Just wondering about the numbers in Glossy Black (Cockatoo) flocks. What's the highest number of birds in in one flock?
The highest number I've seen was 14 in BMNP - we observed them drinking from a creek which we were camped at! Otherwise I've only seen them in trios an pairs.
(I hope this is the right forum to post this in!), Thanks









The most I've ever seen was about half a dozen near Mt Bushwalker in Morton NP near Ulladulla. But then, that's the only time I've ever seen any- seen huge numbers of Yellow Tailed Blacks before at Abercrombie NP due to the pine plantations nearby though.
BMNP stands for Blue Mountains National Park, Owl of Kedumba?
Yes Woko
Ta!

each day, early morning an in late afternoon when they return, they fly over my place in 2 x two pairs but also in three, usually a young one in toe, but this time of the year numbers around , nine to fifteen birds fly thru are common.
See it! Hear it!

It seems glossy black cockatoos & yellow-tailed black cockatoos breed one young one per brood. Most times I've seen yellow-tailed black cockatoos, especially around breeding time, the numbers divide by three quite nicely.
Recently saw a flock of +9 Glossy's
Personally I've never seen more than three Glossies around Sydney's west and the BM area. :(
Yellow-tailed Black Cockatoos though...... probably 20 or 25 is as many as I've seen in a group.
Speaking of Yellow-tails, I've seen 2+ every single day this month (Feb) except on the 27th. The most was about 8 but apparently they're gathering around Lyrebird Dell. Should see them in flocks in the coming months I hope.
