This arrival pattern seemed odd and different from arrival patterns of typical migrants in this habitat, such as Dickcissel, Indigo Bunting, Field Sparrow and Orchard Oriole... Read More

During the breeding season, Cerulean Warblers nest in deciduous forests of the eastern United States and Canada. Over about the last twenty years, much research has focused on improving our knowledge of the biology of this species to inform conservation and reverse this decline. Read More
