Results of comparison of an abundance and distribution of Eurasian Oystercatchers in vicinities of village Ivanovka of area Jalutorovsk of the Tyumen region in the summer 1982 and 2011 are submitted. Bird’s censuses are carried out to both years from the middle of May up to the end of August. In both years Eurasian Oystercatchers inhabit, basically, the rivers of Tobol and flood-plain landscapes. The abundance of Eurasian Oystercatchers in both years from second half of May on first half of July decreased, and from second half of July it on a key plot did not meet. On the river Tobol and flood-plain forest-meadow landscape in the summer of 2011 the average abundance of Eurasian Oystercatchers has tripled in comparison with 1982, and on the average on a key plot twice. In 1982 of Eurasian Oystercatchers it is not met in forest- meadow above flood-plain landscapes and village, and it inhabit here in 2011. In village Ivanovka it was fed on the places of the ploughed ground - potato fields.
