Confusing Fall Warblers

Confusing Fall Warblers
It’s that time of year again when even the most experienced birder might be puzzled by thecommon_yellowthroat_female_fall fall plumage of warblers.  For new birders, fall warblers can be a real challenge as not only are they much quieter (so it’s often difficult to make the ID with sound), but their molt takes them into more subdued colors. During migration, some birds are still in the process of molting so you can see anything from a near fully (although worn looking) spring look, a patchwork mid-molt pattern or a fully drabbed-out fall/winter pattern.

Fortunately there are free tools to help with these ID’s. One of the best is from Princeton University Press, publishers of Tom Stephenson and Scott Whittle’s “The Warbler Guide”.  Their free downloadable pdf of fall warbler plumage is a handy sheet to take with you birding as a reference to the more tricky plumages you might see.  Pack one in your backpack and may very find your ID confidence and bird count are improved this fall!
