Geelong Field Naturalists Club
For many years an annual survey during the flocking season for Brolgas has been carried out to monitor breeding success of this endangered species. Total numbers in Victoria are estimated to range between 600 and 1,000. It is likely with changes in the distribution on suitable wetlands that Brolgas may be flocking at new sites, not previously recognised.
For the above reason it is important to look at not just historical flocking sites but also potentially new sites. An example of a new site that has been noticed recently is Green Swamp at Glenthompson after works by Nature Glenelg Trust to restore this wetland. The surveys must be undertaken on the same day by all observers.
This year surveys will be undertaken on two occasions, a month apart, on the advice of epidemiologists with the hope of producing a more accurate assessment of the population.
Like in 2023, we are calling for volunteers to survey known and potential flocking sites near Cressy and closer to Geelong.
Sites to be counted –
- Cundare Pool
- Lake Weering
- Reddies Road
- Armytage Road
- Lake Martin North
- Wetland on Eurack-Cressy Road near Mt Hesse Road
- Lake Murdeduke
- Sparrovale Wetlands
- Hospital Swamp
- The Western Treatment Plant – Austin Road Lagoon, Western Lagoons and Lake Borrie
What is required?
- Site and time of the survey – GPS coordinates preferred
- A description of the site and land owner details if access to property required, rather than surveying from roadside
- The name of the observer(s) and a contact number
- A full count of all Brolgas present and preferably an accurate count the numbers of Juveniles (Grey Cap), Immatures (Orange Cap) and Adults (Red Cap). A spotting scope is typically required for this.
