We assessed the flocking behavior of birds on St. John and St. Thomas, U.S. Virgin Islands, with systematic surveys along trails in moist forests. Winter residents (species breeding in North America and that winter in the Virgin Islands), all of which were warblers, comprised 91% of the individuals found in 28 flocks but only 49% of solitary individuals. The average flock size was 4.0 individuals of 3.1 species, and did not differ between St. John and St. Thomas even though the average forest tract on St. John (1,000 ha) was much larger than on St. Thomas (62 ha). Northern Parula …
Protecting Forests For Wildlife, Robert A. Askins
Protecting Forests For Wildlife, Robert A. Askins

The subject of managing forests for wildlife is being viewed from a new perspective, a perspective that has developed primarily as a result of studies of forest-interior birds. Forest-interior birds are dependent to a large extent on how forest lands are managed. They are essentially forest specialists and are not normally seen in open areas such as the suburbs, open fields or meadows. In Connecticut and other parts of the northeastern United States, most forest-interior birds are members of one taxonomic group, the wood warblers.
