Abstract
The materials of year-round bird counts conducted by the authors in Omsk from September 2006 to Au-gust 2009 in nine habitats, as well as on the territory of four municipal districts of the Omsk Province from June 1 to August 10, 2020 have been analyzed. The species richness was studied, the analysis of the species numbers and distribution was carried out, and the abundance of Motacillidae on the territory of the studied administrative districts is indicated. Species sketches are given, in the compilation of which special attention is paid to the nature and duration of stay, as well as the distribution of birds by habitat. It was found that the encountered representatives of this family inhabit all studied biotopes, but some spe-cies are not evenly distributed.

Summary
Район исследования расположен на юге Западно-Сибирской равнины и ограничен административными границами Омской обл. В основу настоящей работы положены материалы количественных учетов птиц, проведенных в г. Омске на постоянных и строго фиксированных маршрутах с 1.09 2006 г. Также были проведены учёты на нестрого фиксированных маршрутах в 21 местообитании, расположенных на территории 4 муниципальных районов Омской обл. Маршрутные учеты проводили без ограничения ширины трансекты, с последующим раздельным пересчетом данных на площадь, по средним групповым дальностям обнаружения интервальным методом [Равкин, 1967; Равкин, Ливанов, 2008]. Омске такие учеты были проведены каждую половину месяца на протяжении трёх лет. Кузякиным [1962] шкалу балльных оценок обилия птиц (число особей/км). Показатели обилия приведены в скобках, как правило, в среднем за указанный период.
