a bird built like a fishing pole that walks on its own dinner table

means A wader is a long-legged bird that feeds by walking through shallow water, or alternatively the waterproof waist- or chest-high boots an angler wears to do much the same thing.

from From the verb 'wade,' which goes back to Old English 'wadan' — to go, to move forward, especially through something that resists you like water or mud. It has cousins across the Germanic languages and is likely related to Latin 'vadere,' to go (the same root that strides through 'invade' and 'evade'). So a wader, bird or boot, is simply 'a thing that goes through' — the agent suffix '-er' turning the act of slogging into a noun.
