In Greece the Golden Eagle was widespread during the 19th century and the first half of this century over the entire mainland and on many islands both in the Aegean and the Ionian sea. According to the literature Greece harbours two subspecies: Aquila chrysaetos chrysaetos in the continental areas and Aquila chrysaetos homeyeri in Crete (Cramp and Simmons 1989).

FOOD HABITS : The golden eagle feeds primarily on mammals.  It feeds mainly on lagomorphs and small rodents, but also on marmots (Marmota spp.),prairie dogs (Cynomys spp.), ground squirrels (Spermophilus spp.), weasels (Mustela spp.), woodrats (Neotoma spp.), skunks, mice, and rarely, large mammals.  The golden eagle also eats grouse, pheasants(Phasianus spp.), owls, hawks, rock dove (Columba livia), magpies (Pica

spp.), and other birds as well as rattlesnakes, frogs, carrion, and occasionally, fish.

Carpa aegagrus

The wild goat (Capra aegagrus) is a widespread species  of  goat  with a distribution ranging from Europe and Asia Mnor to Central Asia and Midlle East.It has been listed as vulnerable on the IUCN Red List since 1996. It is considered the ancestor of the domestic goat.

Lepus europaeus
The European hare (Lepus europaeus), also known as the brown hare, is a species of hare native to Europe and parts of Asia. It is among the largest hare species and is adapted to temperate, open country. Hares are herbivorous and feed mainly on grasses and herbs, supplementing these with twigs, buds, bark and field crops, particularly in winter. Their natural predators include large birds of prey, canids and felids. They rely on high-speed endurance running to escape predation, having long, powerful limbs and large nostrils.

Generally nocturnal and shy in nature, hares change their behaviour in the spring, when they can be seen in broad daylight chasing one another around in fields. During this spring frenzy, they sometimes strike one another with their paws ("boxing"). This is usually not competition between males, but a female hitting a male, either to show she is not yet ready to mate or as a test of his determination. The female nests in a depression on the surface of the ground rather than in a burrow, and the young are active as soon as they are born. Litters may consist of three or four young and a female can bear three litters a year, with hares living for up to twelve years. The breeding season lasts from January to August.

The European hare is listed as being of least concern by the International Union for Conservation of Nature because it has a wide range and is moderately abundant. However, populations have been declining in mainland Europe since the 1960s, at least partly due to changes in farming practices
