How animal waste is helping turn China's lakes green

The Guardian
 
                                 Lest we North Americans feel smug, this image shows                                                           one of countless "eutrophied" sloughs in Manitoba,                                                                                              on the Canadian prairies.                                                                                                                           A PinP photo.

Aerial insectivores--birds that hunt for insect prey on the wing--are declining across North America as agricultural intensification leads to diminishing insect abundance and diversity in many areas. A new study from The Condor: Ornithological Applications looks at how Tree Swallows' diets are affected by agriculture and finds that while birds living in cropland can still find their preferred prey, they may be working harder to get it. More here.
