We know from Big Bird’s extended family that his species has a wide spread of individual variation, and given that none of them reside in the wild none of them are likely to suffer predation due to what would otherwise be a mal-adaptation, providing a springboard for even more genetic variation from generation to generation.
Just look at how wildly different looking specific humans can be from one another, even within a single community.
Big bird has forward facing eyes, which is usually the mark of a predator.
Maybe it evolved from a predatory ancestor and didn’t get selected for different position of the eyes?

And dragons have wide-set eyes in pretty much every depiction. So that brings up the question: What was hunting all the dragons?
