pheasant
鷩 centers on a specific kind of bird: a pheasant. The meaning is narrow and refers to this particular bird.
鷩 combines 敝 (likely a phonetic component) with 鳥 (bird), forming a character for a specific bird, the pheasant. The exact historical development is uncertain.
The top part 敝 looks like a broken or worn-out cloth, and the bottom is 鳥 (bird). Imagine a pheasant with ragged, worn-looking feathers, like a tattered cloth, making it easy to remember this bird.
For ヘツ, picture a pheasant with a funny hat: the hat sounds like 'hets' (ヘツ) and the bird wears it proudly.
