Where Have all the Songbirds Gone?
|
Songbirds fly thousands of miles to return to the northern hemisphere every spring, just as regularly as the sun comes up every morning. Or, that’s how it’s supposed to be. But the numbers of migratory birds reaching the north from their winter grounds in the south have plummeted in recent years. One British study found numbers of migratory birds down by 20 percent in just four years, according to the Telegraph newspaper. A five-year study just concluded in Vermont found 17 new species since the last time an atlas was taken, in the 1970s, but other species have dwindled or disappeared altogether, according to the Burlington Free Press.
