Songbirds are rapidly changing their tune, figuratively speaking, to cope with deforestation and regrowth.
"Eastern North American songbirds are a pretty adaptable bunch, says a scientist who discovered some remarkable changes in their wings over the last 100 years. A close look at museum collections of 851 songbird specimens belonging to 21 species shows that most of the birds evolved pointier wings after their forests were fragmented by clear-cutting. Others in re-foresting areas evolved less-pointy wings. The reason for the wing changes: nothing less than the drive to procreate."
