pheasant
鵫 refers to a pheasant, a type of bird. The meaning is specific to this bird species.
鵫 combines 鳥 (bird) with 卓, which likely contributes the sound. It is a phono-semantic compound for a type of bird.
The left side 卓 suggests something outstanding, and the right side 鳥 is a bird. Imagine a pheasant standing out with its brilliant plumage among other birds.
For トウ, picture a tall (高い, たかい) pheasant: the first syllable た reminds you of トウ, and the bird's height makes it stand out.
