Drastic Bird Population Declines Reported in U.S. and Europe

According to new research from the National Audubon Society, populations of some of the most common birds in the United States have declined significantly since the 1960s.  The report shows that twenty different common bird species have fallen by at least half since 1967, including Eastern Meadowlark, Northern Pintail, Northern Bobwhite, Snow Bunting, and Greater Scaup. Habitat loss is considered to be a major factor in the declines.

In a separate study, similar declines have been noted in European farmland birds. Research indicates that between 1980 and 2005, numbers of common farmland birds across Europe dropped by an average of 44%. The declines are thought to be a result of agricultural intensification throughout the European Union.

Recent evidence shows the top four sources of anthropogenic mortality of birds in the U.S. and Canada are from:  cats (2.5 BILLION), building collisions (600 MILLION), auto strikes (200 MILLION), and power lines (50 MILLION). These mortalities can be significantly reduced with known solutions.

Over 300 species of birds breed each year in British Columbia - more than any other province in Canada. Sixty-five species breed nowhere else in Canada and for several other species, British Columbia holds the majority of the world population.

  More than one-third of all North American bird species will be soon at risk of extinction.
The recent study by the State of North America's Birds says that over 430 of 1,154 bird species that live in and migrate among Canada, the United States and Mexico are most at risk of extinction.
