There are bird species found here and nowhere else on Earth. Caucasian Snowcock:
As the old Georgian saying goes: "თქვენ იცით, რომ თქვენ არ გადაძვრა მაღალი როცა შურთხი ფრენა ქვეშ თქვენ". Or: "You know you have climbed high when the Snowcock fly beneath you".
This is a more typical view from underneath the bird of the mountain tops:
Some stunning mountain residents, Güldenstädt's Redstart:
Plus a fabulous selection of local residents and migrants on the East Africa-Asian flyway:
Caucasian Water Pipit:
Caucasian Ring Ouzel:
There were also some great raptors. Migrants included many hundreds of Honey Buzzard and Steppe Buzzard; Sparrowhawks, Hobbies, Long-legged Buzzard and one Steppe Eagle. Locals included this incoming Griffin Vulture...
... and Lammergeier:
One of three adult Lammergeiers that circled low over me, as I pretended to be a rock while I photographed Great Rosefinch. These huge vultures have a 2 meter wingspan, the sky literally turned dark, before I fled for my life.
All this, and Wallcreeper too. Highly recommended :-)
