During the winter season, this warbler species takes refuge in my backyard always feeding on bugs and insects. I caught the culprit.
Recently, he started to perch on the nectar feeder used primarily by the Hummingbirds. He suddenly started to suck on the nectar and took possession of the feeder and going further to fight with the hummer. It was funny to watch and the poor hummer perched on a different twig was waiting patiently for his turn to get his ration from the feeder.
