Scientists have found that the number of birds in the
United States and Canada has dropped by 3 billion (29 percent) over the past
half-century.
The recent research has given a lot of answers to why
this is happening to avian populations. The research was published in the Journal Science. The results have come as a shock to
everyone.
President of the National
Audubon Society has called the results as “full-blown crisis.”
This new study focused on
more than 500 species of birds to determine what was the cause behind it. Even
the population traditional birds like robins and sparrows is at risk.
As of now the most significant
cause is habitat loss and wider use of pesticides.
