Alien Birds

The above image is Kevin from the movie Up. Recently I was watching some classic Looney Tunes, specifically Hare Way to the Stars (1958), and noticed that the bird-like alien in that episode looks kind of similar to Kevin. Or rather, Kevin looks similar to it as it was obviously drawn first. I wonder if this is a coincidence or intended?
