Summary

Knowledge of the breeding ecology of Endangered Nordmann’s Greenshank Tringa guttifer is necessary to develop a comprehensive species-specific conservation plan. We found nine greenshank nests in Schaste Bay, Russian Far East during the summers of 2019–2021. These are the first nests found in over 40 years and the only discovered to date on mainland Russia. In contrast to previous nest descriptions, we found greenshanks do not exclusively nest in trees, but also place nests on the ground at the base of mature or sapling larches. Our results indicate greenshanks may be larch obligates during the breeding season, and protecting coastal larch forest ecosystems near bogs, meadows, and mudflats throughout the Russian Far East may be critical to the species’ conservation.

Знание экологии размножения охотского улита, находящегося под угрозой исчезновения, необходимо для разработки комплекса мер его охраны. В период полевых исследований 2019-2021 гг. в заливе Счастья на Дальнем Востоке России мы нашли девять гнезд охотского улита; гнезда были обнаружены впервые за более чем 40 лет и впервые на материковой части гнездового ареала вида. Мы выяснили, что охотские улиты гнездятся не только на деревьях, но и устраивают гнезда на земле у стволов, как высоких, так и низких лиственниц. Мы предполагаем, что лиственницы являются необходимым условием для размножения охотских улитов, а защита экосистем прибрежных лиственничных лесов вблизи болот, лугов и илистых отмелей на Дальнем Востоке России может иметь решающее значение для его сохранения.
