Group flying over house calling. Merlin ID as Tundra Swan - I listened to Tundra Swan calls on Sibley, Merlin and my Larkwire apps. The calls seemed especially like the NC calls recorded for Tundra Swans in the Larkwire app - and overall had similar cadence and tone to most of the Tundra Swan calls I encountered in my search - so I believe the Merlin ID to be accurate. I will include recording.
