Declining populations of migratory birds are associated with several of these areas. The most serious population declines of passerine birds in North America over the period –, for example, were concentrated in areas of the Adirondack Mountains, the Blue Ridge Mountains, and the Cumberland Plateau that were subject to acid precipitation.
Thiollay’s baseline infor- sive avian atlas projects, resulting in large volumes mation led to his recent startling discovery of recent (Blakers et al.Barrett et al.
