'''''Calonectris''''' is a genus of [[seabird]]s. The [[genus]] name comes from [[Ancient Greek]] ''kalos'', "good" and ''nectris'', "swimmer".

The genus comprises four large [[shearwater]]s. There are two other shearwater genera, ''[[Puffinus]]'', which comprises 21 small to medium-sized shearwaters, and ''[[Ardenna]]'' with 7 larger species.<ref name=ioc>{{cite web| editor1-last=Gill | editor1-first=Frank | editor1-link=Frank Gill (ornithologist) | editor2-last=Donsker | editor2-first=David | editor3-last=Rasmussen | editor3-first=Pamela | editor3-link=Pamela Rasmussen | date=July 2021 | title=Petrels, albatrosses | work=IOC World Bird List Version 11.2 | url=https://www.worldbirdnames.org/bow/petrels/ | publisher=International Ornithologists' Union | access-date=2 January 2022 }}</ref><ref name=Penhallurick>{{cite journal | last1=Penhallurick | first1=John | last2=Wink | first2=Michael | year=2004 | title=Analysis of the taxonomy and nomenclature of the Procellariformes based on complete nucleotide sequences of the mitochondrial cytochrome ''b'' gene | journal=Emu |volume= 104 | issue=2 | pages= 125–147 | doi=10.1071/MU01060| bibcode=2004EmuAO.104..125P | s2cid=83202756 }}</ref><ref name="Estandia et al. 2021">{{cite journal |last1=Estandia |first1=A |last2=Chesser |first2=RT |last3=James |first3=HF |last4=Levy |first4=MA |last5=Ferrer Obiol |first5=J |last6=Bretagnolle |first6=V |last7=Gonzales-Solis |first7=J |last8=Welch |first8=AJ |title=Substitution rate variation in a robust procellariiform seabird phylogeny is not solely explained by body mass, flight efficiency, population size or life history traits |journal=bioRxiv |date=July 2021 |doi=10.1101/2021.07.27.453752|s2cid=236502443 |url=https://www.biorxiv.org/content/biorxiv/early/2021/07/27/2021.07.27.453752.full.pdf }}</ref>

The [[species]] in this group are long-winged birds, dark brown or grey-brown above, and mainly white below. They are pelagic outside the breeding season. They are most common in temperate and cold waters. Like most other [[Procellariiformes|tubenose]] birds, they use a shearing flight technique to move across wave fronts with the minimum of active flight, but fly with a more relaxed, fluid, flexible wing action than the other shearwaters in ''Puffinus'' and ''Ardenna''.<ref name=Collins>[[Lars Svensson (ornithologist)|Svensson, L.]], [[Killian Mullarney|Mullarney, K.]], & [[Dan Zetterström|Zetterström, D.]] (2022) ''[[Collins Bird Guide]]'', ed. 3. {{ISBN|978-0-00-854746-2}}, pages 68-69</ref>

''Calonectris'' shearwaters are long-distance [[bird migration|migrants]]. The streaked shearwater disperses from its east [[Asia]]n breeding islands throughout the western [[Pacific]] and into the eastern [[Indian Ocean]]. They come to islands and coastal cliffs only to breed. They are nocturnal at the colonial breeding sites, preferring moonless nights to minimise predation. They nest in [[Burrow nest|burrows]] and often give eerie contact [[bird vocalization|calls]] on their night time visits. They lay a single white [[bird egg|egg]]. They feed on fish, squid and similar oceanic food. They will follow fishing boats to take scraps.
