WHITE-TAILED EAGLE
General Information
White-tailed Eagle Haliaeetus albicilla was classified by BirdLife
International (the official Red List Authority for birds for IUCN) as Least Concern
species in 2006 IUCN Red List. It is listed in Appendix I and II of CITES, in
Appendixes I and II of the Convention on Migratory Species (or Bonn Convention),
Appendix II of the Berne Convention on the Conservation of European Wildlife and
Natural Habitats, and Annex I of the EC Birds Directive.
However, in Ukraine, this species is included under category
II in the Red Data Book of Ukraine (1994); therefore information about White-tailed
Eagle is placed on the web-page dedicated to threatened species.
Description. White-tailed eagle has brown body
plumage with a conspicuously pale head and neck and distinctive white tail and
yellow bill and legs. In juvenile birds the tail and bill are darker, with the
tail becoming white with a dark terminal band in sub-adults.
Range & population. White-tailed Eagle has
been downlisted to Least Concern, as a recent reassessment of its European population
suggests that it no longer approaches the thresholds for the IUCN Red List criteria.
Following a large recovery in many European countries during 1970-1990, the species
continued to increase virtually everywhere during 1990-2000, including key populations
in Norway and European Russia (which together hold >55% of the European population).
A few small populations in extreme southeast Europe continued
to decline, but these losses were outweighed by large increases farther north
and west. The European population is now estimated at 5,000-6,600 pairs, encompassing
50-74% of the global population. Although some losses may be taking place in Asian
Russia due to increased logging and oil industry development, these are outweighed
by increases in Europe. Populations in Kazakhstan are also increasing. The species
has its strongholds in Norway and Russia, and important populations in south-west
Greenland (to Denmark), Sweden, Poland and Germany. Smaller numbers breed in Iceland,
United Kingdom, Finland, Estonia, Latvia, Lithuania, Belarus, Austria, Czech Republic,
Slovakia, Slovenia, the former Yugoslav states, Bulgaria, Romania, Hungary, Moldova,
Greece, Turkey, Iran, Armenia, Georgia, Azerbaijan, Ukraine, Kazakhstan, Turkmenistan,
Mongolia, mainland China, and Japan. It formerly bred in Algeria and may still
do so in Iraq.
White-tailed Eagle requires large and open expanses of lake,
coast or river valley, within the boreal, temperate and tundra zones, nearby to
undisturbed cliffs or open stands of large, old-growth trees for nesting. Its
food is vertebrates (fish, mammals and especially birds), from marine, freshwater
and terrestrial environments. It is mainly migratory in the north and east of
its breeding range, but sedentary elsewhere. Threats that affect this species
include loss and degradation of wetlands, human disturbance and persecution, environmental
pollution, collision with wind generators, and indiscriminate use of poisons.
Modern forestry methods reduce the availability of suitable nesting habitat.
White-tailed Eagle in Ukraine
Estimated number of Ukrainian breeding population is 100-120
pairs. As in Europe, White-tailed Eagle considered to be widespread breeding species
in Ukraine in 19th - early 20th centuries. However, population number has dramatically
declined since early 20th century and achieved the lowest figures in 1950-70’s.
Since 1980’s the population has started to increase.
White-tailed Eagle widely distributes within Ukraine. It breeds
in Dnipro river valley, in North-Western Black sea coastal area, as well as in
eastern and western part of Ukraine. The species may occur in all part of the
country during the migration season.
Woodlands and forest ranges near rivers and large lakes are
the main habitats of White-tailed Eagles.
The species is protected within reserves and protected areas.
According to the national legislation, the birds might be used for limited purposes,
including scientific research, breeding, and dispersal; this requires licenses
from the Ministry for Environmental Protection of Ukraine. Birds can be taken
from the wild also based on the licenses. However, poaching is one of major reasons
of population decline.
Wintering White-tailed Eagle is protected in many regions of
Ukraine as its wintering grounds are located within protected areas, including
Danube Biosphere Reserve, Black Sea Biosphere Reserve, Kanivsky, Dniprovo-Orilsky,
and Roztochya Reserves, Shatsky and Azovo-Syvashsky Nature Parks and Kinburnsky
Landscape Park. There were up to 300 individuals recorded in the latter park in
February 2006.
Threats
There are a number of problems associate with conservation of
the wintering population of the White-tailed Eagle in the Ukraine, and the most
urgent issues are the following ones:
- Decreasing in fish stock and the number of waterfowls that are the main food
sources for the wintering White-tailed Eagle in Ukraine;
- Poaching and disturbance of birds remain urgent in Ukraine. For example,
there is a rapid recent growth of poaching in Mykolayiv and Kherson regions where
birds are taken for subsequent stuffing;
- Significant number of eagles winter in areas with High radiation levels and
feed on waters most of which are polluted by pesticides and heavy metals.
- In areas with high density of the wintering population of the White-tailed
Eagle, no special surveys are conducted, and this threatens development of the
effective conservation measures.
- Low awareness amongst Ukrainian public about wintering White-tailed Eagle
and its conservation needs.
Wintering population of White-tailed Eagle in Ukraine
According to preliminary data, 400-500 White-tailed Eagles wintered
in Ukraine in 2005-2006. Their major wintering grounds located mainly in Southern
Ukraine, in Azov-Black seas region and along Dnipro river. Wintering White-tailed
Eagles occur also near rivers and large lakes in eastern, central and northern
regions on Left bank of Ukraine, as well as in western regions.
The spotty distribution of the species within Ukrainian part
of the wintering ground is determined by availability and distribution of feeding
resources. In winter, White-tailed Eagle feeds mainly on waterfowls. That is why
raptors concentrate near water-bodies, where assemblages of waterfowls (ducks,
geese, coots and swans) stay. These usually are ice-free parts of waters (deep
areas of sea bays and large rivers, ponds near hydropower plants, cooling water
ponds, water-treatment plants, etc.). Their winter diet also includes fish; therefore
White-tailed Eagles concentrate at sites where fishing recourses are available.
Illegal hunting on White-tailed Eagle is the main threat at wintering
grounds in Ukraine. During 1973-2001, there were 20 officially registered cases
of the species persecution in Ukraine. Illegal hunting was registered in Crimea,
Kherson, Poltava and other wintering regions.
In order to protect Ukrainian wintering population of the White-tailed
Eagle, Ukrainian Society for the Protection of Birds started to implement a project
“Conserving Wintering Sites of White-tailed Eagle in Ukraine”.
