Falcons
There are about 35 species of falcons found in the world of which
we have several at the centre. They are all closely related and come
a single genus – Falco, which is latin for scimitar shaped;
a shape which can be seen in the classic falcon wing shape. They are
all superbly adapted for flight relying on their speed and agility
to catch their prey. Speed is most dramatically demonstrated during
the stoop where a falcon dives upon its prey from a great height.

Hawks
The true hawks – coming from the genus accipiter, have short
wings and long tails, making them highly manoeuvrable. This agility
makes them well adapted to chasing prey though densely wooded areas.
The female is larger than the male and this allows them to hunt
different prey which increases survival chance for the species.
There are a number of hawk like birds belonging to the buzzard
family of which we have three here at the centre; the Harris Hawk
which is a barabuteo – or buzzard like hawk and the Ferruginous
Hawk and the Red Tailed Hawk which are buteo hawks. Technically
these are classified as buzzards but they are sufficiently hawk
like to be given the common name hawk. |
Buzzards
Buzzards belong to the same family as the hawks and eagles and share
many of the same characteristics although their broad wings are longer
than their hawk counterparts allowing them to seek prey by soaring
seemingly effortlessly on thermals. This makes them much more suited
to hunting over open or sparsely wooded ground and they are in general
less manoeuvrable than the hawks. |

Eagles
Eagles whilst belonging to the same family of birds as the hawks and
buzzards are not themselves all directly related. The true eagles
belong to the genus Aquila which is Latin for Eagles; however, the
term is applied to a large variety of unrelated birds of prey. The
one thing that most eagles have in common irrespective of size is
their strong powerful build, large feet and heavy beak. This helps
ensure that they achieve a kill when catching prey. |
Kites
Kites are exceptional amongst the birds of prey as they have an extremely
light wing loading; this is where the wing area is very large in comparison
to their body weight. This ability enables kites to soar and manoeuvre
without any visible effort. They often even feed on the wing by passing
food from their feet to their mouths. Kites as a group are highly
adaptable and will often be found near human civilisation as they
will scavenge whenever possible. Indeed the Red Kite was once common
in large towns and cities throughout Britain before its widespread
persecution in the 19th Century. |

Vultures
The vultures are roughly divided into New World vultures of which
there are seven species that live in the Americas and Old World
Vultures which are more closely related to eagles and hawks and
are found in Europe, Africa and Asia. The two types whilst sharing
a common evolutionary niche are in fact unrelated; it is thought
that the New World vultures are actually related to storks and herons.
Common features include long broad wings and feeding upon carrion.
Many vultures have bare feet, heads and necks to prevent contamination
from carcasses. At the centre we have two species of New World vultures
which are often found together in the wild. |
Owls
Whilst not related to the daytime or diurnal birds of prey the owls
are a large group of birds which fill their niche at night or during
the twilight hours of dusk and dawn. They are perfectly adapted to
hunting in low light conditions. Their large eyes are set at the front
of their heads giving them the best binocular vision of any birds
and have a larger quantity of ‘rod’ cells than usual to
enhance vision in twilight. The most striking feature of the owls
is their facial disc which makes them appear very human like. The
facial disc however, is a superb adaptation allowing their hearing
to be amplified greatly to the point where many owls are able to hunt
in complete darkness using only their hearing to pinpoint prey. Their
silent flight means that they are then able to pounce in the darkness
without disturbing their meal. |
