Which habitat feature often concentrates transient White-Eyed Vireos along coastal migration corridors?

Answer

Small patches of dense brush along a river in an otherwise unsuitable landscape.

During migration, even small, seemingly insignificant areas that offer the required dense, shrubby cover can act as vital stopover points for weary travelers. A small, overgrown drainage ditch or a patch of brush along a river, even within a generally poor landscape, becomes a temporary haven because it provides necessary concealment and resources for migrants hugging the coastline.
