Golden
Eagle
Scotland is home to
the highest concentration of these majestic birds anywhere in
Europe, with the majority of these being found in the north and
west.
They are large birds, with a wingspan in excess of 2 metres, and
can often be seen soaring over the remote islands that we encompass
in our boat trips.
They feed largely on carrion, but will also take small mammals and
birds such as grouse. Each pair has a large territory than can be as
much as 18,000 acres.

White-tailed
Sea Eagle
An adult sea eagle can reach a wingspan of
2.4 metres, making them slightly larger than golden eagles. They
tend to soar on flat wings, as opposed to the golden eagle which
generally hold the wings slightly bent upwards in a 'V' shape.
The Sea eagle was hunted to extinction in
Britain, with the last breeding pair being shot on the Isle of Skye
in 1916.
There have been a number of attempts to
re-introduce these birds, but only the most recent program has
proved successful. Since 1976 juvenile birds have been brought in
from Norway and released at secret locations off the West Coast of
Scotland. The first successful wild breeding was achieved in 1985,
and today there are approaching 40 pairs of these giant birds
breeding along the West Coast of Scotland. Indeed, experts are
predicting that in the near future nesting Sea Eagles will be seen
on the Argyll mainland.
It is believed that suitable habitat and food
supplies exist in other parts of Britain, but recolonisation of
England is more likely from their German stronghold, as the bird is
perceived as a threat to domestic livestock, and persecution of
raptors is still a problem in large parts of Britain.
The bird's feeding habits are referred to as
'specialised generalist', as its diet is very varied, from fish to
small mammals, and in some cases sheep, however one particular pair
will specialise in one type of prey. Indeed, experts were surprised
to find deep-water fish remains in one particular nest. The species
of fish was not normally accessible to surface feeding eagles. It
was only after careful observation that it was found that the pair
in question had become expert at robbing otters of their catch!

Buzzard
This bird of hill country and wooded farmland
is a familiar sight in Argyll, and will often be seen gliding in a
hot air thermal or perched on a post at the side of the road..
They are often confused with eagles, but to
the trained eye there are some distinct differences. Not least of
this is their size - they are just over half the size of a Golden
Eagle.
Gamekeepers and rabbits have had a huge
impact on buzzard numbers over the years. Gamekeepers have always
targeted the bird with poisoned bait, although this has declined
from its peak of 100 years ago. Despite this, more buzzards still
die in this fashion than any other raptor.
It is not all bad news for the buzzard
however. Rabbit numbers, decimated by myxomatosis in the early
1950's, have seen a significant increase over recent years. As
rabbits form a large part of the diet of buzzards, they have
prospered as a result and their range is once again expanding.

Peregrine
Falcon
No other bird rivals the peregrine for speed and agility. It feeds
on medium sized birds, such as pigeons, crows, grouse and seabirds,
which it catches in spectacular dives at speeds of between 100 and
200 MPH!
They are birds of mountains, moorlands and sea cliffs, and as you
would expect the inaccessible rocky cliffs of our West Coast islands
make an ideal place for nest sites. The nest itself is usually on a
ledge or crevice, and often is just a bare scrape in the dirt.
Sometimes an old raven's nest will be used. The three to four eggs
are camouflaged to help conceal them, but this has not prevented
nest robberies by eggs collectors being a problem. This, coupled
with a build up of pesticides in the food chain during the 1960's,
and illegal poisoning and shooting by game keepers has had a serious
impact on peregrine numbers throughout the last hundred years.
Today the birds receive full legal protection, and numbers have
largely recovered, so there is every chance we may glimpse the
compact shape of this powerful hunter soaring over the sea cliffs in
the Firth of Lorne.

Osprey
The osprey is a summer visitor to Britain,
spending its winter months in West Africa. They became extinct in
Britain at the end of the 19th Century, largely because of egg
collecting and trophy hunting.
In 1955 a pair returned to breed at Loch Garten near Aviemore, and
so the long road to becoming re-established was begun. The RSPB gave
the birds round-the-clock surveillance of the nest site, and other
known sites were kept a closely guarded secret for many years. An
observation hide was built at Loch Garten to enable members of the
public to view these rare birds. This had a two-fold benefit. It
provided people with easy access to see the birds, without causing
undue disturbance at the nest whilst the birds were raising their
young, and it also helped to educate people on the bird's beauty and
showed their value to the tourist trade in the local area. Indeed
well in excess of one million people have viewed the birds at the
Loch Garten hide, and in the meantime the bird has re-colonised
Scotland and indeed the bird has successfully bred in parts of
England recently.
There are birds nesting in Argyll, and they are sometimes seen
locally. We would not normally expect to see them during our boat
trips, as the islands do not provide suitable habitat, and they tend
to fish on inland lochs rather than over the sea, but we can never
rule out the chance of seeing one over the mainland or in passage
overhead. |
