[[File:European Storm Petrel From The Crossley ID Guide Eastern Birds.jpg|thumb|Composite from The Crossley ID Guide]]
The '''European storm petrel''' ('''''Hydrobates pelagicus'''''), also known as '''British storm petrel''', or just '''storm petrel''', is a species of [[seabird]] in the [[northern storm petrel]] [[family (biology)|family]], Hydrobatidae. The small, square-tailed bird is entirely black except for a broad, white rump and a white band on the under wings, and it has a fluttering, bat-like flight. The large majority of the population breeds on islands off the northern coasts of Europe, with the greatest numbers in the [[Faroe Islands]], United Kingdom, Ireland, and Iceland. The Mediterranean population is a separate subspecies whose strongholds are [[Filfla]] Island (Malta), [[Sicily]], and the [[Balearic Islands]]. This subspecies is indiscernible at sea from its Atlantic relatives.

The storm petrel nests in crevices and burrows, sometimes shared with other seabirds or rabbits, and lays a single white egg, usually on bare soil. The adults share the lengthy [[egg incubation|incubation]] and both feed the chick, which is not normally brooded after the first week. This bird is strongly [[bird migration|migratory]], spending the [[Northern Hemisphere]] winter mainly off the coasts of South Africa and Namibia, with some birds stopping in the seas adjoining West Africa, and a few remaining near their Mediterranean breeding islands. This petrel is strictly oceanic outside the breeding season. It feeds on small fish, squid, and [[zooplankton]], while pattering on the sea's surface, and can find oily, edible items by smell. The food is converted in the bird's stomach to an oily orange liquid, which is regurgitated when the chick is fed. Although usually silent at sea, the storm petrel has a chattering call given by both members of a pair in their courtship flight. The male has a purring song given from the breeding chamber.

The storm petrel cannot survive on islands where land mammals such as rats and cats have been introduced, and it suffers natural predation from [[gull]]s, [[skua]]s, [[owl]]s, and [[falcon]]s. Although the population may be declining slightly, this petrel is classified by the [[International Union for Conservation of Nature]] as being of [[least concern]] due to its high total numbers. Its presence in rough weather at sea has led to various mariners' superstitions, and by analogy, to its use as a symbol by revolutionary and [[anarchy|anarchist]] groups.

== Taxonomy ==

The [[Northern storm petrel|northern storm petrels]], Hydrobatidae, are one of the four [[family (biology)|families]] of the [[Procellariiformes]] or "tubenoses", an [[order (biology)|order]] of [[seabird]]s that also includes the albatrosses in the family [[Diomedeidae]], the petrels and shearwater in the family [[Procellariidae]] and the southern storm petrels in the family [[Oceanitidae]].<ref name=ioc/> The northern storm petrels are more closely related to members of the family Procellariidae than they are to the southern storm petrels.<ref>{{ cite journal | last1=Prum | first1=R.O. | author1-link=Richard Prum | last2=Berv | first2=J.S. | last3=Dornburg | first3=A. | last4=Field | first4=D.J. | last5=Townsend | first5=J.P. | last6=Lemmon | first6=E.M. | last7=Lemmon | first7=A.R. | year=2015 | title=A comprehensive phylogeny of birds (Aves) using targeted next-generation DNA sequencing | journal=Nature | volume=526 | issue=7574 | pages=569–573 | doi=10.1038/nature15697 | pmid=26444237 | doi-access=free | bibcode=2015Natur.526..569P }}</ref> The European storm petrel was formerly defined as the only member of the genus ''Hydrobates'', the remainder of the Hydrobatinae being placed in ''[[Oceanodroma]]'', although the [[least storm petrel]] was sometimes separated as the sole member of ''Halocyptena''.<ref name=hbwfam/> Molecular phylogenetic studies found that ''Oceanodroma'' was [[paraphyletic]] with respect to ''Hydrobates''. As a consequence, in 2021 all members of ''Oceanodroma'' were subsumed into an enlarged ''Hydrobates''.<ref name=ioc/><ref>{{cite journal | last1=Chesser | first1=R.T.  | last2=Burns | first2=K.J. | last3=Cicero | first3=C. | last4=Dunn | first4=J.L. | last5=Kratter | first5=A.W | last6=Lovette | first6=I.J. | last7=Rasmussen | first7=P.C. | last8=Remsen | first8=J.V.

The storm petrel was first described by [[Carl Linnaeus]] in his landmark 1758 [[10th edition of Systema Naturae|10th edition of ''Systema Naturae'']] as ''Procellaria pelagica''.<ref name=Linn/> It was moved to the genus ''Hydrobates'' by [[Friedrich Boie]] in 1822.<ref name=Ernst1979/><ref name=Boie1822/> "Petrel", first recorded in 1602, is a corruption of ''pitteral'', referring to the bird's pitter-pattering across the water. The suggestion that the word refers to [[Saint Peter|St Peter]]'s walking on the waves is a later invention. "Storm" arises from seamen's association of this bird with bad weather.<ref name=lockwood115/> In English, the name of the species was written as "storm'''y''' petrel" by some 19th-century authors.<ref name=eg/>

The [[binomial nomenclature|scientific name]] ''hydrobates'' derives from [[Greek language|Greek]] "[[wikt:hydro-|hydro-]]", from ''hydōr'' "water", and ''batēs'' "walker",<ref>{{LSJ|u(/dwr|ὕδωρ}}, {{LSJ|ba%2Fths|βάτης|ref}}.</ref><ref>{{OEtymD|hydro-}}</ref> and ''pelagicus'' from ''pelagikos'' "pelagic, of the (open) sea", from ''pelagos'' "sea, open sea, high sea".<ref name=job393/><ref name=job404/><ref>{{LSJ|pe/lagos|πέλαγος|shortref}}.</ref> There are two recognised [[subspecies]], the North Atlantic [[Subspecies#Nominotypical subspecies and subspecies autonyms|nominate subspecies]], ''H. p. pelagicus'' (Linnaeus, 1758), and the [[Mediterranean Sea|Mediterranean]] ''H. p. melitensis'' ([[Antonio Schembri (ornithologist)|Schembri]], 1843).<ref name=ioc/> Although there is some [[gene]]tic support for classifying the southern form as a separate species,<ref name=gagnon/> the [[Morphology (biology)|morphology]] is not considered sufficiently different from that of the nominate subspecies to justify a split.<ref name=hbwfam/>

== Description ==

[[File:Hydrobates pelagicus.jpg|thumb|Storm petrels cannot walk on land; they shuffle on their [[tarsus (skeleton)|tarsi]].]]
[[File:Oceanite.tempete.jogo.jpg|thumb|Old illustrations, such as this one by [[John Gould]], were painted from skins, and showed petrels in improbable standing positions.<ref name=Coward/>]]

The storm petrel is a small bird, {{convert|14|–|18|cm|in|abbr=on}} in length with a {{convert|36|–|39|cm|adj=on|in|abbr=on}} wingspan.<ref name=BWP/> It weighs {{convert|20|–|38|g|oz|abbr=on}}, with an average of {{convert|28|g|oz|abbr=on}}.<ref name=debize/> It is square-tailed and has all-black [[plumage]] except for a snow-white rump that extends to the sides of the tail base and a broad white band on the under wings. Juveniles in fresh plumage can also show a narrow white bar on the upper wing. The plumage becomes dark brown rather than black as it becomes worn.<ref name=Mullarney/> No obvious differences between the sexes are seen, although in the Mediterranean subspecies, at least, most captured birds can be sexed using a formula which involves multiplying the wing length by the length of the white rump band; females are slightly larger and have a longer white rump than males.<ref name=baraja/> The Mediterranean subspecies has longer wings and a heavier bill on average than the nominate form, but neither sex nor subspecies can be determined by observation at sea.<ref name=vand/>

[[moulting|Moult]] is prolonged in all tubenoses, since they must maintain an ability to fly. Northern populations start replacing their plumage after those further south, reflecting the later start to their breeding season. Birds in a Welsh colony commenced moulting in early August, while populations in northern Spain and the Balearics started in early July and mid-June, respectively. Breeding birds moult later than non-breeders.<ref name=moult/>

The storm petrel's large nasal [[olfactory bulb]]s facilitate a keen sense of smell (unlike most birds),<ref name=Enticott196/> and the birds have a distinctive musty aroma which can help researchers locate breeding colonies.<ref name=bblamp/> Individual petrels recognise their own body scent and can use it to locate their nests in the dark.<ref name=deleon/>

Their flight is weak-looking and resembles that of a bat, with fluttering interspersed with short glides. When feeding, the birds hang with raised wings and patter on the surface with their feet, but unlike [[Wilson's storm petrel]], do not look as if they are walking on the water. Birds sometimes settle on the sea.<ref name=BWP/> Like other petrels, the European storm petrel cannot walk properly on land, but shuffles on its [[tarsus (skeleton)|tarsi]];<ref name=Soper/> once there is enough room, the bird flaps its wings to support itself on its toes.<ref name=hume110/>

The European storm petrel can be distinguished from related [[Western Palaearctic]] species by the white bar on its under wing and its distinctive fluttering flight. Compared to [[Leach's storm petrel]], [[band-rumped storm petrel]], and the recently described [[Monteiro's storm petrel]], it is also smaller, darker, and shorter-winged, and has a square tail. Wilson's storm petrel lacks an under wing bar, and has long legs with the feet visible beyond the tail.<ref name=BWP/>

=== Voice ===

In its display flight, the storm petrel gives a call consisting of eight or more repetitions of a fast ''ter-CHICK'' sounds ending in a [[trill (music)|trill]] (rapid alternation of notes). This chattering, staccato call is highly variable in pitch, stress, and length.<ref name=BWP/><ref name=debize/> Both sexes make the call, which is used as an advertisement for a mate, for pair recognition, and in the nuptial flight. The details of the vocalisation vary geographically, including between the Atlantic and Mediterranean populations, and birds recognise calls from their own breeding area.<ref name=BWP/><ref name=bretagnolle/> The chatter-call of the Mediterranean subspecies is distinctive. It has the first two notes running into each other, and the final element is sometimes doubled.<ref name=vand/> The storm petrel is usually silent at sea, but sometimes gives the chattering call.<ref name=BWP/> A purring song ''arrr-r-r-r-r-r-r''{{nbs}}... ending with a sharp ''chikka'' is given in the burrow only by the male;<ref name=debize/><ref name=bretagnolle/> it was described by [[Charles Oldham (naturalist)|Charles Oldham]] as "like a fairy being sick".<ref name=bbDavis1/> Other vocalisations include a fast ''wick-wick-wick'', sometimes given in flight, and an ''up-CHERRK'' alarm which resembles the chatter-call.<ref name=BWP/> Chicks give a whistling ''pee-pee-pee'' call when being fed, and a faster version of this vocalisation is used by adults and young to signal distress.<ref name=Cramp/>

== Distribution and habitat ==

[[File:"Ringing" a Storm Petrel by Cape Wrath - geograph.org.uk - 753403.jpg|thumb|[[Bird ringing|Ringing]] at [[Cape Wrath]]]]

Storm petrels breed only in the Western Palaearctic on islands off the Atlantic and Mediterranean coasts of Europe.<ref name=BWP/> The largest colonies are in the [[Faroe Islands]] (150,000–400,000 pairs), United Kingdom (20,000–150,000), Ireland (50,000–100,000), and Iceland (50,000–100,000), with smaller breeding areas off Norway, Malta, Spain, the [[Canary Islands]], Italy, France, and Greece.<ref name="iucn status 12 November 2021" /> The strongholds of the ''H. p. melitensis'' subspecies are the islands of [[Filfla]] (Malta), [[Sicily]], and the [[Balearic Islands]], with smaller sites elsewhere in the Mediterranean. This latter form also breeds in North Africa; definitely in Tunisia, probably in Algeria and possibly in Morocco.<ref name=debize/> Because of its nocturnal habits and the problems of accessing some of the small islands on which it breeds, the distribution is poorly known. A colony was discovered as recently as 2009, on [[Lampedusa]].<ref name=bblamp/> The storm petrel has been recorded as a vagrant in several European countries as far east as Ukraine, in the [[Guinea (region)|Guinea region]] of West Africa, and in Turkey, Israel, Lebanon,<ref name="iucn status 12 November 2021" /> and the US.<ref name=mcneil/> Although no North American records were reported for more than 30 years after the first in 1970, this bird has been more or less annual in small numbers since 2003.<ref name=howell/>

The storm petrel breeds on exposed and usually uninhabited islands, which it visits only at night. It otherwise frequents mid-depth waters away from the coastal zone, but not over the ocean deeps. In the breeding season, it is mainly found between the 10–25{{nbs}}°C July [[Isotherm (contour line)|isotherms]].<ref name=BWP/> In Europe, it is rarely seen from land except in autumn storms.<ref name=Blomdahl/>

The storm petrel is [[bird migration|migratory]], spending the Northern Hemisphere winter mainly in cool waters off the coasts of South Africa and Namibia, south to [[latitude]] 38°S and east to [[KwaZulu-Natal]].<ref name=BWP/><ref name=SASOL/> Some birds stay north of the equator in the seas adjoining Mauritania and [[Río de Oro|Rio de Oro]], and a few remain near the breeding islands, especially in the Mediterranean. It is strictly oceanic outside the breeding season,<ref name=BWP/><ref name=hbwonlinehydrobates/> although it is described as regularly seen from land in West Africa.<ref name=Barlow/> Young birds do not return to the breeding colonies until their second or third year. Birds mostly head south from the breeding islands between September and November, reaching West Africa by mid-November and the south Atlantic by the end of the year. The return passage starts in April, with late records from the tropics and further south probably representing subadult birds that will not breed that year.<ref name=BWP/>

== Behaviour ==
=== Breeding ===

The storm petrel is sexually mature at age 4–5 years, with the Mediterranean subspecies typically breeding a year earlier than the Atlantic form. Breeding happens in [[colony (biology)|colonies]] and normally begins in late May or June.<ref name=bblamp/><ref name=hbwonlinehydrobates/> Pairs have a repeated nocturnal display flight in which the male chases the female, the chase being accompanied by flight calls. Some near-adult birds may pair up and occupy a hole at the same time, prior to breeding in the following year.<ref name=BWP/>

Storm petrels normally nest in crevices between or under rocks, or burrow in the soil.<ref name=BWP/> When they make their own tunnels, they loosen the earth with their bills and kick out the debris with their feet. The birds less commonly nest in walls, under buildings, or down rabbit burrows. Disused or occupied burrows of [[Atlantic puffin]]s and [[Manx shearwater]]s are sometimes used, and the petrel pair may share a common entrance with those seabirds, rabbits, or other pairs of its own species. Where other occupants are present, the petrels dig a side burrow or use an existing low-roofed tunnel which the larger birds or rabbits cannot easily enter. Even so, puffins and shearwaters sometimes access and destroy nests, and adult petrels may be killed by their larger neighbours.<ref name=bbDavis1/> Human-made plastic nesting tubes are readily used, and may provide protection against predators.<ref name=debize/><ref name=bolton/> Birds usually mate for life and use the same hole every year.<ref name=bbDavis1/>

The nest tunnel is {{convert|10|–|300|cm|in|abbr=on}} long and {{convert|5|–|8|cm|in|abbr=on}} across, with a slightly narrower entrance. The nest chamber is typically unlined, although pairs may bring in some grass, [[bracken]], or seaweed. Although the storm petrel is generally not territorial when breeding, a pair defends the nest chamber itself after the eggs have been laid.<ref name=BWP/>

The [[clutch (eggs)|clutch]] is a single egg, usually pure white, sometimes with some reddish-brown spots that soon disappear.<ref name=BWP/> The average size of the egg is {{convert|28|x|21|mm|in|abbr=on}}, and it weighs {{convert|6.8|g|oz|abbr=on}}, of which 6% is shell.<ref name=bto/> If an egg is lost early enough, a replacement may be laid on rare occasions. This is very unusual for tubenoses.<ref name=ming/> The eggs are [[egg incubation|incubated]] by both parents for 38–50{{nbs}}days, the longer periods arising when the eggs have become chilled through adult absence.<ref name=BWP/> One adult typically spends three days at a time on the egg while its partner feeds at sea.<ref name=bbDavis1/> The chicks are [[altricial]] and covered with silver-grey down, and are fed by both parents with their regurgitated oily stomach contents.<ref name=Coward/><ref name=hbwonlinehydrobates/><ref name=bto/> The adults do not normally stay with the chick after the first week, visiting only to bring food.<ref name=bbDavis2/> After about 50{{nbs}}days, the chicks are fed less regularly, sometimes with gaps of several days, and the parents may stop visiting completely shortly before the chick leaves the nest.<ref name=bbDavis2/> The chicks [[fledge]] about 56–86{{nbs}}days after hatching,<ref name=BWP/> and receive no parental support after leaving the nest hole.<ref name=hume94/>

Tubenoses have smaller egg clutches and much longer and more variable incubation and fledging times than [[passerine]]s with similarly sized eggs, resembling [[Swift (bird)|swift]]s in these developmental factors. Tubenoses and swifts have generally secure nest sites, but their food sources are unreliable, whereas passerines are vulnerable in the nest but food is usually plentiful.<ref name=lacklack/><ref name=Boersma/> In the particular case of the storm petrel, it has a body temperature perhaps 3{{nbs}}°C lower than other small birds, and this may also contribute to the lengthy incubation.<ref name=hume94/>

The adult petrel's annual death rate is 12–13%,<ref name=hbwonlinehydrobates/> and the typical life span is 11{{nbs}}years. Longevity records established from [[bird ringing]] recoveries include a bird aged 31{{nbs}}years{{nbs}}11 months{{nbs}}9 days,<ref name=bto/> and another aged more than 33{{nbs}}years.<ref name=euring/>

=== Feeding ===

[[File:Velella Bae an Anaon.jpg|thumb|upright|The [[Velella|by-the-wind sailor]] is a small [[jellyfish]] eaten by storm petrels.<ref name=Elbee/>]]

The storm petrel normally flies within {{convert|10|m|ft|abbr=on}} of the water surface and typically feeds by picking items off the sea as it patters over the surface.<ref name=BWP/> Birds have been observed diving for food to a depth of not more than {{convert|0.5|m|in|abbr=on}}.<ref name=bblflood/><ref name=griffiths/> and it is claimed, using indirect measurements, that the Mediterranean subspecies reaches depths of up to {{convert|5|m|ft|abbr=on}}).<ref name=albores/> A bird may range up to {{convert|200|km|mi|abbr=on}} over the course of two or three days in search of food.<ref name=parkin/> Although the bird usually feeds during the day, in the breeding season petrels will often feed at night close to the shore.<ref name=Elbee/><ref name=poot/>

The typical prey consists of surface organisms such as small fish, [[squid]], [[crustacean]]s and [[jellyfish]]. The storm petrel will also eat offal and oily food, often located by smell, and will follow ships.<ref name=BWP/><ref name=humerspb/> In the Atlantic, more than half the food items are [[zooplankton]] and the fish caught include small [[Atlantic herring|herring]] and [[European sprat|sprats]]; whale carcasses are scavenged where available. During digestion, the plankton is quickly converted to an oily orange liquid that owes its colour to [[carotenoid]]s. Larger prey items take longer to digest.<ref name=Elbee/> The oil, rich in [[vitamin A]], is produced by a large gland in the stomach.<ref name=Karleskint/> The Mediterranean subspecies' diet is mainly fish, particularly [[Gymnammodytes cicerelus|Mediterranean sand eels]]. Petrels also catch [[mysida|opossum shrimps]] from waters close to the colony.<ref name=debize/> [[Bluefin tuna]] farms are exploited on the Maltese island of Filfla; birds from the large local colony feed on the unwashed food fed to the farmed tuna, a mixture of fish, squid and prawns which produces a sizeable oily slick.<ref name=borg/> Small numbers of insects are caught near breeding colonies, and some plant material, including [[flowering plant|angiosperm]] seeds and [[sorrel]], has been found in the stomach contents.<ref name=Coward/><ref name=Elbee/> A study on Leach's storm petrel, which consumes similar items, showed that the petrels were snipping pieces off plant leaves in flight, but it could not be confirmed that this was in the course of catching insects.<ref name=BBainslie/> Nasal glands remove excess salt from seawater consumed by the petrel as a concentrated solution excreted through the nostrils.<ref name=Karleskint/>

Petrels can be attracted to boats with "[[chumming|chum]]", a malodorous mixture typically containing fish heads, bones and offal, with added fish oil and [[popcorn]] to aid flotation. An apparently empty ocean will soon fill with hundreds of birds attracted by the smell. The attraction of the fishy odour is sometimes enhanced by the addition of [[dimethyl sulfide|dimethylsulphide]] (DMS) a chemical also naturally produced by some [[plankton]]ic organisms, although there are doubts about the safety of this possible [[carcinogen]].<ref name=bblflood/><ref name=bbfloodbw/>

== Predators and parasites ==

[[File:Eleonorenfalke1.jpg|thumb|The [[Eleanora's falcon]] is a local predator on some Mediterranean islands.]]

Adults and young are vulnerable to predation at the breeding colonies, their only defence being to spit oil.<ref name="iucn status 12 November 2021" /><ref name=Coward/> Petrels cannot breed on islands where rats have been introduced, and feral cats frequently kill these birds on [[Foula]] in the [[Shetland Islands]].<ref name=cats/> The [[American mink]], a non-native species in Europe, is a strong swimmer, and can colonise islands up to {{convert|2|km|yd|abbr=on}} from the mainland.<ref name=ratcliffe/> Natural predators of petrels and other seabirds include skuas and large gulls. The [[yellow-legged gull]] is a particular problem in the Mediterranean, and [[great skua]]s were estimated to kill 7,500 petrels a year on [[St Kilda, Scotland|St Kilda]], an unsustainable number.<ref name=debize/><ref name=parkin/> Some [[great black-backed gull]]s on the Atlantic islands specialise in taking seabird chicks at night,<ref name=bbDavis2/> and [[peregrine falcon]]s hunt adults at sea.<ref name=Soper/> Localised predators include [[Eleonora's falcon]] on the [[Columbretes Islands]] and the nocturnal [[Western barn owl|barn owl]] on the Balearics; a few owls can wipe out a colony.<ref name=debize/> The [[little owl]] is also a predator of both adults and young where it occurs.<ref name=bbDavis2/>

[[Feather mite]]s of at least two species have been found on the storm petrel, with ''[[Halipeurus pelagicus]]'' occurring at much higher densities than ''[[Philoceanus robertsi]]''.<ref name=louse/> The [[flea]] ''[[Xenopsylla gratiosa]]'' and [[Dermanyssidae|dermanyssid]] [[mite]]s are commonly found, with lower numbers of [[tick]]s. These blood-sucking parasites slow the growth rate of nestlings and may affect their survival rate.<ref name=merinoetal/>

Storm petrels seem to be largely free of [[haematozoa|blood parasites]], even when in close proximity to carrier species such as the yellow-legged gull.<ref name=merino/><ref name=quill/> It has been suggested that seabird species with long incubation periods and long lives have well-developed immune systems that prevent serious blood parasitism.<ref name=espartza/>

== Status ==

The European population of the storm petrel has been estimated at 430,000–510,000 breeding pairs or 1,290,000–1,530,000 individual birds and makes up 95% of the world total numbers.<ref name=hbwfam/> The population estimate includes 11,000 to 16,000 breeding pairs of the Mediterranean subspecies.<ref name=debize/> It is very difficult to accurately determine storm petrel populations. The main method used is listening for responses to playback calls at burrow entrances, but infra-red filming may also be an option.<ref>{{cite journal|author1=Perkins, A. J.|author2=Bingham, C. J.|author3=Bolton, M.|year=2018|title=Testing the use of infra-red video cameras to census a nocturnal burrow-nesting seabird, the European Storm Petrel ''Hydrobates pelagicus''|journal=Ibis|volume=160|pages=365–378|doi=10.1111/ibi.12539|issue=2}}</ref>

Although this species' population now appears to be declining, the decrease is not rapid or large enough to trigger conservation vulnerability criteria. Given its high numbers, this petrel is therefore classified by the [[International Union for Conservation of Nature]] as being of [[least concern]]. The perceived decline may be due increased predation from gulls, skuas and introduced mammals.<ref name="iucn status 12 November 2021" /> Eradication of rats protects seabird colonies and may enable recolonisation of islands cleared of rodents.<ref name=ratcliffe/> Predation of cave-nesting petrels in the Balearics by yellow-legged gulls is restricted to relatively few individual gulls specialising in this prey item;<ref name=oro/> this means the problems can be controlled by selective culling and the provision of plastic nest boxes.<ref name=yesou/>

Because it feeds in flight, the storm petrel is less affected by [[oil spill|oil pollution]] than other seabirds, and may be able to use its good sense of smell to avoid slicks, although a large spill near a breeding colony could have serious consequences.<ref name=hbwfam/>

== In culture ==

Its association with storms makes the storm petrel a bird of bad omen to mariners; they are said to either foretell or cause bad weather.<ref name=Albatross/> A more prosaic explanation of their appearance in rough weather is that, like most oceanic seabirds, they rely on the winds to support them in flight and just sit on the water surface when becalmed.<ref name=Fisher/> The birds were sometimes thought to be the souls of perished sailors,<ref name=Cocker/> and killing a petrel was believed to bring bad luck.<ref name=Albatross/><ref name=Cocker/> The petrel's reputation led to the old name of ''witch'',<ref name=lockwood115/> although the commonest of the folk names is [[Mother Carey]]'s chicken, a name also used for storm petrels in general in the UK and North America from at least 1767.<ref name=OED>{{Cite OED|Mother Carey}}</ref> This is believed to be a corruption of ''mater cara'' (''dear mother'', the [[Mary (mother of Jesus)|Virgin Mary]]), a reference to the supernatural Mother Carey, or a superstitious modification of an earlier ''Mother Mary's chicken'' to reduce the potency of the religious name.<ref name=Cocker/> The Mother Carey character appears a number of times in literature. In the [[C. Fox Smith|Cicely Fox Smith]] poem "Mother Carey", she calls old sailors to return to the sea,<ref name=FoxSmith/> but in [[John Masefield]]'s poem of the same name she is seen as a wrecker of ships.<ref name=Masefield/> She appears as a fairy in [[Charles Kingsley]]'s ''[[The Water-Babies, A Fairy Tale for a Land Baby|The Water Babies]]'' and is depicted in one of [[Jessie Willcox Smith]]'s illustrations for the book.<ref name=Kingsley/>

The association of the storm petrel with turbulent weather has led to its use as a metaphor for revolutionary views,<ref name=ziolkowski111/> the [[epithet]] "stormy petrel" being applied by various authors to characters as disparate as [[Roman Republic|Roman]] [[tribune]] [[Publius Clodius Pulcher]],<ref name=Frost1909/> a [[Presbyterian]] minister in the early Carolinas,<ref name=Lynah1934/> an Afghan governor,<ref name=Grey1929/> or an [[Arkansas]] politician.<ref name=Jacobson1925/>
A 1901 poem by Russian writer [[Maxim Gorky]] is invariably titled in English as "[[The Song of the Stormy Petrel]]", although that may not be a perfectly accurate translation of the Russian title "Песня о Буревестнике", because "Буревестник" (the name of the bird in Russian) translates to the English general term "storm bird".{{efn|The 1903 edition of [[Vladimir Dal]]'s ''[[Explanatory Dictionary of the Living Great Russian Language]]'', defined ''burevestnik'' (the name of the bird actually used by Gorky) or "bird of storm" as a generic name for the [[Procellariidae]], and illustrated it with several examples, including the species known in English as the [[wandering albatross]], [[southern giant petrel]], [[northern fulmar]] and the European storm petrel. The Russian name for the European storm petrel, according to the same dictionary, is ''kachurka'', rather than an [[adjective phrase]] with ''burevestnik''.<ref name=Dahl/> This is a modern reprint (using modernized Russian orthography) of the 1903 edition that would have been familiar to Gorky and his readers.}} The poem was called "the battle anthem of the revolution", and earned Gorky the nickname "The Storm Petrel of the Revolution".<ref name=miro/>

Various [[Insurrectionary anarchism|revolutionary anarchist]] groups adopted the bird's name, either as a group identifier, as in the [[Spanish Civil War]],<ref name=Christie/> or for their publications. ''The Stormy Petrel'' (''Burevestnik'') was the title of the magazine of the [[Anarchism in Russia|Anarchist Communist Federation in Russia]] around the time of the [[Revolution of 1905|1905 revolution]],<ref name=Yaroslansky/> and is still an imprint of the London group of the [[Anarchist Federation (Britain)|Anarchist Federation]].<ref name=afed/> To honour Gorky and his work, the name ''Burevestnik'' was bestowed on a variety of institutions, locations, and products in the USSR.<ref name=ziolkowski111/>

In the film ''[[Pirates of the Caribbean: Dead Man's Chest]]'', the bursar of the ''Edinburgh Trader'' (played by Max Baker) makes a reference to Mother Carey's chickens, moments before the Kraken attacks the ship.
