Good morning COG members and chat line subscribers, a reminder that the October normal COG meeting will be held tomorrow evening Wednesday 11 October at our usual Canberra Girls Grammar School venue from 7:30 pm. Details are below.
Everyone is welcome so please come along to listen to two very different presentations. You will learn about an important environmental organisation of which I expect very few of us are aware. Also attendees should be very keen to hear
about the social lives of Sulphur-crested Cockatoos in Sydney (you may have seen them on Ann Jones TV program) and Canberra, including why we have been seeing colour-marked birds locally.
There will be the usual raffle and you will also be able to enjoy a cup of tea or coffee after the meeting.

The October meeting will be a normal face-to-face one held at our usual venue. Attendees should heed social distancing and good hygiene practice etc, and use their common sense and stay home if they have
COVID symptoms. Mask wearing is recommended.

Julia Penndorf -
Cockatooing around – the social lives of Sulphur-crested Cockatoos in our cities
The first speaker will be
Lori Gould, Program Manager at the ARRC, on “River Restoration and Management – Rivers of Carbon”.
Our rivers are facing many issues that cause degradation of biodiversity and water quality, which affects everyone. Issues include erosion, weed invasion, unfettered livestock access, loss of biodiversity
– in particular, important riparian vegetation, and barriers to fish movement. There are solutions though. One example of a program that addresses these issues is the Rivers of Carbon (RoC) project. This is on the on-ground program of the Australian River
Restoration Centre (ARRC) and operates in an area covering Cooma to Sydney, Yass, Crookwell, and Boorowa.
Since 2012, the RoC team has worked with 161 landholders, planted 112,434 trees, fenced 158 kilometres of waterways and restored 1331 hectares of riparian land in south east NSW. The model helps landholders
protect their water resources, reduce soil loss, improve biodiversity and ecosystem functions (such as natural pest control) and better manage stock in adjacent paddocks by providing shelter and clean water by accessing incentives for fencing, stock water,
stock crossings, small-scale erosion control, revegetation and woody weeds. The program focuses on working with farmers personally while achieving regenerative agriculture outcomes. This results in clean water, better stock management and importantly, improvement
in biodiversity and habitat for birds and other animals.
The main speaker will be
Julia Penndorf, a postdoctoral fellow at the ANU, on “Cockatooing around – the social lives of Sulphur-crested Cockatoos in our cities.”
Sulphur-crested Cockatoos are large, charismatic, rockers ever present in our urban environments – but how much do we really know about their social lives? The Cognitive Ecology Group at the Research School
of Biology, ANU, focuses on the social and cognitive ecology of urban Sulphur-crested Cockatoos. As part of their research, in 2023 they have temporarily marked over 900 cockatoos across 8 roosts in the inner North of Canberra, combining these observational
approaches with active GPS tracking of over 100 individuals. Julia has been studying their social associations and wider movements and will present some of her findings from both her past research on Sulphur-crested Cockatoos in Sydney, as well as preliminary
findings about the social landscape of these birds in Canberra.
