Golden Boomerang Object Circling Above South St. Paul, MN in Early 80s

I'm 26 now, but I'm not sure if this will help or be considered valid since I was so young. I was 4-5 years old, lying in bed staring out the window up at the night sky, when I noticed an object circling above. It was boomerang-shaped, golden, and circling the duplex my family lived in and the home next door. After watching for a while, I got out of bed to tell my dad (who was watching the late news) about the "ghost bird" flying above the house. He told me to go back to bed. When I did, it had left. However, I woke up later on in the night, and it had returned. I called it the "ghost bird" for a long time, until I found out about UFOs. I hope this helps. Thanks.
