Norfolk Island Cuckoo ID

Thanks everyone for the response – pretty much universally agreed that it is a Pallid Cuckoo. Ironically, probably rarer than the Long-tailed Cuckoo I had hoped. I didn’t have my binoculars or field guide at the time, only my camera. As soon as I saw the images, I realised I hadn’t found a Long-tailed Cuckoo, but most of my bird books are packed and on the ship over to the island at the moment. I only moved to Norfolk a week ago, a Long-tailed Cuckoo in the first week would have been a bit too much to hope for.
