A new report warns that nearly a third of North America’s bird species are
in trouble. And it says habitat loss is to blame. The Great Lakes Radio
Consortium’s Rebecca Williams has more:
National Audubon Society researchers analyzed data on more than 650 bird
species. They found that since 1966, certain bird populations have been
declining in all habitats.
Birds that thrive in grasslands are especially at risk. The study found 70
percent of grassland bird species are declining significantly.
Greg Butcher is the study’s lead author. He says today’s farming practices
have reduced available bird habitat.
“In the 50’s, field sizes were small, there was a lot of variety of crops
being planted, there were a lot of hedgerows and field edges that were good
for bird populations. Most farming is done road to road now. And so, in the
1950’s, agricultural landscapes were very favorable for bird populations,
and today, they’re just not.”
Butcher says creating grass buffers around farm fields can help some
grassland species. But he says other species need larger areas of land to
succeed.
