RE: Doe bellowing like a cow??
What that is called is a ready call for a buck. I here it all the time and have done the call a couple of times in December with luck. The sound she is making is telling her fawn to stay put and alerting a buck she is ready. I will find the article on it I wrote and post it. There is also a sound a doe makes when they are going to die. Its a gurgling sound from the lungs.
