There were eight. The story behind it is that as we were driving I was looking through the guide and said I would like to find a Greater White-fronted Goose because they were seen in this area! When we got out to look for the Tundra swan I looked over them in my haste to check out the swans. Dad saw them and the swans lost our intrest! ;D ;D We did check out the swans, there were probably 35 Trumpeters.
