quail
鷃 refers to a quail, a small ground-dwelling bird.
鷃 combines 鳥 (bird) with 晏, which likely contributes the sound. The character is used specifically for quail.
The right side is 鳥 (bird), and the left side 晏 suggests a small, peaceful bird. Picture a quail resting quietly under a roof (宀) with the sun (日) and a woman (女) nearby.
For アン, imagine an ant (アン) carrying a tiny quail egg: ant -> アン, and the quail watches.
