For those who would like birds in their future, the statistics are truly frightening. Neotropical migrants, such as wood thrushes, warblers, catbirds, hawks, wrens, vireos, flycatchers, kingbirds, nightjars, swallows, tanagers, orioles—species that fly thousands of miles to Central or South America to spend the winter—have declined an average of 1 percent per year since 1966 (Sauer, Hines & Fallon 2005). Add up those percentages, and you’re looking at nearly a 50 percent reduction in population sizes for many of our bird species within the space of 50 years.
