В работе использованы материалы, накопленные в Банке данных лаборатории зоологического мониторинга Института систематики и экологии животных СО РАН, собранные в период с 1880 по 2022 г. (с перерывами и в основном с 1960 г.) с 16.05 – 15.07 при учёте птиц на маршрутах протяжённостью около 165 тыс. км. На основе факторной классификации выделены шесть типов населения дроздов, границы которых коррелируют с климатическими и географическими особенностями среды, а также семь подтипов сообществ, границы которых различаются в зависимости от степени облесённости и теплообеспеченности. Установлено, что плотность населения и видовое богатство дроздов увеличиваются в южных и западных регионах, тогда как в полярных пустынях и арктических тундрах дрозды отсутствуют. Методология исследования, включая обработку данных кластерного анализа и введение нулевых видов для учёта экстремальных местообитаний, позволила повысить информативность классификаций. Результаты работы могут быть использованы для природоохранных мероприятий и оценки состояния экосистем. </p></abstract><trans-abstract xml:lang="en"><p>The article presents the results of our research on the population size, distribution, and characteristics of thrushes in Northern Eurasia within the 1990 USSR boundaries. The study utilized data from the Zoological Monitoring Laboratory’s database, collected intermittently between 1880 and 2022 (primarily since 1960) during bird surveys conducted from May 16 to July 15 along routes with a total length of approximately 165,000 km. Based on factor classification, six types of thrush populations were identified, whose boundaries correlate with climatic and geographical environmental features. Additionally, seven subtypes of communities were distinguished, varying in boundaries depending on forest coverage and thermal conditions. It was found that thrush population density and species richness increased in southern and western regions, while thrushes are absent in polar deserts and Arctic tundras. The research methodology, including cluster analysis data processing and the introduction of null species to account for extreme habitats, enhanced the informativeness of the classifications. The study results can be applied in conservation activities and ecosystem health assessments.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дрозды</kwd><kwd>летняя численность</kwd><kwd>многолетняя динамика</kwd><kwd>распространение</kwd><kwd>распределение</kwd><kwd>Северная Евразия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>blackbirds</kwd><kwd>summer abundance</kwd><kwd>long-term dynamics</kwd><kwd>distribution</kwd><kwd>distribution</kwd><kwd>Northern Eurasia</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследования, послужившие основой для написания данной статьи, проведены по программе ФНИ государственных академий на 2021 – 2025 гг.
