The formal guidance for submitting a sighting to any of the Eremaea bird lines is 'rare or unusual birds outside their normal range, unusually high or low numbers, early or late arrivals or departures for migrant species and interesting behaviour or unusual habitat usage'. My advice is if you think your observation would be interesting to a wider audience, then please submit to Birdline ACT. All sightings are moderated and either assigned 'highlight' or 'normal' status. The moderators (currently Frank Antram and I) may in some instances decide not to post a sighting, in which case we will contact you to explain our reasoning. You can also submit photographs with your sighting (without any size restriction).
A major benefit to COG of you using Birdline ACT is that each submission is geocoded so that sighting, temporal and spatial information is collated and this data can be imported into the COG database. Presently there is no system to skim your reports from Canberrabirds to the database.
You can see what else has been submitted by visiting the site or by subscribing to the feed by use of an RSS reader. Or you can

Should you need any help at all with the site please contact me.
Give it a try.
