Identify warblers in the fall

New generations of warbler species do not develop breeding plumage until the next spring. During the first fall and winter, many first-year and some adults show drab plumages making trouble for identifying them. I provided here paired images with the most similar species to tell them apart.

These images have been drawn by the talented David Sibley.

Some warblers can be similar to other songbirds such creepers and kinglets. Find listed below the most reasonable resemblances among different families.
