The Common Yellowthroat and Cape May Warbler can be distinguished by their plumage and habitat preferences. The Common Yellowthroat typically has a more uniform yellow underpart, while the Cape May Warbler features a distinctive yellow breast with black streaks and chestnut ear-patches. Habitat can also be a clue, as the Cape May Warbler is often associated with spruce budworm outbreaks.
