First video of rare Nordmann's Greenshank in nest in Russia





This summer in the Russian Far East, an international team of biologists found a nest of a rare, tree-nesting shorebird — the first nest of the species seen in more than 40 years. They took video of the nest — the first ever.

Nordmann’s Greenshank (Tringa guttifer), also known as Spotted Greenshank, has an estimated population of 600-1300 and is listed as globally endangered. It breeds along the southwestern and northern coasts of the Sea of Okhotsk and on Sakhalin Island. It migrates through Japan, Korea, eastern China, Hong Kong, and Vietnam and winters in Southeast Asia. A steep population decline has occurred in recent decades, linked largely to habitat destruction and illegal hunting in Southeast Asia.

“Almost nothing is known about their breeding ecology, which makes this new discovery so important,” said Dr. Vladimir Pronkevich of the Institute of Aquatic and Ecological Problems (Russian Academy of Sciences), the leader of the expedition.

Pronkevich and his colleagues spent more than two months at the Bay of Sсhastye (“Happiness”), in the remote southwestern corner of the Sea of Okhotsk, conducting a pilot study about the bird’s breeding and migration ecology.

The group found the nest on June 17. Unlike most shorebird species, Nordmann’s Greenshanks place their nests in trees. This one, situated on a branch nearly four meters (13 feet) up a larch tree, was constructed of twigs and lined with lichens that helped camouflage the eggs.
