Possibly 5. When they were interacting it was hard to see them individually because when they would fly low the land would become the backdrop and the low light made it hard to keep track of them. When they flew up they were silhouetted. I got to a count of 5 at one point but can’t be completely sure one of them wasn’t double counted as they flew at each other, in and out of silhouette.
