1 NSS 6 th Parrot Count 2016 Report Authors: Albert Low and Alan OwYong Introduction The World Parrot Count was initiated six years ago by Michael Braun and Roelant Jonker from the parrot researchers’ group of the International Ornithological Union (IOU). A key objective of the study was to document the status and abundance of feral and non-native parrots in urban environments globally where populations are established. Being part of this study provides an excellent opportunity for us to also monitor native parrot abundance and diversity in Singapore beyond our nature reserves. Given that some species such as the non-native Red-breasted Parakeet (Psittacula alexandri) have increased in abundance across Singapore, it is also timely to identify areas where these species are concentrated and their roost sites.

ResultsandConclusionsCoordinated annually by the Bird Group since 2011, this year’sParrot Count took place on 27 February 2016. 16 sites acrossmainlandSingaporewerecoveredby33surveyors.Thisyear’stotalof 2,483 parrots of 8 identifiable species is slightly lower than the2,725parrotsof7speciesrecordedlastyear.Aswasthecaseoverthepast2years,thewell-woodedMountRosiewasthemostspecies-richsite,withsevenspeciesofparrotrecorded.BottleTreePark,asitefirstsurveyedin2015,wasonceagainthetopsite in terms of total abundance, with 892 individuals from twoparrot species recorded. The Long-tailed Parakeet (Psittaculalongicauda) was the most numerous parrot recorded during thecount, with a total of 1,837 individuals seen, a decrease from the2,059 individuals observed last year. This constituted 73.6% of allparrotsrecordedduringthecount.526Red-breastedParakeetswerealsorecorded,makingupthebulk(21.1%)oftheremainingparrotsrecorded.OtherspeciesrecordedincludesmallnumbersofTanimbarCorellas, (Cacatua goffini), Coconut Lorikeets (Trichoglossushaematodus), Rose-ringed Parakeets (Psittacula krameri), Blue-crownedHangingParrots (Loriculusgalgulus) and4Yellow-crestedCockatoo(Cacatuasulphurea).During the census, parrotnumberspeakedbetween7pmand7.30pmwhere1,683parrotswere counted.As shown in recent counts,the largest parakeet flocksweremainly observed at last light,withcounters atmany sitesmanaging to observe the noisy spectacle offlocks of parakeets returning to their roosting trees just beforecompletedarkness.With a second year of data collected from pre-roost staging areasthroughoutcentralandnorthernSingapore,theannualparrotcountis nowproving to be useful inmonitoring the large flocks of Long-tailed Parakeets which travel along the eastern boundary of theCentral Nature Reserve to roost sites in the vicinity of Yishun viastaging sites in Springleaf.

These findings have important conservation implicationsfor the globally near-threatened Long-tailed Parakeet, and go someway towards alleviating fears that the recent expansion of the

It is hoped that annual surveyslike the Parrot Count will also provide a platform for monitoringtrendsrelating toother introducedparrots like these inaddition tothemorenumerousparakeets.Last but not least, the organisers would also like to reach out tovolunteerswho are aware of Red-breasted Parakeet roosts in theirneighbourhood and are willing to survey them. Anecdotalobservations show that while Red-breasted Parakeets arewidespread and common in urban Singapore, many of their roostsiteshaveeithernotbeen locatedasyetorareotherwisenotbeingcounted. It is hoped that with an increased pool of surveyorscountingatmoreroostsitesthroughoutSingapore,amorecompletepicture of the local Red-breasted Parakeet population can beobtained.
