The Sibley–Monroe checklist is a list of bird species based on a study conducted by Charles Sibley and Burt Monroe. It drew on extensive DNA–DNA hybridization studies to reassess the relationships between modern birds. It was considered a landmark in ornithology on its release. [1]
Beyond the base coloring of a rosy-faced lovebird, there are mutations that exist independently of any other mutation. These mutations are of three distinct types: co-dominant (exemplified by the Orangefaced, Dark and Violet mutations), recessive (exemplified by the Edged Dilute mutation), and sex-linked (exemplified by Lutino, Pallid [also known as Australian Cinnamon], American Cinnamon, and ...
The black-chinned hummingbird (Archilochus alexandri) is the bird species known to have the smallest genome among birds, which is only 0.91 Gb long.The genomic evolution of birds has come under scrutiny since the advent of rapid DNA sequencing, as birds have the smallest genomes of the amniotes despite acquiring highly derived phenotypic traits.
The Union merged with the Cooper Ornithological Society in 2016 to form the American Ornithological Society. [1] The checklist was first published in 1886; [ 2 ] the seventh edition of the checklist was published in 1998 [ 3 ] and is now updated every year by an open-access article published in the Ibis .

Passerines, the "song birds". This is the largest order of birds and contains more than half of all birds. Family Acanthisittidae. Genus Acanthisitta - rifleman; Genus Xenicus - New Zealand wrens; Family Acanthizidae - scrubwrens, thornbills, and gerygones Genus Acanthiza – thornbill; Genus Acanthornis – scrubtit; Genus Aethomyias ...
An example is thermo-regulation in Sauropsida, which is the clade containing the lizards, turtles, crocodiles, and birds. Lizards, turtles, and crocodiles are ectothermic (coldblooded), while birds are endothermic (warmblooded). Being coldblooded is symplesiomorphic for lizards, turtles, and crocodiles, but they do not form a clade, as ...
The taxonomic treatment [3] (designation and sequence of orders, families and species) and nomenclature (common and scientific names) used in the accompanying bird lists adheres to the conventions of the AOS's (2019) Check-list of North American Birds, the recognized scientific authority on the taxonomy and nomenclature of North America birds.
Among them is the family Cathartidae (New World vultures) which the American Ornithological Society (AOS), the Clements taxonomy, and BirdLife International's Handbook of the Birds of the World place in its own order, Cathartiformes.
