In Yamal the researchers completed the scientific expedition to the railroad line “Obskaya-Bovanenkovo” for monitoring of population of the Red Book gyrfalcons that make nests on railroad bridge crossings. The birds stopped being afraid of humans, so the scientists were able to install automatic cameras on their nests, as it is informed in the Instagram account of the Arctic Research Station of the Institute of Plant and Animal Ecology, Ural Branch of the Russian Academy of Sciences.
During the expedition 45 bridges were examined. They are located in the northern part of the route. In total six nests of gyrfalcons were found. The researchers mark quite unique adaptive changes in the behavior of some grown-up birds — they are no longer afraid of humans and do not fly away from the nest, when they approach. The automatic cameras were installed on three nests to find out specifics of the nesting biology of the unique gyrfalcon population.
The gyrfalcons have made nests on the bridges for five years and have stable food base. The gyrfalcon nestlings appeared in their nests earlier than usual this year, because the early spring came to Yamal. The birds do not leave the Arctic for winter, and they start laying eggs in April.
The expedition was organized by the company “Gazpromtrans” with support from the government of Yamal.
The gyrfalcon is the world’s largest species of falcons. It is included in the Red Book of the International Union for Conservation of Nature and in the Red Book of the Russian Federation. This species was included in Red Book of Yamal-Nenets Autonomous Okrug in the first category as being under the threat of extinction. Their nesting site was first registered on the bridge crossings in 2014. Regular expeditions for monitoring of their population on the railroad bridges have been taking place since 2016.
