I finally managed to find an Ibis with clean feathers! Pity about the beak though 
I find these birds difficult, as their bodies are very white, and their heads are very dark. In the end I tend to overlay two exposures in photoshop, one for the highlites, and one for the shadows. (Which has the unfortunate side effect of making the feathers less white). Is there a better way of doing things?
Thanks for looking
