Birds that treat lakes like furniture and wind like a free taxi.

means A bird that lives on or around water and is adapted for swimming or wading — ducks, geese, and swans are the classic examples.

from A plain old Germanic compound: 'water' plus 'fowl,' the latter from Old English 'fugol,' the general-purpose word for 'bird' before it narrowed to mean poultry and game birds specifically. So waterfowl simply means, with no hidden cleverness, 'water bird' — one of English's most honestly-labeled words.
