Yesterday out at the farm I sat on the back porch trying to count hummingbirds. Five I think, 2 males and 3 females. It was very quiet. One of the males is a real character. He chirps constantly and loud---coming, going, and in between. Two feeders at opposite ends of the porch, required turning the head back and forth often and fast, and I heard it again, after years of not hearing it... The Snap, Crackle and Pop of the neck... .. The doctor in this video claims as long as there is no pain, there is nothing to worry about. It's normal. Does everyone hear those sounds?
