Birds are indicator species, acting as acutely sensitive barometers of environmental health, and their mass declines signal that the earth’s biological systems are in trouble, two prominent scientists write
In Opinion John W. Fitzpatrick and Peter P. Marra write, "The loss of nearly 3 billion birds signals a looming crisis that we have the power to stop."
Habitat loss is the main cause of the huge bird declines in North America over the last 50 years. As for climate change, scientists are only now beginning to assess the ravages of warming temperatures on avian populations.
“Birds are indicator species, serving as acutely sensitive barometers of environmental health, and their mass declines signal that the earth’s biological systems are in trouble.”
"Birds are the best-studied group of wildlife; their populations have been carefully monitored over decades by scientists and citizen scientists alike....This study pulls all of that data together, and the results signal an unfolding crisis."

Is this literally "canary in the coal mine" situation for mankind? Three billion (~30%) North American birds have vanished since 1970 "The Crisis for Birds Is a Crisis for Us All" #BringBirdsBack
In other news, aphorists met today to officially change the expression to "the canary out of the coal mine, or really anywhere."
“Birds are indicator species, serving as acutely sensitive barometers of environmental health, and their mass declines signal that the earth’s biological systems are in trouble.”
"While it remains vital to save the most endangered of these #birds, the loss of abundance among our most common species represents a different and frankly more ominous crisis." Co-authors John Fitzpatrick () and on the new study.
