There'd been a lot of commotion up in the big angophora tree, the Noisy Miners had been trying to hunt the Channel-Billed Cuckoo to the outer limits somewhere, anywhere but where they consider their territory!
I decided to check for myself and found, way up high .......
I wondered at first were they the adult Channel-Billed Cuckoos in a gathering, coming to 'collect' the young-ones to fly them back to New Guinea? Hadn't really expected they did that in big numbers though. I cropped from the larger picture and sent it to Richard Major, an ornithologist working with the Australian Museum.
Though it was difficult to get a good impression, Richard suspected these are White-throated Needletails. Checking my bird book then, I'd say he is right on the money, with the shape of those tails being significant, appearing more wedge-shape rather than elongated. People can be so helpful if they choose to be; it made my day to have that verification; thanks Richard.
