quail
鵪 refers specifically to a quail, a small ground-dwelling bird.
鵪 combines 鳥 (bird) with 奄, which likely contributes the sound アン. The character was created to represent a quail.
The left side 奄 looks like a big 大 over a sun 日, and the right side is a bird 鳥. Picture a quail hiding under a large sun-like bush: 鵪 is a quail.
For アン, imagine an ant carrying a tiny quail egg: ant -> アン, and the quail watches nervously.
