“…Of the nine nests we found, seven were located within 40 m of a Cajander larch forest or forest fragment, and two were 150 m from a larch forest but surrounded by sapling larches. Furthermore, all nest sites contained tall (12–15m) larch trees (live or dead), which greenshanks use as perches to watch for potential threats (Pronkevich et al 2022). The arboreal nests found on Sakhalin Island were situated directly underneath broad overhanging larch branches, presumably to provide concealment from avian predators and to shield nests from strong winds and precipitation while allowing birds an unobstructed view of their surroundings (Nechaev 1978).…”

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.
