Focusing on families and their shared traits makes bird identification easier than ever. This guide takes readers beyond merely identifying birds to understanding them. Many birders can tell the difference between a White-eyed and Bell's Vireo but cannot begin to describe a vireo and what distinguishes members of this family from warblers or flycatchers. The "species by species" approach makes it difficult to appreciate birds for what they are: members of well-organized groupings united by common traits. Putting the focus on families, and their shared characteristics, makes bird identification easier and more meaningful. More than 150 color photos illustrate the 81 bird families of the United States and Canada.

S2We determined population trends and habitat occurrences for bird species in 14 national forests located in the Southern Region from 1992-2004. We estimated population trends for 144 species within: 14 national forests, 10 physiographic areas, and in the Southern Region as a whole. Habitat occurrences were estimated for 114 species based on 13 forest types and four successional stages. We discussed results for 48 species of management concern along with information compiled on conservation status and the U.S. Geological Surveys (USGS) Breeding Bird Survey population trend estimates. There was evidence that populations increased for 42 species and decreased for 38 species on national forests in the Southern Region as a whole. Trends for many species varied widely across physiographic areas and national forests. Most species were found across a variety of habitats, though associations with particular forest types and structural conditions were often apparent. S3.
