North America has lost more than 1.5 billion birds over the past 40 years, says the most comprehensive survey of landbird populations in Canada and the U.S. to date, and 86 species are threatened with total extinction—all thanks to human-caused habitat destruction and climate change.

"Among those 86 species, 22 have already lost at least half of their population since 1970 and are projected to lose another 50 percent of their numbers within the next 40 years," reported the Canadian Press. "For at least six species, this 'half-life' window is fewer than 20 years."
"The information on urgency is quite alarming," study co-author Judith Kennedy of Environment Canada said to the Canadian Press. "We're really getting down to the dregs of some of these populations."
"I don't want my grandchild to go out in the forest and not hear the songbirds in the spring and that seems to be where we're headed right now," Andrew Couturier, senior analyst at Bird Studies Canada and a co-author of the report, told the Globe and Mail.
The California condor, Gunnison sage grouse, ivory-billed woodpecker and Bachman's warbler are a few of the more well-known species on Partners in Flight's "Red Watch List," meaning they are the most at risk of extinction.
Those facing the most dramatic population declines are grassland birds, sagebrush and desert scrub species "and forest species dependent on specialized structural features or natural disturbance," the report says.
Indeed, another recent study just confirmed that the habitat of endangered sage grouses in 11 western U.S. states is being torn up because of "rampant" oil, gas and gold mining, precipitating the devastating loss of most of their chicks, the Washington Post reported Thursday.
The Globe and Mail noted:
"Even relatively abundant birds are dwindling in number, the report says. Chimney swifts, field sparrows and short-eared owls are among the common species that have lost more than half of their populations since 1970 and are expected to lose half of their current level in 40 years or less."
"Birds are often a bellwether of broader ecological health," Kennedy said to the Globe and Mail. Kennedy "noted that sickly birds were an early warning sign of the environmental damage caused by the pesticide DDT a generation ago."
"In some ways, the status of these birds could indicate the status of our own health," Kennedy warned.

It is pretty amazing that in this moment when the COVID-19 outbreak has much of the country holed up in their homes binging Netflix, the most watched show in America over the last few weeks has been focused on wildlife trade — which scientists believe is the source of the COVID-19 pandemic. Make no mistake: Tiger King: Murder, Mayhem and Madness is about wildlife trade and other aspects of wildlife exploitation, just as surely as the appearance of Ebola, SARS, MERS, avian flu and probably COVID-19 in humans is a result of wildlife exploitation. As a conservationist, this is one of the things I've been thinking about while watching Tiger King. Here are five more:

With the coronavirus pandemic quickly spreading, U.S. health officials have changed their advice on face masks and now recommend people wear cloth masks in public areas where social distancing can be difficult, such as grocery stores.
But can these masks be effective?

Bayer AG is reneging on negotiated settlements with several U.S. law firms representing thousands of plaintiffs who claim exposure to Monsanto's Roundup herbicides caused them to develop non-Hodgkin lymphoma, sources involved in the litigation said on Friday.
With many schools now closed due to the current COVID-19 outbreak, you may be looking for activities to keep your children active, engaged, and entertained.
Although numerous activities can keep kids busy, cooking is one of the best choices, as it's both fun and educational.
Germany's target for renewable energy sources to deliver 65% of its consumed electricity by 2030 seemed on track Wednesday, with 52% of electricity coming from renewables in 2020's first quarter. Renewable energy advocates, however, warned the trend is imperiled by slowdowns in building new wind and solar plants.
