1. INTRODUCTION1.1. AvianMonitoringPrograms

Through the spread of urbanization and the intensive agriculture needed to support arapidlygrowingpopulation,humanshaveoccupiedmanyhigh-valuehabitatsintheworld,principally estuaries, riverine valley bottoms, and wetlands (McKinney 2002). Urbandevelopmentsareoften foundnear largebodiesofwater,estuaries,richproductive land,and/or riparian areas that are biologically important. The residual urban green spacesprovide refuges, resource sources, dispersal corridors, wintering habitat, and migratorystopoversforavianspeciesthattraditionallyreliedonthelandscapesthaturbanareasnowoccupy(Ohmart1994;Bolgeretal.2001;Mellesetal.2003;Sandstrometal.2006).Usingweather surveillance radars, a recent study has demonstrated that migrating birds areattractedtoareaswithmoreartificiallighting,usingthemasstopoversites(McLarenetal.2018).Thishighlightstheimportanceofpreservingandprotectinggreenspaceandparkswithsuitablehabitatwithinanurbanlandscape.WildResearch is a charitable organization whose goals are wildlife research andmonitoring, environmental education, and community engagement through training andoutreach. This organization believes that wildlife use in these semi-natural habitats isimportant for supporting wildlife communities, and should be further investigated. TheIIBOprogramservestoincreaseourknowledgeofsuchcommunities.

1.2. IonaIslandBirdObservatoryIona Island Bird Observatory (IIBO) has been in operation since 2010 and continues toserveasoneofWildResearch’scoreprograms.IIBOislocatedwithinIonaIslandRegionalPark, immediatelynorthof theVancouver InternationalAirport inRichmond,BC (Figure1),and ismaintainedbyMetroVancouverRegionalParks.Thisurbanpark isan isolatedpatch of riparian and meadow habitat that is surrounded by an expanding matrix ofresidential, commercial and industrial development. The park has been demonstrated inpreviousyearstoactasastop-overforavarietyofpasserines(IBACanada2017;Toochin2014a). It has been designated an Important Bird Area by Birdlife International and itslocal partners, Bird Studies Canada and BC Nature. The Sitka Foundation has providedsignificantfundingtoWildResearchforoperatingIIBO.

1.3. IIBOProgramsOverviewIIBO conducts three distinct avian population monitoring programs with the followingobjectives:

• SpringMigrationMonitoringProgram(SMMP),monitoringpopulationabundance,speciesdiversity,migratorytrends,localstopoverlength,andlong-termtrendsduringthespringmigratoryperiodasbirdsrelocatefromtheirwinteringgroundstotheirbreedinggrounds,

• FallMigrationMonitoringProgram(FMMP),monitoringpopulationabundance,speciesdiversity,migratorytrends,localstopoverlength,andlong-termtrendsinbreedingproductivityduringthefallmigratoryperiodasbirdsrelocatefromtheirbreedinggroundstotheirwinteringgrounds,and

• WintersongbirdmonitoringProgram(WSMP),monitoringwinterresidentspeciesabundance,diversity,andsurvivalrates.

• From May to August, 2017, through the Canada Summer Jobs program,WildResearchhiredaMScstudentfromSimonFraserUniversity,LauraNewberry,tocollectbaselineinformationonwildlifehabitatusageatIIBO,includingbreedingsongbirds. Findings from this summer research project can be found here:http://wildresearch.ca/wp-content/uploads/2015/10/WildResearch-2017-Technical-Report-and-Restoration-Plan-for-IBRP_180305.pdf

Overall these programs are designed to monitor the abundance, diversity, annualproductivity,survivalandstop-overecologyofbirdsthatusethisurbanpark.IIBOisoneofninebirdobservatoriescurrentlyoperationalinBritishColumbia,allowingtheopportunityto compare data at local and regional scales within the province. These programs alsoprovide educational opportunities whereby volunteers work alongside experiencedornithologists,learningtoidentify,safelyhandle,andbandcapturedspecies.

Birds banded in 2017 which were recaptured are referred to in the report asrecaptures.For ease of reporting, subspecies of Yellow-rumped Warbler (Audubon’s Warbler andMyrtleWarbler), Dark-eyed Junco (Slate- coloured Junco andOregon Junco), andTraill’sFlycather (Alder Flycatcher andWillow Flycatcher) are listed as separate species in thisreport.Moreover,hummingbirdswerenotprocessedorbandedbuttheywereincludedinthecountasnewbirds.

3. RESULTSANDDISCUSSION3.1. SpringMigrationMonitoringProgram

During2017,theSMMPrandailyfromApril15toMay31.TheSMMPincludedconstant-effortmist-nettingandcollectionofmorphometricandotherdatafromeachbirdcaptured.Banding was possible on 40 fair weather days during that period, for a total effort of2277.73nethours.A total of 2,806 bird captures from 50 species occurred during the SMMP (Appendix ATableA1).Thisisabovetheaveragespeciesrichnesscapturedinthespringbetween2010and2015(38species)basedonthecumulativereportforthoseyears(Table1)(KisselandScholefield 2016). The overallmean capture rate (1.43 birds/net hour) in 2017was thehighest compared to all previous years (Table 1). The highest number of birds capturedwasonMay4thwith286captures, followedbya fewsmallerpeaksonMay10thand18thwith164and189capturesrespectively (Figure3).Newbirdswerecapturedatarateof1.23birds/nethour, and464birdswere recaptured from35speciesat a capture rateof0.20birds/nethour.Thetopfivemostfrequentnewcapturedbirdsaccountedfor61%ofnewcapturesandlikepreviousyearswerenearlyallwarblerspecies(Table1;Table2).TheseincludedWilson’sWarbler,Orange-crownedWarbler,Ruby-crownedKinglet,Audubon’sWarbler,andYellowWarbler in respective order frommost to least (Table 2). These findings are consistentwith trends in the top species captured on Iona Island in the spring in previous years(Kissel and Scholefield 2016).Wilson’sWarbler, Ruby-crownedKinglet, Orange-crownedWarbler,AmericanGoldfinch,andSongSparrowwerethefivemostfrequentlyrecapturedspecies,accountingfor82%ofallrecaptures(Table2).Ofthetotalrecaptures,17%wererecapturedmorethanonce(AppendixATableA1).AgeratiosofSYtoASYbirdsforthetopfive species for newly captured and recaptured combinedwere between 0.5:1 and 2.1:1

(Table 2). However, not all birds banded during SMMP were aged into the SY or ASYcategories. This indicates that Iona Beach Regional Parks provide important habitat forbothyoungerandolderbirds.For the top five species during the SMMP, Ruby-crowned Kinglets captures were thehighest inmid-April, followedby a steadydecrease (Figure4a). This songbird species isknowntooverwinteratIonaBeachRegionalParkandlikelyincreasinglyemigratetootherareas to breed during the SMMP. Our capture data also clearly depicts differentialmigrationtimingamongst thewarblerspecies.Audubon’sandOrange-crownedWarblersdominatemostofthecapturesinearlyMay,whereastheabundanceofWilson’sandYellowWarblersbegintopeakinmid-May(Figure4b,c,d,e).All hummingbirdswere left unprocesseddue to their small leg size and their need for aunique banding method. As such, a different federal station banding permit is requiredwhich the IIBO does not hold. Therefore, no recapture data was recorded forHummingbirdsandallcaptureswererecordedas“new”.Other interesting captures included 2 Swamp Sparrows (Figure 5) which are noted tobreedfurthereastininteriorBCbutdooccurasanon-breederorpassingmigrantatIona.Townsend’s Warbler was another notable species, which are known to breed morefrequently inconiferous forests(Figure6).Only42Violet-greenSwallowswerecapturedthisyear,whereasin2011,thisspecieswasoneofthetop5speciestobecaptured,with143banded(Boyd2012).

In 2017 we captured 115 Golden-crowned Sparrows, which is known to be acommon overwintering species in the Lower Mainland. Yellow Warbler and Orange-crowned Warbler abundance peaked in mid-September and began tapering off by lateSeptember.Thisissimilartocapturetrendsofthetopfivemostcommonspeciesfromthe2016 (Owen 2017) and 2015 FMMP (Buehler andNathan 2016). YellowWarblerswerecompletely absent by October 7-9, as they migrate to Mexico and South America tooverwinter. In comparison, while most Orange-crownedWarblers overwinter in Mexicoand southern U.S., a small overwintering population is known to occur in the LowerMainland; this is reflected in the near-complete absence of their occurrence at IIBOtowardstheendoftheseason.ThetopfiverecaptureswereFoxSparrowsandSongSparrows,Black-cappedChickadees,Spotted Towhees and Ruby-crowned Kinglets (Table 4), representing 64% of allrecaptures. Of the total unique recaptured individuals, 24%were recapturedmore thanonce (Appendix A Table A2).

4.1. IIBOVolunteerSummaryDuringthe2017SMMP,44volunteerscontributed836.91volunteer-hourstohelpruntheIIBO banding station. During the 2017 FMMP, 37 dedicated volunteers donated 889.25hours.DuringtheWSMP,4volunteersdonated64hours(Table6).VolunteerscontributedsignificantlytoallofWildResearch’swildlifemonitoringprograms.Apart from contracted banders, everyone who contributes time at IIBO during themigrationmonitoringprogramsdoessoasavolunteer.Thedatapresentedinthisreportiscollectedbythesevolunteerswhocollectivelycontribute toover1,670hoursat IIBOperyear(nearlyequivalenttohiringafull-timeemployee!).Trainingprovidedbyexperiencedbanders resulted in many beginner volunteers rising to intermediate and advancedtraining levels, ensuring the continued success of themigrationmonitoring programs atIIBOandallowingvolunteerstogainpracticalbiologicalfieldskills.Manyofthevolunteershad little to no previous experience banding birds andwere very enthusiastic about theopportunitytobeinvolvedinbanding,especiallytheirfirstbirdinthehand.

4.2. EngagingthePublicandGroupVisitsDuring theSpringandFallMigrationMonitoringPrograms,groupvisits to IIBO includedthefollowing:

• DarrenIrwin(UniversityofBritishColumbia)• Naturekids• GilmourElementary • NatureKids• ThorVeen(QuestUniversity)• Environment&ClimateChangeCanada–CanadianWildlifeService

In 2017, more than 200 individuals visited IIBO during group banding demonstrationsincluding visits during the migration monitoring programs. Visiting groups includeduniversity/college classes, Nature Kids, and K-12 students. The IIBO station is gainingtraction as park visitors can experience close-up interaction with birds and learn newinformationabout thevariousbirdspecies thatuse IonaBeachRegionalParks. IIBOalsocontinuestopromotethepublictoparticipateascitizenscientiststoactivelycontributetoconservation science. In addition, this year WildResearch partnered with the CanadianWildlifeServicetoprovideabandingdemonstrationforthewinnerofthekid’sprogramofthePacificFlywayAmbassadorproject.Feedback fromleadersofvisitinggroups in2017lend high support for ourwork at IIBO, and adults and children alike are captivated bytheirexperienceofseeingbirdsinthehand.
