The yellow-rumped warbler is the "myrtle" warbler, found in the boreal forests of the eastern United States and Canada and in the mountainous west. Every autumn, they gather together and migrate to the south. I photographed this warbler during the colorful fall season. Usually at this time of year, all the warblers have completed their migration. A flock of warblers arrived late in Toronto due to warm temperature. Birds hide and hunt insects on beautiful red leaves of EOL − Rhus typhina.
