A proficient scavenger, the Eurasian griffon typically feeds on the soft tissue of medium to large-sized mammal carcasses (3). It has also been known to approach injured or weak sheep and cattle (5). Historically, the Eurasian griffon fed mainly on wild prey such as mountain goats, deer and gazelles; however, these have been largely replaced by domestic species, such as sheep, goats, cows and horses, on which the Eurasian griffon is now often completely dependent (3).
Eurasian griffons co-operate in searching for food by individually circling a particular area, still in sight of their neighbour, until food is found, at which point a large number of birds may swoop down to feed on the carcass. This can lead to impressive threat displays and fights as each individual jostles to maintain its position at the feeding site (2).
The Eurasian griffon breeds colonially. Colonies generally contain 15 to 20 pairs (2), but can comprise up to 150 pairs (3). The bond between each male and female pair is often life-long and beautiful courtship flights can be observed around the nesting cliffs (2). Breeding usually starts early in the year, no later than the end of January (5).
The nest is built on a cliff-face, preferably in a protected ledge or cave (3). A single egg is laid (5), and incubated for 52 days by both the male and female (2). The fledglings and juveniles receive food from their parents for three months (5).
