In late February, biologists returned with sobering news from their annual trip to the bird's wintering grounds in Tierra del Fuego, Chile.An online version of the state's proposal is here, for anyone who wants to read and comment on it. Comments must be received by March 19. It looks like comments have to be submitted by mail even though NJDEP asks for an electronic copy.
