While at work me and my coworker saw 2 ufo’s hovering in the sky. We first thought it was balloons but it wasn’t balloons

Me and my coworker at 8:25 pm saw two objects hovering over in the sky with birds. The birds were flying around it and led it into the clouds. The object looked like a bike almost then it had a weird shape to it like a spikes. We thought it was balloons at first but then the longer we looked at it we realized that it was something much more extravagant. It was an object that looked like a person was on it riding a bicycle. We took pictures of the object but couldn’t fully make it out in the photos. It looked very dull and black.
