Eagle Catching Fish
The
White-tailed Eagle (Haliaeetus
albicilla)
is a very large bird of prey in the family Accipitridae which
includes other raptors such as hawks, kites and harriers. It is
sometimes known as the (Grey) Sea Eagle or Erne.
This
is a very large eagle which breeds in northern Europe and Asia.
It has been successfully re-introduced to Scotland.
Birds
in the south of its range are resident, but the most northerly
birds move further south in winter.
The
eagle's diet is varied, including fish, birds, rodents, and
sometimes carrion.
This
is a huge bird with broad "barn door" wings, large head
and thick beak. The adult is mainly brown except for the
distinctive white tail and the yellow bill. In juvenile birds the
tail is darker.
Adult
females have a wingspan of approximately 2.4 meters. Males are
smaller than the females.
White-tailed
Eagles are sexually mature at 4 or 5 years of age. The nest is a
huge edifice of sticks in a tree or coastal cliff. Nests are
reused if undisturbed.
Mated
pairs produce between one or two eggs per year, but it is rare
for both chicks to successfully fledge. Thus, surplus chicks are
sometimes removed from nests to use in reintroduction programs in
areas where the species has died out.
In
such programs, the birds are raised in boxes on platforms in the
tree canopy and fed in such a way that they cannot see the person
supplying their food, until they are old enough to fly and thus
find their own food.
Sea
eagles are more social than many other raptor species: an adult
eagle looking for a nesting site is more likely to select a
location that contains other immature eagles than one with no
eagle population.
This
eagle is believed to be the one in Polish Coat of Arms.
