Editing Calonectris (section)

==Taxonomy==
The genus ''Calonectris'' was introduced in 1915 by the ornithologists [[Gregory Mathews]] and [[Tom Iredale]] with the [[streaked shearwater]] as the [[type species]].<ref>{{ cite journal | last1=Mathews | first1=Gregory M. | author1-link=Gregory Mathews | last2=Iredale | first2=Tom | author2-link=Tom Iredale | year=1915 | title=On some petrels from the North-East Pacific Ocean  | journal=Ibis | volume=57 | issue=3 | pages=572–609 [590, 592] | doi=10.1111/j.1474-919X.1915.tb08206.x | url=https://www.biodiversitylibrary.org/page/8750380 }}</ref> The genus name combines the [[Ancient Greek]] ''kalos'' meaning "good" or "noble" with the genus name ''Nectris'' that was used for shearwaters by the German naturalist [[Heinrich Kuhl]] in 1820. The name ''Nectris'' comes from the Ancient Greek ''nēktris'' meaning "swimmer".<ref>{{cite book | last=Jobling | first=James A. | year=2010| title=The Helm Dictionary of Scientific Bird Names | publisher=Christopher Helm | location=London | isbn=978-1-4081-2501-4 | pages=[https://archive.org/stream/Helm_Dictionary_of_Scientific_Bird_Names_by_James_A._Jobling#page/n86/mode/1up 86], [https://archive.org/stream/Helm_Dictionary_of_Scientific_Bird_Names_by_James_A._Jobling#page/n267/mode/1up 267] }}</ref><ref>{{ cite book | last=Kuhl | first=Heinrich | author-link=Heinrich Kuhl | date=1820 | title=Beiträge zur Zoologie und vergleichenden Anatomie  | language=German, Latin | location=Frankfurt am Main | publisher=Verlag der Hermannschen Buchhandlung | page=148 | url=https://www.biodiversitylibrary.org/page/28230944 }}</ref>

Scopoli's shearwater and Cory's shearwater were previously considered as conspecific and formed the Cory's shearwater complex (''Calonectris diomedea''). Based on the lack of hybridization and differences in mitochondrial DNA, morphology and vocalisation, the complex was split into two separate species. The English name "Cory's shearwater" was transferred to ''Calonectris borealis'' while what was previously the [[nominate subspecies]] became Scopoli's shearwater (''Calonectris diomedea'').<ref>{{ cite journal | last1=Sangster | first1=G. | last2=Collinson | first2=J.M. | last3=Crochet | first3=P.-A. | last4=Knox | first4=A.G. | last5=Parkin | first5=D.T. | last6=Votier | first6=S.C. | author1-link=George Sangster | year=2012 | title=Taxonomic recommendations for Western Palearctic birds: eighth report | journal=Ibis | volume=154 | issue=4 | pages=874–883 | doi=10.1111/j.1474-919X.2012.01273.x | doi-access=free}}</ref><ref name=ioc/>

Extinct species, ''[[Calonectris krantzi]]'' from the [[Early Pliocene]] and ''[[Calonectris wingatei]]'' from the [[Middle Pleistocene]], have also been described from [[fossil]]s. ''Calonectris kurodai'', another fossil from the Middle Miocene Calvert Formation of Chesapeake Bay is named after the Japanese ornithologist [[Nagahisa Kuroda]].<ref>{{cite journal|doi=10.2988/09-19.1 |title=A new diminutive species of shearwater of the genus Calonectris (Aves: Procellariidae) from the Middle Miocene Calvert Formation of Chesapeake Bay |journal=Proceedings of the Biological Society of Washington |volume=122 |issue=4 |pages=466–470 |year=2009 |last1=Olson |first1=Storrs L. |s2cid=86663993 }}</ref>
