Исследования проведены в среднетаёжной подзоне в Кеть-Тымском междуречье, которое, как и другие междуречья Томской области, остается плохо исследованным в орнитологическом отношении. Изучено летнее население птиц в четырех лесных и трех болотных местообитаниях. Установлено, что орнитокомплексы долин правобережных притоков р. Кети и сопредельных территорий представлены 131 видом птиц. Плотность их населения и видовое богатство больше в смешанных лесах. Минимальные значения обоих показателей характерны для населения верховых болот. Среди лесных местообитаний суммарное обилие птиц меньше в вырубках по сосновым лесам, а видовое богатство в темнохвойной тайге. Обилие птиц лесов района исследования в 1,3-1,7 раза больше по сравнению с расположенными севернее долинами рек Васюган, Тым и Обь-Иртышским междуречьем, а в верховых болотах обилие птиц в 2-4 раза меньше, чем в аналогичных местообитаниях долин Оби и Иртыша в пределах среднетаёжной подзоны. The aim of our research was to reveal the species composition and the quantity (abundance, number) of birds in the valleys of the Ket' River tributaries in the Ket'-Tym' interfluve within Tomsk Oblast. Our study site was situated in the Ket'-Tym' River interfluve (east of Tomsk oblast, Western Siberia), where sprucecedar-birch and pine forests prevail. We examined the valleys of the Paydugina, the Orlovka and the Lomovataya Rivers. All these rivers are the right tributaries of the Ket' River. The Lomovataya River falls into the Ket in its top part (58°54'N, 87°44'E), the Orlovka River in the middle (58°38'N, 86°04'E), and the Paydugina River in the lower part near the settlement of Narym (58°51'N, 81°48'E). The Lomovataya and the Orlovka Rivers are in Verkhneket district, and the Paydugina River is in Parabel district of Tomsk oblast. For the Paydugina River valleys, we studied summer population of birds during 15 June-10 July 2008, for the Orlovka and the Lomovataya River valleys during 15 June-10 July 2009. Our transects covered 6 types of habitats: mixed forests, pine forests, cuttings down in pine forests, dark-coniferous forests, bogs with tall pines, bogs with stunted pines and open sphagnum high bogs with lakes and stunted pines. At key sites, we recorded all encountered birds determining the distance between them and the record-keeper with a further square recalculation. The species taking the 1-5th places in this population variant were considered leading in the abundance (Ravkin, 1967; Ravkin and Livanov, 2008). Generally, we found 131 bird species from 16 groups in the period of works on the territories under investigation. The population density and species diversity of birds are higher in mixed forests (See Tables). The minimum values of both parameters are typical of the population of high bogs. Among forest habitats, the minimum species diversity is in dark-coniferous forests, among bogs in high bogs with stunted pines and open sphagnum high bogs with lakes and stunted pines. In forest habitats, Parus montanus, Fringilla montifrigilla, Loxia curvirostra, Phylloscopus collybita and Fringilla coelebs dominate, in bogs Anthus trivialis, Emberiza leucocephalos, Emberizapusilla, Anthus hodgsoni and Parus montanus. The population density in forest habitats in the valleys of the Ket' River tributaries is 1, 4 times higher than in the valley of this river. The bird's abundance of forest habitats of the Ket' River tributaries in comparison with the same habitats of the valleys of the Ket', the Vasyugan and the Tym Rivers and the Ob-Irtysh Rivers is also higher. The bird's abundance of high moor bogs in the region of our study site is almost twice less than at the Ob-Irtysh River interfluve and 2-4 times less in comparison with the same habitats of the Ob and the Irtysh River valleys.
