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.....:")

If those are Mute Swans, I give up.

It shouldn?t be this hard. 5 adult mute swans. No question there.=================NOTES TO SUBSCRIBER=====================
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.
