My First Trumpeter Swans

For some reason, I had heard of Tundra Swans and when I saw these, I thought that that is probably what they were.
Then I heard some flying overhead and they made a brassy honking noise and I thought they may have been Trumpeter Swans which I had definitely heard of.
After reading up on both species and seeing that Trumpeter Swans are very few in numbers, I presume that they are Tundra. Is that correct?
Identified as Trumpeter.
It was snowing when this was taken.

they look more like Trumpeter swans to me... I saw them in Yellowstone years ago...so I'm no expert.. The Tundra swan images I saw online seem to have a yellow patch near the base of the bill.
nice photo of them

Great capture they do look like they have lots to say, will have to take your word on the type of swan:)

[Peter Grave]

No help from me Terry.The only ones i know are either black swans or white swans !! Nice shot.

@hrs I'll defer to @ribbet9 and @mjalkotzy

[Merrelyn]

A lovely shot, whatever they are :)

[Martin Jalkotzy]

Agree with @hrs , trumpeters. I have seen both, and the yellow patch of a tundra should be visible in the adults.

Great shot for these birds who love to move, I know mine were Tundra since the sign said so hahahaha. They do have slight differences though.

[Taffy]

I like how you've caught them with their mouths open -- they are such noisy creatures!

[Lee-Ann]

Great shot of these great looking birds.

[Denise Wood]

I can hear them now!!! great capture of your first trumpeter swans :)

[Sam]

Do they sound like a trumpet?

[Poppo Livy]

@gigiflower More like a French Horn Sam. I believe the foxes run like hell when these swans fly over

[Sam]

@terryliv Mmm, will have to go to you tube and see what the differences are between a trumpet noise and a french horn!

Lovely capture of that flock.
