What conservation activities are currently being undertaken to benefit cerulean warblers?
A number of groups and agencies are monitoring cerulean warblers on their properties. Also, the Cornell University Laboratory conducted the Cerulean Warbler Atlas Project to determine the number of breeding pairs and productivity, describe nesting habitat, and identify potential threats to the population and its habitat. In addition to the Atlas Project, mentioned above, several other studies are underway to provide information on the life history of cerulean warblers and their habitat requirements, both in breeding and wintering areas. The Service will continue to emphasize and assign high priority to cerulean warbler research and monitoring efforts aimed at gaining a better understanding of threats to the species. To restore breeding habitat, hardwood trees are being replanted in bottomland areas that had previously been maintained as open fields on National Wildlife Refuges, National Forests, and National Parks throughout the cerulean warbler’s breeding range.
