Springtime colors - Yellow-Rumped Warbler by Georgie Alexon Via Flickr: This photograph of a Yellow-rumped Warbler was taken on a warm sunny spring day in Calgary, Alberta Canada An interesting fact about these birds is that The Yellow-rumped Warbler is the only warbler able to digest the waxes found in bayberries and wax myrtles. Its ability to use these fruits allows it to winter farther north than other warblers, sometimes as far north as Newfoundland.
