In a report from treehugger.com:
The 2011 State of Birds report is out, and this year there is a keen focus on how more attention to the conservation of public lands is the real muscle behind conservation of birds. From airidlands to coastlines, it's public spaces where most species of birds do best, but even here, the majority of species are under threat.
As the report points out, it is more than just conservation of public lands that is necessary to help bird species recover, but so too is conservation efforts on surrounding private lands, and even working internationally with countries to which threatened and endangered bird species migrate.
