Gang-gang NOVEMBER 2020 Newsletter of the Canberra Ornithologists Group Inc. NOVEMBER MEETING Summary/analysis of the past month and what to watch Wednesday 11 November 2020 out for this month Virtual meeting including AGM The weather for the 4 weeks from 30 September covered by this column has There will be another virtual meeting at seen average or above average temperatures, with regular and at least 7:30 pm on 11 November. The following moderate rain events, in keeping with the La Niña event officially declared is the webinar link: on 29 September. Based on this I would have expected fewer inland species in the COG Area of Interest (AoI) over the period. However, as detailed https://event.webinarjam.com/ below there have been surprising numbers of these, including again a couple register/67/zkonkh72 of species which I had not alerted readers to look out for in my October column. Participants should be encouraged to register at least 30 minutes prior to 7.30 The first of these was the Painted Honeyeater which COG’s 2108-2019 pm.

Following the AGM the presentation for the evening will be by long-term COG members Peter Fullagar and Chris Davey titled “The Rodent eradication program on Lord Howe Island - the COG contribution”. After many years of planning and delays, baiting with the rodenticide Brodifacoum was successfully completed on Lord Howe Island during the winter of 2019.

The Group has been responsible for the design and coordination of an annual survey of the lowland land birds since that time. The aims of the survey have been to determine the effects of the baiting program on the terrestrial birds after the initial baiting regime and in the long-term. The talk will discuss the problems associated with introduced rodents on islands, with examples of past successes and failures, how COG became involved, briefly introduce the survey methodology and then present some preliminary results and implications for rodent control on other islands. ______________________________________________ REMINDER: Annual General Meeting, 11 November 2020 The COG Annual General Meeting will be held at 7:30 pm on Wednesday 11 November 2020, as part of the webinar scheduled for that evening. Information about how to join the webinar will be emailed to members and published here http://canberrabirds.org.au/ category/meetings/ The AGM agenda and financial papers can be found here http://canberrabirds.org.au/about-cog/annual-reports/. The Minutes of the 2019 AGM are linked from the same page. Please advise any apologies to [email protected]. Please record your attendance by emailing your name to [email protected] during the AGM. The audited financial statement for 2019/20 has been loaded onto the COG website at http://canberrabirds.org.au/about-cog/annual-reports/ Summary/analysis of the past month and what to watch out for this month — continued from Page 1 birds were first reported by David Dedenczuk from the Mt Ainslie/Campbell Park eastern forest margin on 5 October, and since then up to 3 birds have been seen there by many viewers. It’s also a surprise that they seem to have stayed there, with on 23 October Alastair Smith reporting that 2 birds appeared to be collecting spiderweb as nesting material. So that is something to look out for, noting that Michael Lenz has previously mentioned they are very surreptitious breeders. In the interim David McDonald heard one calling intermittently over approximately five minutes but could not find it high in the canopy of a group of Yellow Boxes at the Sutton Common on 18 October, and Jenny Bounds observed one at Mulligans Flat during the COG Blitz on 23 October. So it’s worth keeping an eye out but especially an ear out for its very characteristic “Geor-gie” call which often gives a clue to its presence. Also unexpected was the return of the Common Sandpiper to the Isabella Pond, first reported by Kym Bradley on 4 October. Assuming it’s the same one as was first reported there on 7 October last year, it is remarkable how this small solitary bird can find this tiny spot on the map after having flown from mid to north latitudes in Asia where it breeds (a remarkable feateven if it’s a different one). Again it was recorded by a number of observers up to 28 October, but whether it will stay all summer as it did in 2019-2020 is unclear; perhaps there is more suitable alternative habitat in this much wetter year. Interestingly the closest location from where it has been recorded this spring is north of Wollongong over 200 km away. Gang-gang —November 2020 2 The third species I did not alert readers to look out for was the White- Australian throated Needletail of which 3, circling rapidly and widely overhead Ornithological in the wind currents, were first reported by Jean Casburn over Mt Services P/L Taylor on 2 October. Another 3 birds were then reported on 14 October by Deb and Rod Ralph on Tharwa Drive opposite Lanyon PO Box 385 Homestead. The reason I had not yet alerted readers to look out for South Yarra 3141 this species is that few are usually seen until their return northward Victoria migration in the New Year, which is generally accepted as a much more inland one. However, there may be more around in this much wetter Mob: 04173 10200 year, so please keep a lookout for this and the related Fork-tailed Swift. [email protected] The Masked Woodswallow, a species I had asked readers to look out for but wasn’t confident it would be observed in the COG AoI this spring, has been reported from 4 locations, first a single bird over the Good birding, good food Pinnacle NR by Jeb Kent on 1 October, 25 by Liam Manderson over Macarthur on 8 October and 20 by Luke Downey over Wamboin on 11 Personalised tours in the spring and early October, respectively. The latter were accompanied by 25 and 60 summer in the best seasonal conditions in White-browed Woodswallows, respectively. Nicki Taws also years reported a mixed flock heading NW over Cook on 4 October, while Michael Lenz reported 16 White-browed over Gundaroo that same Plains-wanderer weekend morning, and Viv Rolland/Angus Rae saw a single one at Campbell Park 14 — 15 November 2020 on 10 October. Top End birding tour The Horsfield’s Bushlark also seems to be present both earlier and in 10 — 24 May 2021 greater numbers than expected, with records from 6 locations Darwin, Kakadu, Katherine, Kununurra, between 14 and 23 October. This also applies to the Rufous Songlark Mitchell Plateau recorded from a surprising 25 locations, including some in the southern part of the ACT. In fact, there seem to be more present in Atherton Tablelands the COG AoI than in the dry 2019 spring. The White-winged Triller & Iron Range NP also seems to be present in surprising numbers as it has been recorded Cairns & Atherton from around 35 locations, though perhaps not as common as last 31 May — 5 June 2021 spring. In contrast the Brown Songlark has only been recorded from Julatten to Iron Range NP one additional location, West Belconnen Pond, but by a number of 5 June —13 June 2021 observers, initially by Michael Lenz on 16 October. The Pilbara NW WA Of the species which had yet to arrive by 30 September, the Channel- Two Pilbara tours in July 2021 billed Cuckoo was first reported from Ainslie by Steve Holliday on 23 Central Australia 6 —16 August 2021 Alice Springs, West MacDonnell Ranges, Glen Helen, Yulara, Erldunda, Marla Nullarbor Plain birding tour 5 to 20 September 2021 Plains-wanderer Weekends 2021 16 & 17 October 2021 30 & 31 October 2021 27 & 28 November 2021 Please see itineraries, checklists and latest news on our website. Plumed Whistling Ducks Geoffrey Dabb www.philipmaher.com Gang-gang — November2020 3 October, though there were 2 earlier reports from east of the COG AoI on 19 and 20 October. The Brush Cuckoo was first reported by Sandra Henderson from the Murrumbidgee Discovery Track between Kambah Pool and Red Rocks Gorge on 18 October, and then by Sandra and several other observers at Kambah Pool from 19 October. In respect of the passage migrants, one or two Satin Flycatchers have been recorded from 3 locations, two of these from peri -urban locations, the first being 2 birds at Bluetts Block by Peter Morris on 14 October. The Rufous Fantail has been reported from 2 locations, the first being the only peri-urban one at Campbell Park by Beck Redden on 18 October.
