Sorry, I haven't done a "bird of paradise", I've stuck mostly to North American birds. I think the ReMix model might be a good base for the Bird of Paradise with the tail plumes attached as a prop. And the cool thing with the ReMix model is that you get stationary and flight models in one model. Plus in my latest two SBReMix releases there are animated poses files for flight, landing and take-off. Was there a specific species of "Bird of Paradise" you were looking for? I think there's 20+ subspecies... or is the image posted what you're looking for?
