Arthur T Knackerbracket has found the following story:

Disappearance of meadows and prairies, expansion of farmlands, use of pesticide blamed for 29 percent drop since 1970.

The number of birds in the United States and Canada has dropped by an astonishing 29 percent, or almost three billion, since 1970, scientists said on Thursday, saying their findings signalled a widespread ecological crisis.

Grassland birds were the most affected, because of the disappearance of meadows and prairies and the extension of farmlands, as well as the growing use of pesticides that kill insects that affects the entire food chain.

"Birds are in crisis," Peter Marra, director of the Georgetown Environment Initiative at Georgetown University and a co-author of the study published in the journal Science, was quoted by Reuters as saying.

Forest birds and species that occur in a wider variety of habitats - known as habitat generalists - are also disappearing.

"We see the same thing happening the world over, the intensification of agriculture and land use changes are placing pressure on these bird populations," Ken Rosenberg, an ornithologist at Cornell University and principal co-author of the paper in Science told AFP news agency.

"Now, we see fields of corn and other crops right up to the horizon, everything is sanitised and mechanised, there's no room left for birds, fauna and nature."

More than 90 percent of the losses are from just 12 species including sparrows, warblers, blackbirds, and finches.

The figures mirror declines seen elsewhere, notably France, where the National Observatory of Biodiversity estimates there was a 30 percent decline in grassland birds between 1989 and 2017.

    Good, good, next you fly into a murderous rage when the bitches don't believe your word that you can't get them pregnant. It's a slippery slope to serial killing all women, but you've taken your first heroic step.
