Yellow-rumped Warbler, like most warblers, is primarily insectivorous and loves butterflies, caterpillars and flies. It's the only warbler able to digest the waxes found in bayberries and wax myrtles. It is often seen fluttering to catch insects in flight or resting on leaves. It is one of the first warblers that we see in the spring, at the end of April it is back in Quebec, thanks to it's ability to digest berry waxes.
It's not the only warbler with a yellow rump, but it's the brightest and most showy! It is also the most common here!
The Yellow-rumped Warbler can sometimes be seen in winter, thanks to its ability to eat berries!
This warbler can drink tree sap!
