Chinese oriole
鸝 centers on a specific bird: the Chinese oriole. The meaning is narrow and refers directly to that bird species.
鸝 combines 麗 (likely contributing sound) with 鳥 (bird) to name the Chinese oriole. The exact historical development is uncertain.
A beautiful (麗) bird (鳥) with striking plumage: that is the Chinese oriole.
For リ, imagine a Chinese oriole perched on a lychee tree: lychee -> リ, and the bird sings among the fruit.
