The Falcon That
Flew With Man
Peregrines
occur in every continent except Antartica.
The Peregrine Falcon has the honour of being
the fastest creatue in the natural world.
She can be identified in adult plumage by her blue grey back, cream
chest with vertical black bars on legs and aabdomen. Her head is dark
capped with a dark stripe, known as the malar stripe below her eyes.
Her wings are long and tapered and she has a
shortish barred tail. She will have yellow legs and proportionally large
yellow feet, perfect for binding to her prey in flight. Her bill is
pointed, dark grey and equipped with a 'tooth' on each side to assist
her in breaking the vertebrae of her preys neck. Immature falcons are
identified by their brown plumage.
A female peregrine is known as a falcon and the
male a tiercel, he is about a third lighter than the female.
The shape and form of a peregrine is the ultimate
in design for making her streamlined and aerodynamic. She can achieve
speeds of over 300kph in a stoop and is capable of making strategic
decisions in microseconds. To protect her when stooping in high speeds
she has an additional eyelid, known as a nictating membrane to protect
her eye and in her nostril she has a central cone to stop her from blacking
out.
Her eyesight is truly amazing as they have two forveas. One of them
has five times as many visual cells than ours and is shaped like a telephoto
lens, enabling her to see prey as far as 10 kms away.
A
peregrines diet can very, they are capable of taking a wide variety
of prey, pigeons, duck, grouse, pheasant, rooks, smaller species of
brids and rabbits are all on the menu.
They will use a variety of hunting techniques,
from level pursuit flights, to ringing up flights to all out high speed
stoops. She will tend to hunt mornings and evenings and most pursuits
are proceeded by 'still hunting', she will sit at a vantage point waiting
for the right opportunity to come along.
She will always try to bind her quarry in mid
air after the initial strike, quite often the prey is killed on the
first strike. They will not hunt everyday outside of the breeding season
and it is thought that around one in six hunts are successful.
We have long lived in awe of them but have sadly
also been responsible for persecuting them aswell. Fortunately, through
good conservation and protection of nestsites, thay have now reestablished
a healthy breeding population.
The future is looking good for the peregrine
falcon, lets work to keep it that way, they truly are one of the mother
natures greatest creations, so get out there and watch them, and prepare
to be inspired.
