You are going to be sad we the biologist you worship change their stance on population decline. Have you ever noticed how the “Science” is always changing? That’s because the “biologist” don’t have a freaking clue what is going on with the population. Your problem starts with your lack of personal knowledge. You can’t believe what some dipstick setting behind a computer tells you about the outdoors. Get out of the city and see for yourself. No I don’t believe you hear 7-8 different birds gobbling. I think you lie to help your point. I’ve been turkey hunting for 39 years and left more knowledge in the stool this morning than you will ever have or gain from your concrete jungle and your computer. I’m changing your name to Gretta the turkey expert!I dont care about his opinion because it is uneducated and uninformed.
