Good find, but I suspect that's quite a rare case - penguins have unique plumage and are also -- ahem, "quite flightless". It might seem I'm splitting hairs (or feathers!) but the "cold white dots" were quite uniform, these cuties are clearly hot/cold patterned - still a good example, bar the flightlessness.

Please tell me your feelings on the big picture. I feel it's imbalanced if you provide such certainty to some examples but refrain from a larger perspective. It's okay if you don't want to tho, I just want to know where you're coming from I guess.
