Lanner Falcon (Falco biarmicus)

Lanner Falcon (Falco biarmicus)


The Lanner Falcon is a large falcon that is mostly an African species, which also occurs in small numbers in the Middle East, the Arabian Peninsula, south-eastern Europe and Italy.
In Europe, the species is found in Italy, Croatia, Montenegro, Bosnia and Herzegovina, Serbia, Macedonia, Albania, Greece and Bulgaria (although only in low numbers in most countries).
Capable of breeding with two or three years old. Like all other falcons, Lanner Falcons doesn’t  build nests on their own. Breeds mostly on cliffs, but breeding in other bird’s nests on trees or pylons is also known.
First documented presence of the species in Bulgaria was in 2010 in the Kresna Gorge. It seems that the Lanner Falcon could has been present here previously, but it was discovered when the ornithological observations were intensified in the area, after the Griffon Vulture reintroduction has started. Finding the species in this part of Bulgaria is logically as the habitat is suitable. Strangely the species’ areal is described to follow the Bulgarian border line with FYR Macedonia to the west and along Greek border  to the south. It also appears that the Lanner is positively affected by the concentration of ravens (Corvus corax) and prey species around the feeding sites for vultures. The concentrations of ravens around feeding sites let them to build nests not only on rocks, but also on pylons and thus create nesting sites for the Lanner, which should not compete for nest sites with the more abundant Pergerine Falcon.
