观察细节
2 flocks in close proximity to each other, flying directly over Cottam Point from Parksville towards Sechelt. Sound recording and photos attached. Not quite as large as Trumpeters. Unable to see yellow on bill, but group photo shows border of black on bills with face indicating Tundra Swan. Possibly there were other species of swan mixed in, but judging by the consistent sound coming from the flocks and the similar size of all individuals, they were all Tundra Swans.
