may have been more than 3 in this flock of about 300 Little Corellas, they were very active. The first 3 photos also show Little Corellas, the last photo shows part of the flock.
I wouldn't call image 4 a long-billed - the red is quite dark but don't think there is enough of it. Good to get them in my local flock though, I think I've only seen one once in it at the fadden roost.
