Barring of northern winds by eastern ridges of the Polar Urals makes weather conditions in the Schutchya River catchment relatively good in a long-term norm. In spite of extremely unfavourable weather conditions in this late, cold, windy and rainy season birds nested in usual dates for the area on watersheds and gentle upper slopes. In floodplain and depressions of large lakes bird numbers were low because of the late ice-melt, but networks of ponds and small lakes, including those in former quarries, were quite densely populated.
Lemmings were rare, but high numbers of voles allowed breeding of Rough-legged Buzzards and Short-eared Owls. Willow Grouse was practically absent.
In early August floodplain of the lower Ob' River was still under water, and few birds, even gulls and ducks, used it. However, wader concentrations were recorded in that time on marshes along the railway under construction and on networks of lakes near Laborovaya settlement. Rough-legged Buzzards could be seen every 5-6 km along the railway Obskaya-Bovanenkovo, where also Short-eared Owls were not uncommon, Snowy Owls and Arctic Foxes were recorded sometimes. Local people reported nesting of a Snowy Owl pair in the area.
