Researching the endangered Eastern Imperial Eagle
A joint effort of NABU and the Russian Bird Conservation Union (RBCU)

Not far to the Volga River and over 700 kilometers east of Moscow these two areas are located: Sengileevsky Mountains Reserve and – around 150 kilometres south of the mountains – National Park Tschawasch Warmane. These two areas belong to the main breeding grounds for the rare Eastern Imperial Eagle (aquila heliaca).
Since 2010, we have been committed to the protection of these majestic birds together with our partners, NABU-Kavkaz (the Caucasian sister organisation of NABU Germany) and the Russian Bird Conservation Union (RBCU). In order to plan effective conservation measures, we are researching the eagles' migration routes and breeding behaviour.
What happens to NABU projects in Ukraine and Russia?
Ever since its foundation NABU has been an international organisation. As such, we are experienced with crises. We will try to maintain our nature conservation projects in Ukraine and Russia, which include the Imperial Eagle webcam, for as long as possible. We are convinced that this war, too, can only be permanently resolved through exchange and dialogue. The war in Ukraine must end immediately – for people and nature!

On a global scale, the Eastern Imperial Eagle is an endangered species. With the clearing of pine forests, imperial eagles have lost nesting opportunities. Due to new methods of agriculture the number of prey animals has decreased. Both these factors have contributed to a significant decline of Imperial Eagle populations over the past 30 years. Today, their total European population is estimated at 1,100 to 1,600 breeding pairs. The Volga region is home to approximately 450 of these birds, making it one of the largest populations of Imperial Eagles in Europe and a reproduction hub for the species in Russia.
Efforts to research the Eastern Imperial Eagle
NABU-Kavkaz is researching the Eastern Imperial Eagle to apply the most effective means for its protection. For this purpose, our fellow colleagues have equipped ten imperial eagles with small backpack transmitters in 2018 in order to be able to precisely track their different migration routes. Amongst the ten research specimen were nine fledglings and one mature animal.
In a groundbreaking effort, our team was able to install webcams in two of the about 130 imperial eagle's nests on record in the Volga region. This enables us to monitor the birds' arrival as well as breeding and rearing of the fledglings up close and in real-time. Tune into the livestreams below and witness the beauty of this magnificent endangered animal!

Background information on our Eastern Imperial Eagle projects
For many years, NABU has been involved in species protection in the central Volga region. Since 2010, NABU has been funding the program for "Protection of the Volga population of the Eastern Imperial Eagle in the Volga region" initiated by the local Ministry for Nature Conservation. Led by Dr. Mikhail Korepov, this project is being implemented by NABU-Kavkaz with support from the Ulyanovsk district administration. The expansion of protected areas is at the heart of the collaboration with the local government and partner NGOs. They aim at preserving the steppes and forests that are so typical for the habitat. In this open vegetation, the Imperial Eagle still can find prey and suitable breeding spaces.
Over the course of the past seven years, as many as 70 areas have been converted into protected areas with almost all overground power lines converted for bird safety — a success we are most proud of.
From 2021 on, NABU International Foundation and VGP Foundation support NABU's efforts for the conservation of the species. The project "New Networks for the Eastern Imperial Eagle" is focused on transferring knowledge between existing conservation projects in Russia and Eastern Europe with the aim to improve the conditions for these iconic birds throughout their range. In the scope of the project the Imperial Eagle's wintering areas on the Arabian Peninsula and in Northern Africa will be investigated in order to identify threat factors and improve conservation measures.
More species in need of protection
Snow leopards are among the most endangered big cats on earth. Only 4,000 to 6,400 animals now live in the wild. NABU has been committed to the survival of snow leopards in Kyrgyzstan since 1999 and has extended its commitment to Tajikistan, Pakistan and Nepal. more →
Since survival of large carnivore species is strongly pending on public acceptance, NABU launched a project to create education and information material on wolves. more →
The European pond turtle is among the most endangered animal species in Germany and considered extinct in most of the federal states. The aim of the presented project therefore is to reintroduce the extirpated European pond turtle to Lower Saxony. more →
