Summary
Aural population surveys of owl species were conducted in the Antonovskoye Forest District of Khingansky Nature Reserve for the first time in 2015. The Ural owl was found to be the most abundant owl species with a breeding density of 5 pairs / 20 km2, followed by Oriental scops owl (4 pairs / 20 km2), Northern boobook (2 pairs / 20 km2), and lastly by Eurasian eagle owl, Long-eared owl, and Short-eared owl (1 pair each / 20 km2).
Northern boobooks appear to be expanding their range and increasing their populations across the entire Amur Province, and owl species that feed on rodents are fluctuating with dependence on that food source.
