Effect of age at release on the post-release survival of head-started Spoon-billed Sandpipers ...
Headstarting, in which eggs are taken from the nests of wild birds, incubated artificially and the chicks reared in captivity before release to the wild, has been conducted since 2012 on the subarctic breeding grounds of the Critically-Endangered Spoon-billed Sandpiper Calidris pygmaea in an attempt...

Headstarting, in which eggs are taken from the nests of wild birds, incubated artificially and the chicks reared in captivity before release to the wild, has been conducted since 2012 on the subarctic breeding grounds of the Critically-Endangered Spoon-billed Sandpiper Calidris pygmaea in an attempt to increase the production of fledged juveniles.
