That's EXACTLY the kind of question this survey is hoping to answer! Here's what the project protocol (http://ebird.org/content/ebird/wp-content/uploads/sites/55/Kirtlands-Warbler-Migration-Blitz-2017-protocol.pdf) says about that question: "Currently, we do not know much about the habitat types used by Kirtland’s Warblers during migration. Our expectation is that they use young, short-stature forests with structure similar to their breeding and wintering habitats. We are focusing our sampling efforts on scrub habitats, secondary-growth forests, and regenerating coniferous forests, but Kirtland’s Warblers could be found in almost any habitat! FLORIDA: After spending the winter in The Bahamas, Kirtland’s Warblers will make their first landfall in Florida. In Florida, we will focus on scrub habitats, and regenerating stands of coniferous forests. Individuals have also been observed along the coast, but we’re hoping to get a better understanding of the inland habitats they use while migrating through Florida."
