I don't think it looks crude; you must have done a good job with photoshop, then...
Funny enough, there are birds called "blue-footed boobies." You could always draw your coworker two of those together, if you are feeling a bit obnoxious. There are also birds called "tits." Oh man, so much fun to be had with bird names...
Trust me the name is already funny XD I'm from Poland, Polish for Bullfinch is Gil, gil is also Polish for a nose booger... So I just keep telling people it came of my nose lol.
I like color-full birds!
