Distributional studies are fundamental in under‑standing the processes that shape species’ ranges. Suchstudies,especially those focusedonrangeshifts,arebe‑comingincreasinglyprevalentandimportantinaworldshaped by climate change and anthropogenic habitatmodifications (Parmesan et al. 2005, Lomolino et al.2006,Frey2009).

Anextralimitaldistributionrecordisthedocumen‑tationofaspeciesoutsideoftheaccumulatedscatteroflocalityrecordsortheinferredrangeborder(Frey2009).Discerning what constitutes an extralimital record de‑pendsontheperceptionofaspecies’rangemargin–thetransitionzonebetweenwhereaspeciesoccursanddoesnotoccur(Frey2009).Thistaskiscomplicatedbytheab‑stractessenceoftheconceptofrangelimit,afactrelatedto the complex anddynamicnatureof a species’ rangemargin(Lomolinoet al.2006,Frey2009).Bydefinition,atarangeedge,aspeciesisencounteringtheboundaryofitsrealizedniche(Kandaet al.2009).Therefore,aspecies’

abundance is expected todecrease andbecome increas‑inglypatchyalongtheperipheryofitsrange(Lomolinoet al.2006),minimizingthechancesofencounterbyanobserver.Workingwithsmallmammals,Frey(2009)re‑latedextralimitalrecordstoeither1) anenlargementofaspeciesrangethroughdispersalandthentheestablish‑mentofnewpopulations(= rangeexpansion)or2) thediscovery of previously undocumented populations(= rangeextension).

Inhighlymobile organisms likebirds, extralimitalrecords are sometimes located well outside the knownrange of a species. This situation, termed vagrancy, ismorecommoninmigratoryspecies(Alerstam1990,Ber‑thold 1993, Gilroy and Lees 2003, Pfeifer et al. 2007,LeesandGilroy2004,2009).

Aseriesofmechanismshavebeenproposed toex‑plain vagrancy in birds. In general terms, these can begrouped in three categories: 1) demographic dispersal(sensuLomolinoet al.2006),whichincludespopulation

growth and expansion (Veit 2000,Thorup 1998, Leesand Gilroy 2009), dismigration, natal dispersion andspacing(Berthold1993);2) pursueofresourcesthatareunpredictableinspaceand/ortime(Berthold1993,LeesandGilroy2009); and3) disorientation,which canberelatedtoexogenousfactorssuchasmagneticanomalies,storms and winds (Baker and Catley 1987, Patten andMarantz1996,Thorup1998,GilroyandLees2003,LeesandGilroy2004,2009,McLarenet al.2006,Pfeiferet al.2007),orendogenousfactorslikegeneticorphysiologicalabnormalities (Rabøl 1969, Patten and Marantz 1996,Thorup1998,GilroyandLees2003,Pfeiferet al.2007).

Vagrancyeventscompriseagradientofhyperdisperalinmigratorybirds,withextremevagrantsrepresentingthefar endof this continuum(A.C.Lees in litt.2010).AsstatedbyHengeveld(1989)andVeit(2000),“vagrantsaresimplytheindividualsthatmakeupthelongtailsoflep‑tokurticfrequencydistributionstypicalofdataondistancesmovedbyanimals”.Despitethefactthatstraybirdsusuallyperishinunfamiliarhabitat,vagrantsoccasionallyconsti‑tutepropagulesforrangeexpansion(Veit2000,GilroyandLees2003,Lomolinoet al.2006,Pfeiferet al.2007).

Vagrancyrecordsmay,however,alsobeattributedtothe encounter of previously unknown migratory popula‑tions. Gilroy and Lees (2003) coined the term “pseudo‑vagrant”for“nominally”extralimitalindividualsthatmightactuallybeusingpreviouslyunknownmigrationroutestounknown wintering grounds albeit at very low densities.SuchtermisanalogoustorangeextensionsensuFrey(2009).

Distinguishing range expansions from extensionsiscrucial inordertocorrectlydetermineaspecies’geo‑graphic distribution and interpret range shifts. Frey(2009)advocatedtheuseofbackgrounddata–recordsofspeciesotherthanthetaxonofinterestthatarelikelytobedocumentedusing the same samplingmethods–asamethodtodetermineifanextralimitalrecordreferstorangeexpansionorextension.Inmigratoryorganisms,ananalysisofthespecies’knowndistributionoutsidethebreeding season should also be conducted in order tointerpretifnewextralimitalrecordsaremostparsimoni‑ouslyattributabletovagrancyorpseudo‑vagrancy.

The occurrence of the Azure Gallinule is seasonalinsomeSouthAmericanregions,anditsmovementsareprobablytimedtocoincidewithwetorhigh‑watersea‑sons(RemsenandParker1990).MostrecordsfromPeru,Bolivia,Paraguay,mid‑westernBrazilandpossiblynorth‑easternArgentinaarerestrictedtotheaustralspringandsummer(RemsenandParker1990).Thespeciesiscur‑rentlyconsideredabreeding“northern”australmigrantinParaguay,presentfromOctobertoMay(GuyraParaguay2005),andapartialaustralmigrantinArgentina(BarnettandPearman2001),recordedthroughouttheyearwithslightpredominanceinspringandsummer(Olrog1979,Contreraset al.1990,LópezLanús1997,Chebez1999,2009,BlancoandCarbonell2001,Fraga2001,DiGia‑como2005, J.C.Chebez in litt.2009).Dated recordsfor localities in southern and southeastern Brazil otherthan the above mentioned Rio Grande do Sul recordsrefer toApril andSeptember inMinasGerais (Remsenand Parker 1990), January in western São Paulo (Wil‑lisandOniki1993),OctoberandNovemberineasternParaná(Bornschein2001),SeptemberandOctoberand/or March in northern Paraná (Anjos and Schuchmann1997)andOctoberon theParaná‑MatoGrossodoSulborder(Gimeneset al.2007,E.V.Lopesin litt.2009).Winter and autumn records from Paraguay, ArgentinaandneighboringregionsofBrazilmayrefertoearlyar‑rivals,as suggestedbyHayeset al. (1994),or topartialmigration, a more plausible hypothesis in light of thecomplexmovementsundertakenbywaterbirds inhabit‑ingwetlandsalong themidParanáand lowerParaguayRivers(seeAntas1994).

RemsenandParker(1990)emphasizedthepropen‑sityofmanyrails,crakesandgallinulesforvagrancyandtheiramazingcapabilityforextremelong‑distancedisper‑salevents.TheseauthorsalsostatedthattheAzureGal‑linuleisvagrancy‑pronefromAugustthroughDecemberand in January and February. Considering 1) that thisspecies was not recorded during intensive bird surveysconductedinthewetlandsandricepaddiesofRioGrandedoSul (Nascimento1995,Mähler Jr. et al.1996,DiasandMaurício1998,DiasandBurger2005,AccordiandBarcellos 2006,Accordi andHartz2006,Bencke et al.2007);2) thatothersecretiverailssuchastheRufous‑sid‑edCrake(Laterallus melanophaius),Red‑and‑whiteCrake(Laterallus leucopyrrhus),Dot‑wingedCrake(Porzana spi-loptera),Ash‑throatedCrake(Porzana albicollis),SpottedRail(Pardirallus maculatus),PlumbeousRail(Pardirallus sanguinolentus)andespecially thePurpleGallinulewererecordedinthese inventories;3) thatbothstaterecordsfallwithinperiodsinwhichextralimitaloccurrencesareexpected;and4) thatIberámarshes–thenearest local‑itywherethespecies isregular(seeFraga2001)– is lo‑cated c. 570 kmnorthwestofPelotas andRioGrande;weconcludethatrecordsofAzureGallinules intheex‑tremesouthofBrazillikelyrefertovagrancyratherthanpseudo‑vagrancy. Furthermore, the circumstances inwhich the Pelotas specimen was found suggests that itwasprobablyflyingatnightandattractedbycitylights,aphenomenoncommonlyrecordedinmigratingrailsandgallinules. If properly confirmed, an overlooked recordfromUruguay,basedonanobservationmadeinJanuaryor February 1992 at an unknown locality (Blanco andCanevari1992),mayalsorelatetoavagrant.Theseva‑grantindividualsareprobablyovershooters(sensuGilroyand Lees 2003) – birds that fly beyond their intendeddestination,perhapsassistedbyfavorabletail‑winds,andturnupinareaswellbeyondtheirnormalrange.DuetotheirrelativeproximitywithRioGrandedoSul,wetlandsalong the Paraná and Paraguay rivers in Argentina andParaguayaretheprobablesourceofindividualsrecordedin the state.On theotherhand, if the species is genu‑inelyoverlookedinRioGrandedoSul,localpopulationsof this tropicalgallinulewouldmost likelybe found inpoorlysurveyedmarshesandricepaddies in thenorth‑western sector of the State, especially along the borderwithArgentinanearIberámarshes.
