I was thrilled on Thursday when a small flock of Tundra Swans (Cygnus columbianus) flew overhead while I was at Occoquan Bay National Wildlife Refuge. It is rare for me to see swans of any kind in this area. When I spotted the formation approaching, I initially thought they were Canada Geese, but as they got closer I could tell that they looked different and sounded different.

I hope they were heading north and bringing spring with them, Mike. Great photo.
I didn’t check their direction, but I suspect that their internal GPS will be sending them north soon. 🙂
Great formation.
We may get to see Sandhills migrate soon!
