Ducks were once a conservation bright spot. Now they’re declining in the US, new report shows

A new report says at least 112 North American bird species have lost more than half their populations in the past 50 years. Among the birds showing the steepest declines are Allen’s hummingbirds, Florida scrub jays, golden-cheeked warblers, tricolored blackbirds and yellow-billed magpies. Ducks were once a conservation bright spot, but that trend has reversed, with declines in recent years. The report published Thursday is a collaboration between several conservation and research groups. A third of the species examined are rated as high or moderate concern for conservation due to declining numbers, habitat loss or other threats. A new report says at least 112 North American bird species have lost more than half their populations in the past 50 years.
