Meetings are held at 7.30pm on the third Tuesday of every month. 


Visitors are welcome to attend two meetings before joining CBOC.  Interstate and international visitors are always welcome.

Meetings usually consist of:

  • A short presentation on a specific "Bird of the Night", including identification tips, distribution and other interesting information

  • A Guest Speaker, often an expert in birding research or conservation, either locally or internationally

  • An update on upcoming activities and events

  • Information on bird conservation activities

  • "Interesting Observations", where members can share any recent unusual sightings


Then it's time for supper and a chance to meet other members over a cuppa. So come along and join us for a friendly and informative evening.

While masks are no longer mandatory, we encourage you to wear a mask.

Find us here:
