Create a new species, then endanger it

Skiing at New Hampshire's Cannon mountain is being held up because of endangered species Bicknell's thrush. This bird is alleged to nest in wooded areas above 2500 feet.
Bicknell's thrush only became a species in 1995. Prior to 1995 it was called the Grey Cheeked Thrush. Audubon's website reports "Bicknell's thrush is not safely distinguished in the field". In other words Bicknell's thrush looks so much like a gray cheeked thrush that no one can tell them apart.
Cannon has been a top ski area since the 1930's, so it's older than Bicknell's thrush. In short, the skiers came first. Bicknell's thrush was only invented 11 years ago, the skiers have been on the trails for 70 years.
Recipe for driving people off federal lands. Invent a new species. Then declare it endangered.
