Bird collections

Bird collections are curated repositories of scientific specimens consisting of birds and their parts. They are a research resource for ornithology, the science of birds, and for other scientific disciplines in which information about birds is useful. These collections are archives of avian diversity and serve the diverse needs of scientific researchers, artists, and educators. Collections may include a variety of preparation types emphasizing preservation of feathers, skeletons, soft tissues, or (increasingly) some combination thereof. Modern collections range in size from small teaching collections, such as one might find at a nature reserve visitor center or small college, to large research collections of the world’s major natural history museums, the largest of which contain hundreds of thousands of specimens. Bird collections function much like libraries, with specimens arranged in drawers and cabinets in taxonomic order, curated by scientists who oversee the maintenance, use, and growth of collections and make them available for study through visits or loans.

The roots of modern bird collections are found in the 18th- and 19th-century explorations of Europeans intent on documenting global plant and animal diversity. It was a fashion to collect and display natural curiosities in Victorian England. Some wealthy cabinet naturalists were able to amass large collections using networks of field collectors. These early collections were not intended for scientific study and the collectors gave importance to aesthetics rather than scientific value. It grew into a more scientific pursuit much later.

Early scientific bird collections included those belonging to Pallas and Naumann in Germany, Latham and Tunstall in England and Adanson in France. Collections grew in size with increasing maritime activity, exploration and colonialism. For example, Charles Darwin collected over 400 bird specimens during his travels on the Beagle, and it was many years after his return to England that his bird collections from the Galapagos inspired (in part) his theory of evolution through natural selection. The Paris museum had 463 bird specimens in 1793 and this grew to 3411 in 1809; The Berlin museum had 2000 specimens in 1813 growing to 13,760 around 1850. In 1753 there were 1172 bird specimens in the museum established by Sir Hans Sloane but these appear to have perished before they moved to the British Museum. Early specimens from Captain Cook's voyages as well as those described by Latham in his General Synopsis of Birds (1781–1785) were also lost possibly due to poor preservation technique. The scale of collections grew to the point where they needed more space and full-time curators. In the earliest days of ornithology, collecting was the dominant method of bird observation and study. This approach has diminished with the growth of the discipline. The use of mist-netting and photography, blood sampling (for DNA, immunological and other studies), the development of optics and the use of other new techniques for studying birds have reduced the need to collect specimens for research, yet collections continue to act as a vital shared resource for science (particularly taxonomy) and conservation. In an era of mass extinction, bird collections will evidence lost species.
