Trumpeter would fit better with my initial impression that immatures were
similar size as adult/white birds. Tundra are 2/3 the size of those two species
by mass. That should be readily apparent if the two groups are seen closer
together than they were when I was there this am.
As in my last email, my call of Tundra from Eric's photos was mainly due to
isolated eye and fairly light grayish brown overall coloration. I agree that
head/bill shape has a somewhat Trumpeter look which is troubling. Especially if
eye isolation isn't as reliable in immatures. Those eyes are REALLY isolated
though.
There was a lone immature in Asheville last winter that caused a lot of debate.
I don't know that it was ever resolved.
Without a scope, I didn't go back out after work. Maybe this weekend.

Juvenile swans can be one of the toughest ID's out there. I wouldn't discount
the possibility at all of these being Trumpeter. The shape of feathering at
the base of the bill, doesn't really work on birds of this age, as it isn't
fully developed. Same goes for the extent of the black loral area, this can
take a while in young Trumpeters to reach its full extent. The head shape in
all of the profile shots, to me, has the classic Canvasback like profile of
Trumpeter, vs the change in angle where the forehead rises away from the bill
typical of Tundra. Just a different opinion and take on these birds....not
saying they are Trumpeter, but this was my first impression on these birds.
The extent of pink, or lack thereof, probably doesn't sway one way or the
other, though many Tundra are still more extensively pink than this group
overall (but not a rule).
Anyway.....:")

I do not think these look like Mute Swans.

So Eric Bodker has some up-close photos of the immatures from yesterday in
eBird and the TN Facebook page.

If those are Mute Swans, I give up.

It shouldn?t be this hard. 5 adult mute swans. No question there.
4 first year what? They are clearly keeping to themselves most the time.
They do appear slightly smaller but not 10 inches smaller. They have very
deep pointed foreheads similar to trumpeter and mute. Their tails are
clearly not long like the adult mutes. Eyes are pretty offset like mute
and tundra. Head meeting upper bill profile very smooth and straight more
like a trumpeter.
At this point I have to go with Mute Swans on the 4 younger birds but I?ll
be interested when some experts weigh in.
