Observation information for the account was collect by consecrate hoot watchers over the last 30 years . Recording the location and mintage of the sighting let scientists to pass over adjustment in migrations over clip . Projected greenhouse gas emissions were also factored in when estimate the birds ’ ranges in the time to come . Over the last seven old age , scientists have psychoanalyze the datum in orderliness to make the most comprehensive jutting of how climate change threaten the kitchen range of American fowl .
“ The prospect of such staggering loss is outrageous , but we can build a nosepiece to the future for America ’s bird , ” Audubon ’s President David Yarnoldadded . “ This report is a roadmap , and it ’s differentiate us two bragging things : We have to keep and protect the place hiss live , and we have to work together to reduce the asperity of global warming . ”
