Abstract

In recent years, the number of observing the osprey (Pandion haliaetus (Linnaeus, 1758)) in the Altai Krai (Siberia, Russian Federation) has increased slightly. We suppose this fact is due not to an increase in the number of these rare birds in the region, but to an increase in the number of interested observers and amateur photographers. The appearance of such Internet resources as the Web GIS “Red Book of Altai Krai”, the Web GIS “Feathered Predators of the World”, “Siberian Birdwatching Community” and others makes it easy to publish the results of their observations, confirmed by photos, on the Internet, which makes them accessible to a wide audience. Most of the ospreys observed in the region are most likely migratory, stray, or flying single birds. However, regular recording of ospreys during the breeding time on a pond along the river Setovochka between the mountains of Babyrgan and Gladkaya on the border of the Soviet and Altai areas in 1980-2000 allows a high degree of probability to suggest nesting of this bird here.

Highlights

The distribution area of the osprey Pandion haliaetus (Linnaeus, 1758) covers almost the entire territory of Russia except for the tundra and part of the forest-tundra (Kuchin, 2004)
In order to get an idea of the distribution of osprey in Altai Krai, an analysis of available sources, including materials from the Red Book of Altai Krai (2016), data from the Web-GIS “Red Book of Altai Krai”, Web-GIS "Feathered Predators of the World", and the Birds of Siberia site
At the beginning of the last century, the osprey was observed near Biysk, in the upper reaches of the Aley, and in the forests near the river Ob territory at breeding time (Fig.2 for details)

Summary

Introduction

The distribution area of the osprey Pandion haliaetus (Linnaeus, 1758) covers almost the entire territory of Russia except for the tundra and part of the forest-tundra (Kuchin, 2004). In the Altai Krai, the osprey is characterized as a threatened species, and there is currently no reliable information on its nesting in this region (Plotnikov, 2016). The birds stopped nesting in most of the intensively developed territories of Russia (Kassal, 2019). It is listed in the Red Books of the Russian Federation (2001), Altai Krai (2016), and Altai Republic (2017), Kemerovo (2012), and Novosibirsk (2018) regions, and other regions within its habitat. Information about observing osprey in the Altai Krai is extremely scarce (Plotnikov, 2016).
