In the original lore, The Blues weren’t "clones"—they were a "Spread Bird." Shared Silhouette: The two birds without true abilities, Red and Terence, share a silhouette with the Blue birds. They are all part of the same baseline group.

Spread, Not Clones: They were called "Spread Bird" in the original lore, not "Clone Bird," because they are a single spread unit.

No Unlimited Multiplication: If they were actually clones, they would multiply unlimited times. But they don't—they are hard-coded to just spread into three.

The "Oblong" Problem: The other birds have weird, "oblong" shapes because they have those gimmicky, "weird" abilities. They had to sacrifice their silhouette to fit those powers in. The Blues are the only ones that kept the original silhouette while still giving you that tactical spread.
