This bird finished a deep preening session with a big fluff and shake of the wardrobe.

Yes the square crop works for me, I like the pose, good details though I think there is just a possibility of getting more out of the dark head feathers and the yellow wattles.
Great bird on an interesting perch. When birds fluff out like this I always press the shutter, but for some reason I am rarely happy with the poses. This one is OK-ish. My personal opinion is that there is too much space above and therefore I would crop some out up there.
