“If you were alive in the year 1970, more than one in four birds in the U.S. and Canada has disappeared within your lifetime.

According to research published online in September by the journal Science, wild bird populations in the continental U.S. and Canada have declined by almost 30% since 1970.

‘We were astounded by this net loss across all birds on our continent, the loss of billions of birds,’ said Cornell Lab of Ornithology conservation scientist Ken Rosenberg, who led an international team of scientists from seven institutions in the analysis of population trends for 529 bird species.”
