Bird collections are used for a wide variety of purposes. All biological species including those of birds are represented by a holotype, the vast majority of which are full specimens (mostly skins) and in modern times explicitly designated in the original description of the taxon. All other putative members of the species may be compared to the ...
Activities vary widely from transcribing old ship logbooks to digitize the data as part of the Old Weather project to observing and counting birds at home or in the field for eBird. [1] [2] Participation can be as simple as playing a computer game for a project called Eyewire that may help scientists learn more about retinal neurons. [3]
A significant portion of the audiovisual content available in Birds of the World is collected through citizen science data collection as provided by eBird, [3] but content is also included from the Macaulay Library, as it was gathered in the Internet Bird Collection by Josep del Hoyo, the initial founder of Lynx Edicions, and his colleagues in ...
These projects help to identify distributions of birds, their population densities and changes over time, arrival and departure dates of migration, breeding seasonality, and even population genetics. [105] The results of many of these projects are published as bird atlases. Studies of migration using bird ringing or colour marking often involve ...
As the bird stem group evolved, distinctive bird features such as feathers and hollow bones appeared. Finally, at the base of the crown group, all traits common to extant birds were present. Under the widely used total-group perspective, [ 17 ] the Crocodylomorpha would become synonymous with the Crocodilia, and the Avemetatarsalia would become ...
A scientific collection is a collection of items that are preserved, catalogued, and managed for the purpose of scientific study. [ 1 ] Scientific collections dealing specifically with organisms plants , fungi , animals , insects and their remains, may also be called natural history collections or biological collections . [ 2 ]
In this list of birds by common name 11,278 extant and recently extinct (since 1500) bird species are recognised. [1] Species marked with a "†" are extinct. Contents
This WikiProject aims to help organise our rapidly growing collection of articles about birds. Included in its scope are articles for all known species, genera, families, and orders of birds (both extant and extinct ), as well as articles relating to bird anatomy, physiology, evolution, behaviours, diseases and parasites.
