A childhood belief about birds

My family moved to England when I was five. I had previously lived in South Africa, and had never seen or heard a pigeon before. Often in the early morning I heard a distinct, repeated "coo coo" sound coming from outside my bedroom window. Overwhelmed with curiosity at the strange noise, I would race over to the window and fling the curtains open to see what it was. But all I could see was the moon in the sky (the pigeon was sitting above my window well out of my sight) Not able to see the bird, I immediately connected the moon with the noise, and for years after thought the moon made cooing noises in the morning.
