- Prothonotary warblers are the only species within the genus – Protonotaria.
- Males build multiple unfinished nests, and females construct real nests.
- The beautiful bird is most often seen in the Cumberland River Basin from April to September in swamps and floodedplains with species of willow, ash, maple, and cypress.
- Loss of habitat threatens this species. Preservation of hardwood swamps and floodplains and allowing for dead trees in these spaces (where the birds nests) can help the bird.
