I found these cute little Gang Gang Cockatoos, playing on the ground of their aviary in the Loro Parque / Teneriffe. They were playing and cuddling each other for minutes and I was able to make some pictures.
There was not much light coming through the vegetation and I had to make the pictures with really slow shutter speed.
I would love to have a different crop were the Marking Ring on the foot would not be so obvious, but I don't know, if another crop will work....

They do have a nice "curve" to them. You could crop as a vertical which would eliminate the leg/band but you would lose the bigger picture of the curves. You could clone the band out if you don't find that objectionable. You could crop it closer at the top to eliminate the bright spots.
Interesting behavioral capture, Rosl. I like the appearance of the bird on the bottom, but wish some of the face and eye of the top bird was visible. I think that's a bigger problem than the composition and/or the leg band. I think the comp you have here is as good as any for this image.
