Great Crested Grebes courtship display 4 of 4. During the courtship ritual, Great Crested Grebes display black and orange facial ruffs and black ear-tufts known as tippets, which they use in a special ceremony to establish their bonds in the breeding season. Facing each other, the grebes flick their heads from side to side. [source description: BBC Earth]. Schardam, Netherlands.
