in the early twentieth century with the writings of Gerhard Heilmann of Denmark.An artist by trade, Heilmann had a scholarly interest in birds and from 1913 to 1916, expanding on earlier work by Othenio Abel, [12] published the results of his research in several parts, dealing with the anatomy, embryology, behavior, paleontology, and evolution of birds.

This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Other research has shown that the physics involved in cursorial flight would not make this a likely answer to the origin of avian flight. Once flight speed is obtained and Archaeopteryx is in the air, drag would cause the velocity to instantaneously decrease; balance could not be maintained due to this immediate reduction in velocity.
Although the word "beak" was, in the past, generally restricted to the sharpened bills of birds of prey, [1] in modern ornithology, the terms beak and bill are generally considered to be synonymous. [2] The word, which dates from the 13th century, comes from the Middle English bec (via Anglo French), which itself comes from the Latin beccus. [3]
The start of the Ornithological Dictionary's article on the cirl bunting. The entire body of the book is arranged as a dictionary from Aberdevine ('Vide Siskin'.) on page 58 (the pages are however not numbered in the original [a]) to Yelper ('Vide Avoset'.) on page 687. Since the book does not have a continuous narrative to summarise, the ...
