Milan Metthey's experiments were concerned (for this project anyway) with the mallard duck. He went so far as to create a duck mask that was constructed from his own facial features and then attempted to interact with the ducks.
From Good Magazine:
"As cities continue to grow, spreading outward across the landscape and into each other, it's worth thinking about how experiments like Metthey's might help us design urban ecologies that function equally well for all their animal inhabitants."
