Yes, Swans do this .. How many times a Year.. I am not Sure.
You will see their Legs Shed also.

Avian – Swan Body Temperatures have a Wide Range
that is Related to their Activity.
IF you Need to Go to the Vets.. this might be Helpful..
Swan have a Higher Normal Body Temp then Human..
And their Temp will Vary by their Activity or Stress Level..
Anatomy SWAN Body Temperature

Like us, Birds are Warm Blooded, which means their Bodies
maintain a Constant Temperature, often around 104-106 degrees Fahrenheit.
Core Temperature in Birds Ranges between 34 and 44 °C
Birds Body Temperature Range is usually 39-43 degrees C (102-109 F)

Mean Levels of Body Temperatures (Tb) for all Birds are:
( Resting/ Active Phase/ High Activity )
( 102 to 103 F / 104 to 106 F / 107 to 109 F )
They have Ranges According to their Activity Level..
I Found only a Few Actual Bits of Data for Mute Swans Specifically.
Normal Ranges are Noted as Resting or Active..
Thermoneutral – Resting > >  39.5 degrees C – 103.1 degrees F
Active – Stress > > 41.1 degrees C. – 105.98 degrees F.

They are Prey Birds.. and Need a Wide Visual Field to see Danger.
Unfortunately, this Limits their Forward Vision.

Swans have Very Little Bite Pressure.
In ALL the Years I have been Working with Swans,
I have Never had a Bite that Cut or Punctured my Skin.
At Most their Bite is more of a Pinch.

A  Swan’s Esophagus is Located along the Right Side of their Neck. SWAN Esophagus-Food

You can watch the Food they Swallow Slide Down the Right Side. Mute Swan AnatomyI am going to Include the Following Series of Images Here.
Because this was a Worry until I Understood what I was Seeing.
 Mute Swan AnatomyWe were Visiting with our Swans – Lots of Greens, Vegetables and Treats.
Our Cob was Eating VERY Fast.. Loving the Goodies.
 Mute Swan AnatomyWhen he Stopped Eating.. He was Floating Quietly out on the Pond.
I Noticed this Swollen Area on his Neck.. and Wanted to Panic !
 Mute Swan AnatomyGood Grief WHAT was Wrong with his NECK ! 

It was Mid-Afternoon on a Sunday, NO Hope of Taking him to a Vet.

Once Home, I Started a Search for Swan Crops..  NOTHING.
 Mute Swan AnatomyCrop: A Pouch in the Esophagus used to Store Food Temporarily
before moving it on to the Stomach.
Waterfowl DO NOT Possess a True “Crop.”
Instead, their Esophagus is Capable of Expanding
to Accommodate Substantial Amounts of Food.

These Young Cygnets were EATING their Lettuce SO FAST..
And we would See the Right Side of their Necks FULL of Lettuce. Mute Swan AnatomySWANs are Grazers Normally Nibbling throughout the Day.
BUT, WHEN they “Pig-OUT” you may see this Pouching on their Lower Right Neck.

IF You See this and it does NOT Go Away..
Suspect your Swan Swallowed
SOMETHING that is NOT Digestible..
Swans can have Obstructions due to Swallowing Trash.

Anatomy Mute Swan Wing

Swans use their Beak and Head to do most of their Preening.
The Tiny Feathers on their Heads become Worn.
If there is Iron in their Pond Water, this Mineral attaches to these Feathers.
Air interacts with the Iron Particles and Rust forms.
This Rusty Cap will be Renewed to a Clean White during their Annual Moult.
