cormorant
鵜 refers specifically to the cormorant, a water bird known for diving and catching fish.
鵜 combines 弟 (which likely contributes the sound) with 鳥 (bird), forming a phono-semantic compound for the cormorant.
The left side 弟 (younger brother) and right side 鳥 (bird) together suggest a bird that is like a younger brother among water birds—diving and working alongside fishermen. Picture a cormorant as the fisherman's helper bird.
For テイ, imagine a cormorant taking a fish from the water: take -> テイ, as the bird takes its catch.
