The real loser in the eastern forests has been the songbird. One of the most striking losses was the Carolina parakeet, a lovely, innocuous bird whose numbers in the wild were possibly exceeded only by the unbelievably numerous passenger pigeon. (When the first pilgrims came to America there were an estimated nine billion passenger pigeons—more than twice the number of all birds found in America today.) Both were hunted out of existence—the passenger pigeon for pig feed and the simple joy of blasting volumes of birds from the sky with blind ease, the Carolina parakeet because it ate farmers’ fruit and had a striking plumage that made a lovely ladies’ hat. In 1914, the last surviving members of each species died within weeks of each other in captivity. A similar unhappy fate awaited the delightful Bachman’s warbler. Always rare, it was said to have one of the loveliest songs of all birds. For years it escaped detection, but in 1939, two birders, operating independently in different places, coincidentally saw a Bachman’s warbler within two days of each other. Both shot the birds (nice work, boys!), and that, it appears, was that for the Bachman’s warbler. But there are almost certainly others that disappeared before anyone much noticed. John James Audubon painted three species of bird—the small-headed flycatcher, the carbonated warbler, and the Blue Mountain warbler—that have not been seen by anyone since. The same is true of Townsend’s bunting, of which there is one stuffed specimen in the Smithsonian Institution in Washington. Between the 1940s and 1980s, the populations of migratory songbirds fell by 50 percent in the eastern United States (in large part because of loss of breeding sites and other vital wintering habitats in Latin America) and by some estimates are continuing to fall by 3 percent or so a year. Seventy percent of all eastern bird species have seen population declines since the 1960s. These days, the woods are a pretty quiet place.
