Identify this trashy Italian zombie movie

Okay, now I have my question to pose to the movie geeks at the SDMB.

I only have very limited info on this movie, I’m sorry.

One thing I know of is that it contains a very obese male zombie, whom rips open his stomache. His intestines become animated, and strangle someone. He also sits on someone and crushes them, I believe.

Another character is a zombie with his skull cap opened like a flap, which at one point closes in, trapping a bird inside of his head. For a portion of the film, he walks around with two wings sticking out from his head.

Please, help me. Thank you.
