No observer familiar with the Red-eyed Vireo or the Wood Thrush on its breeding grounds would expect to find it or other arboreal species among the sand dunes of the Alabama coast but one of the interesting phenomena associated with migration is the occurrence of birds in most unusual habitats. In order to experience this phenomenon, however, the observer will need to visit the coast only when the weather conditions are favorable. The word “favorable” is not used here to imply suitability for picnics, swimming, or most other human activities, but favorable to the grounding of birds which would otherwise pass over the coastal region and continue into more congenial habitat.
