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 ...
The new tools of molecular biology changed the study of bird systematics, which changed from being based on phenotype to the underlying genotype. The use of techniques such as DNA–DNA hybridization to study evolutionary relationships was pioneered by Charles Sibley and Jon Edward Ahlquist, resulting in what is called the Sibley–Ahlquist ...
[7] [8] Lack based his analysis on the large collection of museum specimens collected by the 1905–06 Galápagos expedition of the California Academy of Sciences, to whom Lack dedicated his 1947 book. The birds vary in size from 10 to 20 cm (4 to 8 in) and weigh between 8 and 38 grams (0.3 and 1.3 oz).
For example, if we consider the crown-birds (i.e. all extant birds and the rest of the family tree back to their most recent common ancestor), extinct side branches like the dodo or great auk are still descended from the most recent common ancestor of all living birds, so fall within the bird crown group.

John Gould FRS (/ ɡ uː l d /; 14 September 1804 – 3 February 1881 [1]) was an English ornithologist who published monographs on birds, illustrated by plates produced by his wife, Elizabeth Gould, and several other artists, including Edward Lear, Henry Constantine Richter, Joseph Wolf and William Matthew Hart.
Numerous books, and at one point a journal, have been published on egg collecting and identification: [2] Thomas Mayo Brewer, (1814–80), an American ornithologist, wrote most of the biographical sketches in the History of North American Birds, by Baird, Brewer, and Ridgway (1874–84). He has been called "the father of American oölogy".
James Bond (January 4, 1900 – February 14, 1989) was an American ornithologist and expert on the birds of the Caribbean, having written the definitive book on the subject: Birds of the West Indies, first published in 1936. He served as a curator of the Academy of Natural Sciences of Philadelphia.
Many kinds of birds are known to congregate in groups of varying size; a congregation of nesting birds is called a breeding colony. Colonial nesting birds include seabirds such as auks and albatrosses ; wetland species such as herons ; and a few passerines such as weaverbirds , certain blackbirds , and some swallows .
