White-tailed Eagle in Jackal Ecological Network

Vanishing Vultures in Indian Peninsula, Jackal with.. relation to look in Europe

First Vulture Restaurant (wildlife observatory) was opened in Romania. In this scene appeared the golden jackal. One can understand, easily, the competition between both scavengers on local level. If we look to larger scale and if we try to see the scarcity of vulture populations, maybe we understand the increasing population trend of other competitors as jackal or feral (stray) dogs.

Munir Virani talks in Nairobi TED Talks on May 2012 (here) about species protection activities and the importance of the vulture's ecology. The Eolian Parks negative impact on bird's population is discussed, too.

After Network 2013, Crispus and Yoluka NGOs Summer Survey in RAMSAR Units SE Romania (see report here), we must include another species into the jackal ecological network, in this case with horizontally relations, the vulture.

Ecology, Threats and Conservation of the White-tailed Eagle Haliaeetus albicilla 

BirdLife International (2013) Species factsheet: Haliaeetus albicilla

The species 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 (Krone and Scharnweber 2003), and indiscriminate use of poisons. Modern forestry methods reduce the availability of suitable nesting habitat. Although some losses may be taking place in Asian Russia owing to increased logging and oil industry development, these are outweighed by increases in Europe.
