Abstract

In 2015–2019, young bluethroats were caught in order to determine the parameters of their migration stop in the taiga zone in the east of the Russian Plain. A total of 272 birds were analyzed, of which 186 were males and 86 were females. The average duration of the migration stop for young bluethroats was 1.45 days. Transient individuals have fat reserves that allow them to make migratory jumps lasting an average of 4.39 ± 0.20 h. Bluethroats with an average stopping time have a mass deposition rate of 0.04 ± 0.36 g per day and, by the time of departure, are able to make nonstop flights lasting an average of 3.89 ± 0.58 h. Individuals that make the decision to stop lose a little of their fat reserves, reducing their ability to fly nonstop until the next stop. The significance of the river valleys in the east of the Russian Plain for a successful stopover remains an open question, and it has not been fully clarified whether these places have the necessary ecological conditions for the successful stopover of small birds.

在俄罗斯东部平原中泰加地区条件下蓝鸮幼鸟（Luscinia svecica Linnaeus, 1758）秋季迁徙中途停留的参数

摘要 2015-2019年，为了确定蓝喉雏鸟在俄罗斯平原东部泰加地带迁徙停歇地的参数，捕获了蓝喉雏鸟。共分析了272只鸟类，其中186只为雄鸟，86只为雌鸟。幼蓝鸟迁徙停歇的平均时间为 1.45 天。短暂停留个体的脂肪储备使其能够进行平均持续 4.39 ± 0.20 小时的迁徙跳跃。平均停留时间为每天 0.04 ± 0.36 克的蓝胸噪鹛在出发前能够进行平均持续 3.89 ± 0.58 小时的不停歇飞行。俄罗斯平原东部的河谷对成功停歇的重要性仍是一个未决问题，这些地方是否具备小型鸟类成功停歇所需的生态条件也尚未完全明确。

期刊介绍： Contemporary Problems of Ecology is a multidisciplinary periodical that publishes original works on the following subjects: theoretical and methodical issues of ecology, regional aspects of ecology, regional ecological disasters, structure and functioning of ecosystems, anthropogenic transformation of ecosystems. All basic aspects of modern ecology, including the most complicated interactions between living organisms and their environment, are presented. Some of the journal issues are dedicated to global changes in biological diversity at various levels of organization (populations, species, ecosystems) principles and methods of nature conservation.
