Okay, some people are getting confused. The mallard is not a crested anything. It's a tufted. That is not a tumor; it's a tuft of feathers. Do you guys not recall the whole convo not long ago about tufted ducks?
Rob even labeled the photo as a tufted mallard. See?
Suddenly you've got tumors growing out of it's head. C'mon guys!
Here's the convo about tufted ducks from the 20th & 21st of Dec.
