White-tailed Eagles on the Isle of
Mull
If at First You Don't
Succeed.......
Strength and Power
Prehistoric people revered
the strength and power of the Sea Eagle, often burying them
alongside human corpses as a sign of the respect that these
magnificent predators held in the local community.
White-tailed Eagles would
have been a familiar sight to people living in towns and
settlements in the Middle Ages, where they performed an essential
role in helping tidy up the local environment by way of their
opportunistic scavenging of a free meal.
For almost 70 years, this
magnificent bird was lost to the coastal habitats it previously
dominated, amid fears that it may never return. Unlike the Osprey,
which has made such a spectacular return to Summer skies in
Britain after becoming extinct under similar circumstances, the
White-tailed Eagle was never likely to have made a similar
comeback.
The White-tailed Eagle is a
rare vagrant to the British Isles from elsewhere in its European
range, thus was never likely to return to these shores of its own
volition. The Osprey, however, pioneered its own re-introduction
in the 1950’s, thanks to Scandinavian breeders that migrate
through Scotland each Spring.
Abortive Re-colonisation
Two
abortive attempts were made to re-introduce White-tailed Eagles
back to Scotland prior to the ultimately successful Nature
Conservancy Council project that released 82 Norwegian chicks on
the island of Rum over a ten-year period between 1975 – 1985; a
second phase of this programme saw a further 59 Norwegian birds
being released in Wester Ross between 1993 – 1998.
An
adult and two juvenile birds, captured in Norway, were released as
the first, small-scale re-introduction attempt at Glen Etive,
Argyll in July 1959. Whereas the two youngsters quickly adapted
to their new surroundings and learned to fend for themselves, the
adult appeared suspiciously tame and was re-captured after
attacking chickens at Appin!
In
1968, the RSPB brought another four Norwegian eaglets for release
on Fair Isle, one of the most isolated islands in the British
Isles (located between the islands of Orkney and Shetland).
Despite initial hope, this small number of birds proved
insufficient to provide the necessary encouragement that a new
chapter in the natural history of the White-tailed Eagle was about
to be written. |
