Sire – The Male Parent of a Brood of Cygnets.
Maiden Swan – An Adult Female Swan that has not yet Nested.
Generally from One Year to her Third Spring..
“Brood Patch” Summary:
By Shedding Contour Feathers from the Pen’s Breast-Abdomen into the Nest..
The Patch of Thinner Feathers Allows the Female’s Body Heat to Transfer
to the Incubating-Developing Eggs..
With Good Health and Care a Female Mute Swan may Live 20-30 Years.
Females have a Higher Mortality Rate During and Shortly after Nesting.
June 15th is the Mean Average Date for Mute Swan Eggs to Hatch.
Early Spring Nests Hatch From Late April to the End of May.
Late Spring Nests Hatch by the First Week of July.
We Celebrate June 15th Annually as “Happy Hatch Day.”
(A Swan’s Birthday Equivalent.)
Sitting or Standing Sentry.
During the Night Time Hours the Male Swan may Stand Guard
near the Nest while the Female and Cygnets are Sleeping.
Cygnet – A Young Swan from Hatching until One Year Old.
Swan Cygnets are Precocial.
Their Eyes are Open at Hatching. These Little Cuties just Hatched Hours Ago.
They are Covered with (Waterproofed) Down. Ready to Swim.
Swan Cygnets are Ready to Leave the Nest as soon as they are Fluff Dry and Rest a Bit.
When they Leave the Nest they are Ready to Eat on their own.
Swan Parents do not Feed their Young, but take the Cygnets to Places
where Food is Available for the Cygnets to Graze on.
Brood Call – The Cygnets all have Different Vocals.
They Chirp and Whistle to keep Track of Each Other.
Feathered Out – At about 4-5 Months of Age, Cygnets have their First Full Plumage.
When the Young Swans are Paired, Ready to Mate and Nest…
they will Leave this Group and Find their own Territory.
Grey Birds, Grey Swans – Young, but Full Grown.
Swans in the Grey Plumage of Immaturity.
The Stage between Cygnet and Blue-Bill.
Blue-Bill – A Young Swan up to its Second Autumn
– in Adult Plumage, but not having attained its full Adult Bill Coloration.
White Swans – All Swans in White, Adult Plumage.
Polish Mute Swans (Cygnus olor ‘immutabilis’)
are a Leucistic Form of Mute Swan.
A Leucistic Animal has a Reduced Intensity of Pigmentation
– while an Albino Lacks all Pigments.
When a Male Mute Swan Inherits only Melanin-Deficient Chromosomes,
he will be a Polish Mute Swan. The Polish Mute Swan Feet are Light Cocoa Brown to a Rich Chocolate Brown.
Their Beaks are more Orange than Red.
Royal Swan Cygnets – have Black Feet, Darker Blue-Grey Down and Black Beaks.
A “Rogue” Swan is usually Full-Winged..
They Fly onto your Pond from Out-of-the-Blue.
If you have NO Swan to begin with.. Great ! Enjoy.
Pinion – In the Eastern United States most Swan Breeders will Pinion
Female Swans on the Right Wing and the Males Swans on the Left Wing.
A Properly Pinioned Swan will not be able to Fly.
A Sad but Necessary Procedure.
The Best and Safest Time to Pinion is within
23-72 Hours Up to 14 – 20 Days Old.
The Female’s Knob is usually a Bit Smaller.
The Female’s Knob will also Increase in Size during Mating Season.
The Knob is NOT a Good Way to Determine the Gender of Mute Swans.
– The Knob will Shrink if a Swan is Underweight.
– Some Mature Female Mute Swans have fairly Large Knobs.
– The Knob is mostly filled with Fat Tissue.
– It can Freeze during Extreme Cold.
– This may Result in Pink Scarring.
Beak-Bill – Two Bony Projections —the Upper and Lower Mandibles.
A Bony Modification of the Skull.
An External Anatomical Structure of Birds which is used for Grooming/Preening,
Manipulating Objects, Probing for Food and Eating..
Swans do not have much Bite Pressure.
They are able to “Pinch.” Maybe causing a Scratch if you Pull Away.
The Beak-Bill is Covered with a thin Keratinized Layer of Epidermis
known as the Rhamphotheca.
In most Species Two Holes known as Nares Lead to the Respiratory System.
The Nail is used to dig into Roots and Tough Fiber Parts of Plants.
Lore – The Area on the Head between the Eye and the Base
of the Upper Part of the Beak.
In Birds they contain Branched Bones or Cartilages called Turbinates,
whose Function is to Warm Air on Inhalation and Remove Moisture on Exhalation.
Nether Chap – Lower Mandible of the Beak.
Lamellae – The Serrated Edge along the Bill/Beak is called the Lamellae.
This Aids Straining Water as the Swans Eat Watery Foods.
Plumage – The Feathers
They Moult every Year during the Summer Months.
The Pens Moult during late June and the Cobs Moult during July.
For a Short Time the Swans will look a bit “Shabby.”
During this time they are Unable to Fly.
It takes about Four – Five Weeks for all the New Feathers to Grow-In
and become Firm Enough for Flight.
The New Feathers are “Blood Feathers” and can Bleed PROFUSELY
if Broken or Cut.
Molt – Moult For Swans: Moulting is the Periodic Replacement of their Plumage
by Shedding Old, Worn Feathers as New Ones Grow-In.
Shabby or Shaggy… Same Stage.. Shaggy Moulting
The Stage after the Large Wing Feathers have Fallen Out.
The Swans look “Shaggy” when they hold their Wings in Display.
Blood Feathers – The Stage of New Growth of the Larger Feathers
when there are Blood Vessels in the Feather Shaft.
These Blood Vessel in the Feather Shaft will Atrophy over Time.
Nictitating Membrane – A Transparent or Translucent Third Eyelid Present
in some Animals and Birds that can be Drawn Across the Eye for Protection
and to Moisten the Eye while also Allowing Visibility.
In Swans, the Nictitating Membrane Closes Horizontally (side to side)
Across the Eye instead of Up and Down like a Normal Eye Lid.
Socialized – Frequent Interaction with Friendly People.
These Swans will come for Food Item and Treats.
Watch Males – Cobs for Aggressive Behavior.
Their Behavior Changes during Mating-Nesting Season.
UnSocialized – Swans will Keep their Distance when People Approach.
They are Less Vulnerable to Humans who might Harm them.
Especially when a Pair of Swans are Nesting and the Male is Protecting their Territory.
Be Careful.. This may Lead to the Swan Flying at you. Move to a Safe Place.
Their Increasing Reproductive Hormones DRIVE them to Protect their Pond,
Female and Nest Area. They will Chase and Defend.
Swan Cobs are “Hormones with Wings.”
This is their Job. Try to Give him SPACE and Understanding.
Flog – Flogging – Swans Whip and Beat with their Wings in a Repeated Action
as their Primary Aggressive Defense.
Preening (of Birds) – To Maintain Feathers in a Healthy Condition by Cleaning,
Arranging and other Contact to their Feathers with their Bill.
Swans may Preen One to Two Hours a Day.
Often done after their Splashy Bath.
Oil is Rubbed through the Feathers to Aid WaterProofing for Buoyancy.
Preening Fluffs Air into the Feathers for Insulation.
They will Stand along a Bank Together and Preen.
Expressing an Acceptance of Each Other.
The Swan Transfers this Oil to its Feathers by Rubbing its Head against
the Oil Nub and then Rubbing the Oil all over their Body.
Along with the Air in the Lungs…. Swans FLOAT…..
Heel – The Hind Toe
Cloaca -Vent In Zoological Anatomy, a Cloaca is the Posterior Opening
that Serves as the only Opening for the Intestinal, Reproductive, and Urinary Tracts
of certain Bird Species.
Vent – The Opening for the Elimination of Digestive Waste.
Cloaca – Vent
The Area where Gender Sexing might be Determined.
If you Locate a Penis… It is a Male…
But, not finding it DOES NOT mean you have a Female…
Not a Sure Method for Sexing Swans.
They will Spend most of their Time Together.
They will learn to Work and Play together,
Court, Mate, Nest and Raise their Young together.
Mating – I refer to this as the “Mating Ballet.”
Mating Ballet (noun)
A Classical Dance Form demanding Grace and Precision
and Employing Formalized Steps and Gestures Set in Intricate,
Flowing Patterns to Create Expression through Movement.
The Rising-Up – Once the Sperm is Transferred to the Female, the Pair will Turn
and Face Each Other and Foot Pedaling Breast to Breast UP Above the Water.
HARDWARE Disease – Swan are Attracted to Shiny Things..
Shiny Metal.. Hooks, Coins, Hardware like Nails, Screws, Soda Can Tabs,
Rings, Jewelry, etc. Small Pieces of Litter.
Swallowed Metal will not Pass through their Gizzard, it Slowly Dissolves
becomes Toxic, causing Heavy Metal Poisoning or Fatal Punctures.
Winter Wakes – Selected Areas of Water in which the Ice is Kept Broken
or Open for the Accommodation of Swans.
Waking Time – Periods of Hard Frost during which Wakes are Kept OPEN
and the Swans are Tended and Fed.
Making and Keeping OPEN Wakes (Water) for them.
Tending and Feeding Swans during Periods of Snow and Prolonged Frost.
WILD Swans – are Native Swans Living Free to Migrate.
Mute Swans – are Exotic Domestic Poultry.
Captive Swans – are Living in the Care of Humans.
Feral – Living Free – Returning to Living Wild from a Domestic/Captive Life.
Feral Animal/Swans that are Living in the Wild.
They may have Escaped from Private Ownership or Descended from Domesticated Pets.Examples: Full-Winged Swans or their Cygnets that Simply Fly Away from Private Property.
Excessive Pressure or Breaks in the Skin may cause these to form.
These Infected Sores Need Attention, they may Result in Permanent Limping, Difficulty Walking.
The Infection may become Septic, Spreading through the Body… Increases Mortality.
Aviculture – Raising and Care of Wild Birds in Captivity, for the Breeding of Game Stock,
the Perpetuation of Declining Species, or for Display and Education.
TAXIDERMY – Best to Keep Mute Swans from Living Feral & Free.
Addling – The Act of Causing Fertilized Eggs to Lose Viability,
Killing the Developing Embryo by Shaking, Piercing, Freezing
or Oiling, without Breaking the Egg Shells.
SPAY – Sterilize a Female Mammal by Removing their Ovaries.
NEUTER – Sterilize a Male Mammal by Removing their Testicles.
Remember Swans are NOT Mammals..
Their Reproductive Organs are Not Anatomical Similar.
