While most warblers migrate to the tropics in the fall, the Yellow-rumped Warbler is able to survive in parts of the United States as far north as Seattle and New England during fall and winter.
The Yellow-rumped Warbler is the only warbler that has the ability to digest waxes found on berry coatings, making them versatile in switching their diets from insects to berries as cold sets in.
Yellow-rumped Warblers are highly recognized by the yellow patches on their sides and rump.
They are nicknamed by some as “Butterbutts”. The next photo shows why!
Always nice to see little flits of yellow patches in the trees!
