Sea Duck Joint Venture Strategic Communications Plan 2015-2019

The mission of the Sea Duck Joint Venture(SDJV)is to promote the conservation of North American sea ducks through partnerships by providing greater knowledge
and understanding for effective management. SDJV focuses on the 15 species of North American sea ducks on their coastal water habitat for migration and wintering as well as boreal forest and tundra habitat for nesting. Since the JV’s founding in 1998, the four pillars of its work have included science, communications, funding, and conservation.

Holocene underkill, Pleistocene Overkill, Chendytes lawi

PNAS March 18, 2008 vol. 105 no. 11 4077-4078
For many years, it was widely assumed that Chendytes had been lost toward the end of the Pleistocene, even though there were early reports of material from archaeological contexts. Survival well into the Holocene became clear in 1976, when G. V. Morejohn (11) reported C. lawi bones in an archaeological site north of Santa Cruz, California dated to between 5,400 and 3,800 14C years ago. He estimated that the extinction of this bird had occurred between 2,500 and 3,000 years ago.
